Preschool Education, Australia methodology

In 2021, the New South Wales Department of Education (NSW DoE) submission to the NECECC consisted of data from two data collections:

• 'Government School Census'
• 'Early Childhood Education (ECE) Annual Preschool Census'

In the 2021 NECECC representative fortnight, large parts of NSW were in lock down due to Coronavirus (COVID-19). Services responded to the lock down in a variety of ways, including scenarios where the service was: closed for part or all of the representative fortnight, provided remote learning, had a minority of children on premises and/or continued normal operations.

Due to this unique situation, and as agreed in consultation with the Australian Bureau of Statistics, the NSW DoE has requested the suppression of a number of variables. Suppressed data are described in the Deviation from the NECECC Standards table.

The organisation responsible for the Government School Census was NSW DoE. Data were collected under the Children (Education and Care Services) National Law (NSW) and the Education and Care Services National Regulations.

The data collected by NSW DoE enabled reporting across the NSW government schools sector for a variety of reporting requirements, as well as to measure progress against Australian Government preschool education targets and reforms.

Scope: The scope of the preschool component of the Government School Census included all children enrolled in a preschool program or Early Intervention class at a government school in NSW. Children are eligible to enrol at a government preschool if they turn 4 on or before 31 July of that year. Priority is given to children from disadvantaged backgrounds who are unable to access other children's services, Aboriginal and Torres Strait Islander children and children from families who experience financial hardship. While the majority of children are aged 4 or 5, if there is spare capacity, places may be offered to 3 year olds.

Children enrolled in an Early Intervention class at a NSW government school have been included in the Government School Census since 2012. Early intervention classes provide preschool education in a preschool setting for children with a disability.

Coverage: The 2021 Government School Census included all government schools in NSW.

Data collection methods: The 2021 Government Schools Census collected data using a unit record level (URL) data collection methodology for children and service providers.

The Government School Census is an annual collection and in 2021 was undertaken on 6 August, with a two-week reference period of 2 August to 13 August. Fortnightly data were converted to a one-week average to enable valid and reliable national comparisons.

The NSW DoE compiled, processed and validated the data before submitting it to the ABS in November 2021.

All NSW DoE government school-based preschools were required to participate in the Government School Census by completing an online census form. There were three sections to the preschool component of the Government School Census:

• general preschool data (e.g. number of children enrolled, number of Aboriginal and Torres Strait Islander children)
• class or group data (overall session details for service and individual enrolment and attendance by child, along with daily fees paid, date of birth, sex, Aboriginal and Torres Strait Islander status, language background other than English, refugee status, disability status, health care card status and suburb)
• teacher data (e.g. qualifications and length of employment)

Indigenous students are identified at enrolment through the enrolment form. In 2015 the Indigenous status question on the form was changed to match the standard national question, with users required to select one of four answers corresponding to the first 4 values of the ECEC NMDS item Person-Indigenous status. The corresponding Indigenous status question on the Enrolment Registration Number (ERN) system matched the standard national question.

Schools were required to answer the question by selecting a single value from an on-screen drop down list. The values available for selection comprised the first 4 values of the ECEC NMDS as well as a supplementary value Unknown/Not Provided to accommodate instances where the parent or carer did not provide this information on the enrolment form. Several records for school-based preschools did not distinguish between Aboriginal children and Torres Strait Islander children. Records for these children were coded as Aboriginal and/or Torres Strait Islander origin not further defined.

During the collection period, NSW DoE extracted children's details from the ERN system. Preschool teachers checked enrolment data, allocated children to class groups and entered enrolment details for any children missing from the ERN. Teachers also entered additional information, such as Health Care Card status, fees paid and attendance, and then electronically submitted the census to the secure DoE Collection portal.

NSW DoE ensured that all preschools submitted compulsory data. Preschools were notified about the data collection through the regular reminder emails and online notices. Detailed instructions on collecting and entering the data using the secure NSW DoE Collections portal were available to preschools at all times during the survey period. The online census contained a number of validation rules to prevent inconsistencies and omissions. During the data collection period, preschool support workers could phone NSW DoE to clarify counting rules and data collection procedures. In addition, data anomaly reports were generated identifying problems such as incorrect age, low attendance or duplicate children. All anomalies were checked and data corrected if required. Signoff was required from all Principals whose school provided a preschool program.

Data collected through the 2021 Government School Census and submitted to the NECECC were broadly comparable with data collected in 2018, 2019 and 2020 as these collections were undertaken using a URL data collection methodology. An analysis of the coherence with other jurisdictional collections should be undertaken on an individual basis, taking into account any data elements that are not consistent with the NECECC standards.

Deviations between the NECECC standards and data collected from the Government Schools Census are outlined in the table below. In 2021, the impact of COVID-19 on service delivery resulted in several additional deviations.

NSW DoE preschools were notified about the Government Schools Census through the regular reminder emails and online notices. Detailed instructions on collecting and entering data using the secure NSW DoE Collections portal were available to preschools at all times during the collection period.

Data sourced from the Government School Census are published as part of Preschool Education, Australia and Microdata: Preschool Education, Australia on the ABS website.

High level aggregate data is also available on the NSW Education Data Hub and Schools: In-Brief and Schools and students - Statistical Bulletin publications.

In January 2017, the NSW Government introduced Start Strong, a new community preschool funding model.  Start Strong is a needs-based funding investment aimed at making 600 hours of preschool participation more affordable. Start Strong targets funding to children enrolled in community preschools who are aged 3 years or over, with additional equity funding directed to children who are Aboriginal and/or Torres Strait Islander or from low-income families as well as children with disabilities and/or additional needs. Additional loadings are also provided to children in outer regional, remote and very remote locations as well as children with additional language needs.

The organisation responsible for the 2021 Early Childhood Education (ECE) Annual Preschool Census is NSW DoE. Data for the ECE Annual Preschool Census was collected under Funding Specifications, which are contracts with each service provider outlining the terms of renewable funding under the Early Childhood Education Grants Program. These preschools and mobile preschools are regulated under the Children (Education and Care Services) National Law (NSW) and the Education and Care Services National Regulations. 

The data collected by NSW DoE was used for state government reporting commitments and to assist with the evaluation and planning of service provision. For preschools, the information obtained was used to determine funding for the following year. The data were also used for a variety of State and Commonwealth reporting requirements, as well as to measure progress against Commonwealth preschool education targets and reforms.

Scope: The scope of the ECE Annual Preschool Census included all children aged 0 to 6 years enrolled in a preschool program regulated and funded by NSW DoE. Services are required to give equal priority of access to children who are at least 4 years old on or before the 31 July in that preschool year and not enrolled or registered at a school; children who are at least 3 years old on or before 31 July and from low income or Aboriginal and/or Torres Strait Islander families; children with English Language needs; children with disabilities; children who are at risk of significant harm (from a child protection perspective). There is no order of priority assigned to the list above.

Coverage: Participation in the ECE Annual Preschool Census was mandatory for NSW Government-funded preschools. The collection included NSW Government-funded (but not necessarily NSW Government-run) preschool services, including preschools operated by Catholic and Independent schools, preschools operated by local governments, and community-managed preschools. Early childhood education programs not funded by the NSW Government, including some preschools delivered in non-government schools, were not in scope of the collection. These services are not excluded from applying for NSW Government funding, provided that they meet eligibility criteria, consistent with the objectives of universal access. As and when any of these services do enter into a funding agreement with the NSW Government under the Early Childhood Education Grants Program, they are thereafter required to participate in the ECE Annual Preschool Census.

The majority of preschool programs in NSW are delivered by commercial centre based day care (CBDC) providers that receive minimal, non-ongoing funding from NSW DoE. As a result, no data was collected from these services by the NSW Government as part of the ECE Annual Preschool Census. Data on commercial CBDCs were collected for the NECECC by the Australian Government DESE using the Child Care Subsidy System (CCSS).

Service providers that were registered for the Child Care Subsidy (CCS) were requested to provide information in the ECE Annual Preschool Census only for children who did not receive the CCB or the CCR.

Data collection methods: The 2021 ECE Annual Preschool Census used a unit record level (URL) collection methodology for children and service providers.

The ECE Annual Preschool Census is an annual collection and was undertaken in 2021 from 19 July to 27 August, with a reference period of 2 August to 13 August. A reference fortnight was adopted to reflect the preschool delivery model in NSW whereby delivery of a preschool education program can vary between weeks. Fortnightly data were converted to a one-week average to enable valid and reliable national comparisons.

During the 2021 representative fortnight, many services were affected by COVID-19 lockdowns. As these complex and extenuating circumstances were difficult to capture in the data collection, and may have also impacted the capacity of services to collect accurate data, certain data elements have been suppressed (see Deviation from NECECC Standards table).

The NSW DoE compiled, processed and validated the data before submitting it to the ABS in November 2021.

The Early Childhood Contract Management System (ECCMS) is the online system used by NSW DoE and service providers to manage preschool service contracts and funding.

There are four main sections to the census component of ECCMS:

• Service and location details (drawn from core ECCMS and not editable by users)
• Service location operating hours
• Individual child details, e.g. name, address, daily fees, low income status, enrolment and attendance
• Individual worker details, e.g. qualification field and level, main role, main work activity

Information on Aboriginal and/or Torres Strait Islander status was provided to the community preschool by a child's parent or carer in accordance with the record keeping requirements of the Education and Care Services National Regulations. Services were required to answer the question by selecting a single value from an on-screen drop down list. The values available for selection comprised the first 4 values of the NMDS as well as the supplementary value Not Stated to accommodate instances where the parent or carer did not provide this information to the Service.

Prior to data submission a user with a defined level of authority must enter a declaration that the entered data is correct. Following data submission NSW DoE undertook a data validation phase where submitted data were cross-checked for consistency with service operational characteristics and past submissions. Where large variations or unusual data was apparent, service providers were contacted to confirm data accuracy. If data was incorrect the census was reopened to allow the user to correct and resubmit data. All data validation rules were coded into SQL procedures, and NSW DoE maintained an anomalies database to track communications, and the status of potential errors.

Data collected for the NECECC in 2021 is broadly comparable with data collected in 2018, 2019 and 2020. In 2021, data items continued to be collected at the lowest (most granular) level of the service delivery hierarchy, i.e. service location (introduced in 2016).

An analysis of the coherence with other jurisdictional collections should be undertaken on an individual basis, considering data elements that are not consistent with the NECECC standards.

Deviations between the NECECC Standards and data collected from the ECE Annual Preschool Census are outlined in the below table. In 2021, COVID-19 resulted in several additional deviations.

NSW DoE provided a range of information and support to service providers throughout all stages of the collection. These included:

• regular emails to services in the lead up to and during the collection phase in 2021
• a dedicated census webpage providing summary information, portal access and links to resources and contact information

Detailed instructions on the process of data entry, including explanations and examples of concepts, were provided online within the application via summary 'tooltips' and extensive online help. NSW DoE also provided a separate ECE Annual Preschool Census Quick Reference Guide.

During the 6 week collection phase service providers could also contact a dedicated 1300 phone number and email for assistance.

Data sourced from the ECE Annual Preschool Census are published as part of Preschool Education, Australia and Microdata: Preschool Education, Australia on the ABS website.

Selected results from the census may be published in media releases, on the Department’s website and in Ministerial speeches, including in Parliament.

The 2021 NECECC data submission from the Victorian Department of Education and Training (Vic. DET) was sourced solely from the Kindergarten Information Management (KIM) system administrative data.

Victoria went into a Stage 4 lockdown due to Coronavirus (COVID-19) during the 2021 NECECC reference week. The lockdown lasted eleven weeks and heavily impacted the operation and workload of early childhood services. At the same time there were delays to the implementation of the new Vic. DET Kindergarten Information Management system which impacted data collection.

Due to this situation, the Victorian Department of Education and Training (Vic. DET) did not fully conduct the annual Kindergarten Census that forms part of Victoria’s NECECC submission in 2021.

Data that is missing from the 2021 NECECC submission is described in the Deviation from the NECECC Standards table.

Vic. DET was responsible for the KIM system data collection in 2021. Data were collected in accordance with Funding and Service Agreement requirements.

Data were collected through the KIM system to enable accurate funding provision and reporting of key data across the Victorian Preschool sector, as well as to collect data to meet national reporting requirements.

Scope: The scope of data collected in the KIM system included all children aged 3 to 6 years of age who were enrolled during the reference period in Vic. DET funded preschool programs for children in the year prior to school. For the first time in 2021 the data collected included three-year-olds who were enrolled in funded preschool programs in the year two years before school. This data was included in line with Victoria’s roll out of funded Three-Year-Old Kindergarten.

Coverage: Data was collected from all service providers with current Funding and Service Agreements with Vic. DET.

Funded services comprise the vast majority of preschool service providers in Victoria. A small number of centre based day care (CBDC) providers operating programs for children in the year before school were not funded by Vic. DET and as a result, no data were collected from these services.

Data collection methods: The KIM system uses a unit record level (URL) data collection methodology for children and service providers.

KIM is a live system and service providers are required to update service and enrolment data throughout the year. All service providers were requested to check their enrolment information was up to date in KIM prior to the reference week. The KIM data used in the NECECC submission was extracted from the system on 7 September 2021 and includes only children enrolled during the reference week (2 to 7 August 2021).

The Vic. DET compiled, processed and validated the data before submitting it to the ABS in December 2021.

Data was collected from services via Vic. DET's online KIM system. Services provided data through a workflow which included validation and completeness checks.

Victoria has used a URL collection methodology since 2011, which means data collected in 2021 is comparable with previous years to 2011.

An analysis of the coherence with other jurisdictional collections should be undertaken on an individual basis, taking in to account any data elements that are not consistent with the NECECC standards. Deviations between the NECECC standards and data collected from the KIM system are outlined in the table below.

Extensive explanatory information was provided in Vic. DET's online KIM system and on the DET website. If service providers required clarification about the collection, they were also able to contact their regional office or the KIM helpdesk.

Vic. DET provides information on funding criteria and data collection responsibilities in the publication 'The Kindergarten Guide', which is available on the Vic. DET website http://www.education.vic.gov.au/childhood/providers/funding/Pages/kinderfundingcriteria.aspx.

Data sourced from the KIM system in 2021 are published as part of Preschool Education, Australia and Microdata: Preschool Education, Australia on the ABS website.

Headline figures from the KIM data extracts are published in Vic. DET Annual reports, in Victorian budget papers and as part of the Report on Government Services on the Australian Government Productivity Commission website.

Selected data are published on the Victorian Child and Adolescent Monitoring System Portal.

The information contained within this report has been sourced from Vic. DET in consultation with the ABS.

In 2021, the Queensland Department of Education (Qld DoE) submission to the NECECC consisted of data from the annual Early Childhood Education and Care Services Census (ECECSC), which collected childcare enrolment data, workforce data, and preschool program and enrolment data.

The organisation responsible for the 2021 ECECSC is Qld Department of Education (Qld DoE). Data for the 2021 ECECSC were collected under the Education and Care Services Act 2013 (Qld), the Education and Care Service National Law 2011 (Qld) and the Education (General Provisions) Act 2006 (Qld).

Data collected from the ECECSC enables Qld DoE to report on a variety of matters, such as the performance of the preschool sector to the Qld and Australian Governments and the community. The data are used to provide evidence for policy and program development and planning and to monitor outcomes of early childhood initiatives such as the department's Workforce Action Plan and the implementation of the Education and Care Services National Law.

Scope: The 2021 ECECSC includes all children who were enrolled in a licensed or approved child care service or State-delivered preschool program provided by a government school or through distance education. This included children that were enrolled in centre based day care (CBDC), preschool, State-delivered preschool, Limited Hours Care, eKindy, State-delivered early childhood development programs, Family Day Care and School Aged Care Services at the time of the ECECSC.

Children aged 3 to 6 enrolled in a preschool program were considered in-scope for the ECECSC.

In 2021, the ECECSC was able to capture unit record data for a greater number of children aged 3 than in previous years. This was due to a change in collection methodology whereby funded services were asked to provide unit record data for all children enrolled in preschool at their service. Previously, many funded services only submitted summary level information for children aged 3.

Coverage: The 2021 ECECSC achieved a 100% coverage of all approved service providers in Queensland. This includes all funded and unfunded services.

Data collection methods: The 2021 ECECSC used a unit record level (URL) data collection methodology for funded approved programs. Data for unfunded CBDC programs was supplied separately to the ABS for the NECECC by the Australian Government Department of Education, Skills and Employment (DESE) from the Childcare Subsidy System (CCSS).

The ECECSC is an annual collection and in 2021 was undertaken in the week commencing 23 August 2021, with reference period 23 August to 29 August 2021. Fortnightly data were converted to a one-week average to enable valid and reliable national comparisons.

The Qld DoE compiled, processed and validated the data before submitting it to the ABS in November 2021.

Due to a lockdown in South East Queensland during the national reference period (2 August to 8 August), the ECECSC was delayed by three weeks and run with a reference week of 23 August to 29 August. Two services located on the Queensland/New South Wales border also did not operate during the collection period due to state border restrictions.

For the 2021 ECECSC, data were collected from service providers via an online survey tool.

As part of the internal validation process for 2021, Qld DoE included online guides as well as explanatory notes within the online census to assist service providers with definitions and responses. Edit checks were built into the online census, which ensured that valid data were supplied. Data supplied by service providers also underwent a range of validation and edit checks post enumeration to ensure that the information was complete, internally consistent and fell within fixed known parameters.

Since 2015, Qld DoE has required a response to the Indigenous Status question for preschool children. This has eliminated issues with missing data from some records from earlier years and significantly reduced instances of "unknown" values for this item.

An analysis of the coherence with other jurisdictional collections should be undertaken on an individual basis, considering data elements that are not consistent with the NECECC standards. There were no deviations between the NECECC standards and the ECECSC data collected.

Qld DoE provided a range of information to assist in the collection and reporting of data, such as explanatory notes for providers. Explanatory notes, together with printable copies of ECECSC collection forms for staff, were available from the Qld DoE website https://earlychildhood.qld.gov.au/about-us/publications-and-research/early-childhood-education-and-care-services-census

Data sourced from the 2021 ECECSC are published as part of Preschool Education, Australia and Microdata: Preschool Education, Australia on the ABS website. Data from the ECECSC are published on the Qld DoE website: https://qed.qld.gov.au/publications/reports/statistics/early-years.

The information contained within this report has been provided by the Qld DoE in consultation with the ABS. Further information is available at the Qld DoE website https://earlychildhood.qld.gov.au/about-us/publications-and-research/early-childhood-education-and-care-services-census.

In 2021, South Australia's Department for Education submission to the NECECC consisted of data from the Annual Census of Children's Services (ACCS).

The organisation responsible for the ACCS is South Australia's Department for Education.

Information gathered by the ACCS included patterns of service usage and characteristics of children and families. The data were required by the SA Government for forward planning and the analysis of needs and gaps in current service provision. The data from this collection also enables reporting across the SA preschool sector.

Scope: The scope of the 2021 ACCS included children aged 3 to 5 years who were enrolled and attending (or expected to attend) a government managed or government funded preschool service (including integrated centres with a child care service), or a funded preschool program operating in non-government child care centres or schools. Out of scope were preschool services that receive no funding for their preschool program from the South Australia's Department for Education.

Children who are of Aboriginal or Torres Strait Islander origin, and children and young people who are the subject of custody or guardianship order under the Children and Young People (Safety) Act 2017 (SA), are eligible under the department’s Preschool Enrolment Policy to commence a government managed or government funded preschool after their third birthday and are entitled to up to 480 hours of preschool in the two years before full-time school. These children have been included as in scope.

Some funded preschool programs operating in non-government child care centres or schools also provide preschool to 3 year old children. South Australia's Department for Education does not obligate these services to provide data for these children in the ACCS unless they are enrolled in a preschool program in their year before full time school and are receiving preschool funding from South Australia's Department for Education for these children. Any data received for 3 year old children from these non-government services (regardless of whether they are in their year before full-time school) in the ACCS was submitted in the NECECC.

Coverage: In 2021, the ACCS achieved full coverage of all government managed and government funded preschools, including Independent and Catholic schools with funded preschool programs, and funded non-government centre based day care providers with a preschool program.

Unfunded Independent and Catholic school managed preschool providers and centre based day care (CBDC) providers with no department funded preschool program are not invited to participate in the ACCS. There are a relatively small percentage of South Australian children who have received a preschool program delivered by one of these unfunded services.

Data collection methods: The 2021 ACCS used a unit record level (URL) data collection methodology for children and service providers.

The ACCS is an annual collection and in 2021 was undertaken on 6 August, with reference period of 2 August to 13 August 2021. This reference fortnight was adopted by the department to reflect the preschool delivery model in SA. Fortnightly data were converted to a one-week average to enable valid and reliable national comparisons.

South Australia's Department for Education compiled, processed and validated the data before submitting it to the ABS in November 2021.

In 2021, the ACCS collected data through the use of three systems, one for non-government preschool providers and two for department preschools. The Early Years System (EYS) and the Education Management System (EMS) are web-based preschool administration systems used by department preschools in SA. Non-government preschool providers that are funded by the department use the Non-Government Preschool Data System (NGPDS) to submit the data required for the ACCS.

The NGPDS has been developed as a web-based preschool data reporting system that serves the dual purpose of collecting data requirements for grant funding administration as well as to satisfy State and National reporting obligations. The EYS, EMS and NGPDS have been developed with the capability of importing data from other administrative systems (e.g. Child Care Subsidy Systems or CCSS) to reduce respondent burden and input error. The EYS, EMS and NGPDS have validation rules built in to ensure services are submitting accurate data that is compliant with the NECECC standards.

South Australia's Department for Education collated data collected from both systems using a data repository known as the Early Childhood Data System or Data Administration Centre (DAC). The DAC allows for Data Reporting and Analytics staff to administer a data collection and to run checks and validations on the data received from service providers. The DAC also performs sequential match coding for children enrolled in preschool across multiple services. Service provider details are stored and maintained in the Location Services System (LSS), from which data for the 2021 Collection were also obtained.

Indigenous students are identified by the department through the standard question "Is the child of Aboriginal or Torres Strait Islander origin?" on the Preschool Enrolment Form.

Most data collected through the 2021 ACCS were generally comparable with equivalent data in the 2014-2020 NECECC. Due to system developments and data improvements, some data may not be comparable to 2013 data. With the exception of 2013, these years were undertaken using similar URL data collection methodologies.

The Department preschools also transitioned to a single intake preschool enrolment policy in 2013, which impacted on counts in 2014. Children are entitled to 4 terms of preschool in the year before they start school as follows:

• if a child turns 4 before 1 May, they may start preschool in Term 1 in that year
• if a child turns 4 on or after 1 May, they are eligible to start preschool from the beginning of Term 1 in the following year

An analysis of the coherence with other jurisdictional collections should be undertaken on an individual basis, taking in to account any data elements that are not consistent with the NECECC standards. There were no deviations between the NECECC standards and data collected from the 2021 ACCS.

The department provided a range of information to assist in the reporting of data, such as the 2021 ACCS Booklet and Coding Instructions. Key material was provided in the form of manuals and fact sheets to support the correct interpretation and explanation of concepts. The NGPDS is an intuitive system and user training has been provided via a webpage that contains user guides, video tutorials, and ACCS instructions. A dedicated EYS/NGPDS Support Team was in place to support users with technical issues or queries with either the EYS or NGPDS and the Data Management and Reporting team were available to respond to any data related questions.

Data sourced from the ACCS are published as part of Preschool Education, Australia and Microdata: Preschool Education, Australia on the ABS website.

The information contained within this report has been provided by South Australia's Department for Education in consultation with the ABS. Further information is available on the Department's website https://www.education.sa.gov.au

In 2021, the Western Australia Department of Education (WA DoE) submission to the NECECC consisted of data from the WA August School Census.

The organisation responsible for the WA August School Census is the WA Department of Education (WA DoE). Data for 2021 were collected under the School Education Act 1999 (WA).

Scope: The scope of the preschool component of the WA August School Census consisted of children who were attending a preschool program within a government or non-government school, including community based preschools operating under provisions of the School Education Act 1999.

Coverage: Full coverage was achieved for all registered and funded schools (both government and non-government) and community-based preschools operating under provisions of the School Education Act 1999. As preschool programs provided in Centre based day care (CBDC) settings are not funded or regulated by WA DoE, these service providers were not included in the WA August School Census.

Data collection methods: The 2021 WA August School Census used a unit record level (URL) data collection methodology for children and service providers.

The WA August School Census is an annual collection and in 2021 was undertaken on 6 August. The reference period for all data was the two weeks ending 6 August.

The WA DoE compiled, processed and validated the data before submitting it to the ABS in November 2021.

Government and community preschools’ data were obtained through an administrative system, the Integris Student Information Database (SID) and a daily data harvesting process. The SID is the primary source of URL data for public schools. The SID data were uploaded into the WA DoE online Student Census System where the data were checked, verified and endorsed as accurate by each school principal. For non-government schools, child URL data was extracted from school enrolment records at the census date. Non-government schools uploaded URL data using a comma-separated value file to the WA DoE's online Student Census System.

Following the validation checks detailed below, government, non-government and community preschool data collected through the WA August School Census were then stored in the Student Census System data warehouse, and extracted for the purposes of the NECECC.

Internal validation processes for the WA August School Census occurred at three different points of the process. The WA DoE online Student Census System had a series of in-built validation rules, some of which required the school to edit data before continuing, while other rules generated warnings alerting the user to anomalies. A second set of validation processes were run by the WA August School Census team, using both routine and ad-hoc validation methods to examine data while it was assembled into working files. The third set of validation rules were built into the custom software which loaded the census data into the Student Census System data warehouse.

Data for the NECECC’s ‘Service provider organisation—early childhood education program delivered by a qualified teacher indicator’ data element are obtained using an annual Kindergarten Provision Survey that is conducted at the same time as the WA August School Census.

Indigenous students are identified at enrolment using a standard enrolment form question. The coding of the responses is as per the National Schools Statistics Collection (NSSC), i.e. 1 - 4, and 9 for not stated or inadequately described. Schools' student information systems do not allow valid entries other than prescribed. WA DoE is confident it achieves a very high level of accuracy of its Indigenous identification, with results showing a high level of concordance with other independent measures/estimates (e.g. ABS's ERPs for Aboriginal and Torres Strait Islander Australians).

This is attributed to a strong push within the WA school sector (in which most preschools reside) to address:

• learning needs of Aboriginal and Torres Strait Islander students
• Aboriginal Education Officer involvement in schools to liaise with local Aboriginal communities to assist them enrol their children where applicable
• a student-centred funding model in the WA public school system which provides a higher rate of funding for students (including those in preschool) who are Aboriginal or Torres Strait Islander students to address their needs.
• Schools' census data are also subjected to audit by the WA DoE

The 2021 data are fully comparable to the data collected in 2018, 2019 and 2020.

Other changes over time which affected the comparability include:

• From 2015, data about preschool hours enrolled and attended were each collected specifically for the reference week. In 2014, however, hours enrolled was collected in relation to a 'typical' week and hours attended was collected in relation to the reference week. Consequently, enrolled and attended hours data in 2014 were not fully consistent (e.g. there were some cases where attendance hours exceed enrolment hours or hours offered). The 2015 to 2021 data are not affected by this limitation.
• From 2015, maximum preschool program hours available were specifically for the reference week, rather than for a 'typical' week as used in 2014.
• In 2017, the ‘Child—hours of an early childhood education program received from qualified teacher/s indicator’ was collected for preschool students in WA government schools as part of a national trial.  The data were only collected in 2017.

Data from 2014 to 2021 about preschool enrolment and attendance hours are not comparable to 2013 data due to a materially different methodology:

• From 2014, URL data about preschool hours enrolled and attended were collected as part of the WA August School Census for all children enrolled at government, non-government and community-based preschools. This process replaced the less refined process used in 2013 that collected child attendance information in aggregated form through a series of questions in the Kindergarten Provision Survey. Attendance hours data from 2013 are therefore not comparable to attendance hours data in 2014 to 2021.
• From 2014, maximum preschool program hours available were collected from service providers via the Kindergarten Provision Survey rather than being derived from the number of hours enrolled by preschool students (used prior to 2014).

Due to WA policy on enrolment and attendance there may be an under-count of children enrolled in preschool. This is because in WA, a child is only considered to be enrolled if they were enrolled at the school and had either attended at least one half-day in the two weeks immediately preceding the WA August School Census day or were absent due to illness or extended holiday with a known return date before the end of the school term.

An analysis of the coherence with other jurisdictional collections should be undertaken on an individual basis, considering data elements that are not consistent with the NECECC standards. Deviations between the NECECC standards and data collected from the WA August Student Census are outlined in the table below.

For all schools, the collection instrument contained significant guidance and computation rules to prevent inconsistent responses in relation to prior data entries. WA DoE and non-government sector staff who assisted schools to complete the WA August School Census were trained to provide phone and email support through the WA DoE Customer Service Centre system.

Data are published as part of Preschool Education, Australia and Microdata: Preschool Education, Australia on the ABS website. Aggregated data are also available from the WA DoE website.

In 2021, the Tasmania Department of Education (Tas. DoE) submission to the NECECC consisted of data from the Tasmanian 2021 ECEC Data Collection.

The organisation responsible for the Tasmanian ECEC Data Collection was the Tasmanian Department of Education (Tas. DoE). Data for the 2021 Tasmanian ECEC Data Collection were collected under the Education Act 2016 (Tas.).

The data collected by Tas. DoE in the Tasmanian 2021 ECEC Data Collection were used to report on Tasmanian achievements against performance targets, as well as progress against Australian Government preschool education targets and COAG reforms. For preschools, the information obtained was also used in determining the funding of services by the Tasmanian government.

Scope: The scope of the preschool education component of the Tasmanian ECEC Data Collection consisted of all children enrolled in a preschool program in 2021. The Tasmanian ECEC Data Collection was managed in conjunction with the Tasmanian Catholic Education Office and Independent Schools Tasmania. This ensures preschool children at non-government schools are accurately represented.

Data for 3 year old children were included in the 2021 Tasmanian ECEC Data Collection if they were granted an exemption to start preschool before they turned 4 years old as at 1 January 2021. This exemption is granted if:

• the student is assessed as gifted, or
• the student was previously enrolled in a preschool program interstate in 2020 or 2021, to enable contiguous school education

Coverage: The Tasmanian ECEC Data Collection included all registered Tasmanian schools, which is defined as all Government, Catholic, and Independent schools, along with Education and Care providers registered as a school in Tasmania.

Data collection methods: The 2021 Tasmanian ECEC Data Collection was conducted using a unit record level (URL) data collection methodology for children and service providers.

The Tasmanian ECEC Data Collection is an annual collection and in 2021 was undertaken on 6 August 2021, with a reference period of 26 July to 6 August 2021. This reference fortnight was adopted to reflect the preschool delivery model in Tasmania. Fortnightly data were converted to a one-week average to enable valid and reliable national comparisons.

Tas. DoE compiled, processed and validated the data before submitting it to the ABS in November 2021.

Child level: The process of obtaining and processing data in Tasmania commenced with government service providers uploading information from each child enrolment form into the Tas. DoE student management system 'EduPoint' which stored the information in a data warehouse. The data warehouse contains in-built data quality checks that provide timely data feedback to schools. Data from the warehouse were then used to populate the Tasmanian ECEC Data Collection. Non government schools enter student, timetable, attendance and teacher information into a secured online application.

Service Provider level: The data of government and non-government service providers were reviewed and cleaned by Tas. DoE staff. This process included numerous system quality checks such as confirming student ages, hours enrolled, and verifying duplicate enrolments across schools. A declaration stage is included in the data collection application, which each principal was required to review and declare that all data were true and correct. This set of students became the authoritative dataset for the census date (6 August). Preschool data were extracted from this census application to match with all other data collated for this Collection. Extensive quality assurance occurred for the attendance and teacher qualification data, to ensure that data were consistent with other Tas. DoE data sources.

All teachers in Tasmania must be registered by the Teachers Registration Board of Tasmania. As a result of the registration process, some long-term teachers have teaching certification or relevant 3 year degrees. The registration process requires all long-term teachers to demonstrate, through teaching experience, that they meet the criteria for an equivalent 4 year degree standard. If a long-term teacher meets this criterion, the teachers are deemed to have a 4 year teaching qualification for registration purposes.

Some specific validation methods applied in the data collection application and by Tas. DoE included:

• data code compliance with the NECECC standards
• detection of inconsistent data coding, e.g. teachers with no qualifications and students with dates of birth outside expected date ranges, indicating coding errors
• comparisons of student enrolment counts with previous year data
• review of school summary tables by student data by various categories, i.e. Indigenous status, enrolment hours
• students in repeat years of preschool

Indigenous students are identified at enrolment in Tasmanian government schools using the national ACARA schools’ enrolment question: "Is the student of Aboriginal or Torres Strait Islander origin?" The responses available are: No; Yes, Aboriginal; Yes, Torres Strait Islander; or Yes, Aboriginal and Torres Strait Islander. If a student or family doesn't answer the question, then the response is "Not Stated".

For Non-government schools, the same question is asked, with available responses from the non-government Kinder enrolment system: Aboriginal but not Torres Strait Islander origin; Torres Strait Islander but not Aboriginal origin; Both Aboriginal and Torres Strait Islander origin; Neither Aboriginal nor Torres Strait Islander origin; and Not stated/inadequately described. Again if there is no response, it is coded as "Not Stated".

Finally, Tasmania undertakes significant quality assurance on the data to ensure correct coding. Overall student numbers are in line with expectations and each school is reviewed to ensure the question and responses are representative.

The Tasmanian ECEC Data Collection submission to the NECECC were comparable with data collected in 2013 to 2020, as all collections were undertaken using a consistent unit record level (URL) data collection methodology.

An analysis of the coherence with other jurisdictional collections should be undertaken on an individual basis, taking into account any data elements that are not consistent with the NECECC standards. Deviations between the NECECC standards and data collected from the 2021 Tasmanian ECEC Collection are outlined in the table below.

To support data custodians participating in the Tasmanian ECEC Data Collection, a guide was sent to service providers to assist users with the data collection system. 

Data sourced from the Tasmanian ECEC Data are published as part of Preschool Education, Australia and Microdata: Preschool Education, Australia on the ABS website. 

Government student Kinder numbers are published in the Tasmanian Department of Education’s Annual report.

In 2021, the Northern Territory Department of Education (NT DoE) submission to the NECECC consisted of data from the Age/Grade Census.

The 2021 Age/Grade Census consisted of three components:

• Student Census
• Staff Census
• Preschool Census (Students and Staff).

The organisation responsible for the Age/Grade Census is the Northern Territory Department of Education (NT DoE). Data for the Census were collected under the Education Act (NT) 2016.

Data collected from the Age/Grade Census enables reporting on NT schools and the preschool sector for a variety of reporting requirements. The preschool data collected from the Age/Grade Census is used for the Supplementary Recurrent Assistance Enrolment Data Collection, the Report on Government Services (RoGS), National Partnership Agreements, government budget paper estimates and the NT DoE annual report.

Scope: The scope of the preschool component of the Age/Grade Census includes all children enrolled in preschool who have attended a government or registered non-government preschool at least once during the 4 week reference period 12 June - 6 August 2021 (the reference period did not apply during the NT school holidays 28 June - 19 July 2021). Two remote schools operate on different school terms and had the reference periods 21 June to 30 July and 14 June to the 20 August respectively.

In the NT, children are eligible to enrol in preschool at the beginning of the year if they turn 4 years of age on or prior to 30 June of the same year. Children in very remote schools may be enrolled in a preschool program when they turn three years of age, provided they will be accompanied by a parent who will remain with them for each session. This is an important strategy to engage children in remote areas in early childhood education programs.

Coverage: All government and registered non-government preschools participated in the Age/Grade Census. While the data collection methodology used for non-government preschools differed from that applied to government preschools, the data collected were at the same level of detail and are comparable with data from government preschools.

Centre based day care providers that deliver preschool programs were not within scope for the Age/Grade Census. For the purpose of the NECECC, the Australian Government Child Care Subsidy System (CCSS) was used for coverage of this sector.

Data collection methods: The 2021 Age/Grade Census used a unit record level (URL) data collection methodology for children and service providers.

The Age/Grade Census is an annual collection and in 2021 was undertaken on 6 August. The four-week reference period of 12 June – 6 August 2021 was used to determine which children are to be included in the collection. For the two schools operating on different school terms the reference period was 21 June to 30 July and 14 June to 20 August respectively.
 

Subsequently, the preschool data is converted to a two-week reference period (26 July – 6 August 2021); for instance, their hours offered is calculated over the two-week reference period not the four-week reference period. Their attendance is calculated over the week including Friday 6 August. Fortnightly data were converted to a one-week average to enable valid and reliable national comparisons.

The NT DoE compiled, processed and validated the data before submitting it to the ABS in November 2021.

Child level data: In 2021, data extracts from the Student Census record level information were submitted from each government and some non-government schools' Student Administration and Management System (SAMS). Non-government schools without SAMS provided child, teacher and service provider record level information via Excel spread sheets. Additional data for staff and preschool (students and staff) were collected through an online survey tool for government schools. All data was processed centrally for inclusion in the Age/Grade census collection.

It should be noted that seasonal attendance patterns for the NT show lowest attendance during August. This is partially due to sporting and community events and the transient lifestyle of remote and very remote populations.

After data were processed by NT DoE, school principals were required to check the data, edit if necessary, and confirm accuracy. Business rules guided the processing of data. All three components of the Age/Grade Census required formal sign-off from school principals for the final data lodgement, stating it was a true and accurate representation of their school for the reference period. This ensured the quality and validity of the data being provided. Internal validation of the early childhood data was subsequently undertaken.

Detailed validation processes used by NT DoE in 2021 were as follows:

• school validation: schools were provided with a validation report and were required to confirm the information was correct. Schools were required to carry out validation reporting to maintain data quality, targeting such areas as child Aboriginal and Torres Strait Islander status, gender and age
• system validation: the validation process included historical comparison of trends, comparison of enrolments and schooling level proportions, cross checking missing data and application of national reporting rules

Students’ Indigenous status is identified through the enrolment form. Government schools use the following question:
 

Where no answer is recorded, schools are asked to follow up with the parent/guardian to confirm the Indigenous status of the child. This is done throughout the year and forms part of the validation process for the Age/Grade Census. Students without a valid Indigenous status are flagged in validation reports. If the parent/guardian does not wish to disclose the Indigenous status it is recorded as Not Stated.

Non-government schools are not required to use the same enrolment form as government schools so the wording may vary slightly. 

Data collected through the 2021 Age/Grade Census were comparable with data collected in 2019 and 2020. These collections were undertaken using a consistent URL data collection methodology.

An analysis of the coherence of this collection with other jurisdictional collections should be undertaken on an individual basis, taking into account any data elements that are not consistent with the NECECC standards.

Deviations between the NECECC standards and data collected from the Age/Grade Census are outlined in the table below.

The NT DoE provided a range of information to service providers to assist in the collection and reporting of data, such as manuals and fact sheets, to support correct interpretation and definition of concepts. Detailed reports and instructional papers on the requirements, processes and rules for submitting data through the Age/Grade Census were provided to service providers to assist with data provision.

Data sourced from the Age/Grade Census are published as part of Preschool Education, Australia and Microdata: Preschool Education, Australia on the ABS website.

The Age/Grade Census preschool data is also available via the NT DoE’s annual report and NT Department of Treasury and Finance Budget Papers Agency KPIs. The data is summarised and excludes centre based day care.

In 2021, the ACT Education Directorate (the Directorate) submission to the NECECC consisted of data from the August ACT Public Schools Census and Independent schools.

Data for the 2021 census were collected under the Education Act 2004 (ACT), the Children and Young People Act 2008 (ACT), and the ACT Childcare Services Standards 2009.

Scope: The scope of the preschool component sourced from the ACT Public School Census included all children between 4 and 6 years of age attending public preschools. It is ACT policy that preschool is only provided to 4 and 5 year olds and this policy has been applied more strictly since 2016, resulting in no/zero 3 year olds being included in the collection except Koori children and 3 year old Accelerated Entry - Gifted and Talented children enrolled in the year before full time schooling for 15 hours per week.

Children enrolled in a preschool program at Jervis Bay School were included in the census as that school is administered by the ACT Education Directorate on behalf of the Australian Government. Children who were absent for more than 4 continuous school weeks prior to the census date were included if the principal received written documentation signed by the child's guardian indicating that the child would return to school.

Coverage: Full coverage for 2021 was achieved for all ACT Government managed schools.

Data collection methods: The 2021 ACT Public School Census used a URL data collection methodology for children and service providers.

In August each year, the Directorate conducts a census of public school enrolments. The ACT Public School Census was conducted on Friday 6 August, with a reference period of 30 July to 12 August 2021. Fortnightly attendance data were converted to a one-week average to enable valid and reliable national comparisons.

The ACT Education Directorate compiled, processed and validated the data before submitting it to the ABS in October 2021.

Child level data: On 6 August 2021, the ACT public schools enrolment data was captured from the school administration system (SAS) and cross checked with schools for accuracy. Individual child information was captured from data supplied via an enrolment form which was entered in the student administration system (SAS) by school staff. The principal of each school was required to sign off on their school's total enrolment count by sex and year level. Any inconsistencies were followed up for correction.

Key approaches undertaken by the ACT to manage the quality of its data processing for 2021 are as follows:

• ACT's system included automatic edits and mandatory fields, such as date of birth, sex, family details, attendance status and Indigenous status
• ACT cross checked addresses for the preschools ensuring one existed for each service provider
• child addresses were geo-coded to produce valid SA1 codes and MB

The ACT carried out validation of 2021 data in several ways, including but not limited to:

• manual data entry was avoided where possible through an automatic transfer of child information when the child had previously attended another ACT public school
• date of birth was checked against year level and outliers were followed up
• duplicate records of one child attending two schools were followed up
• data checks included matching back to the original census data and running aggregate counts for each field

To meet reporting requirements for the two-week reference period, child level attendance data was extracted from a new student administration system which is in the process of implementation. Care should be taken when comparing this data with data from previous years and from other jurisdictions.

Service provider level data: The process of obtaining service provider information from public preschools in the ACT was managed through the school administrative system.

Data collected through the 2021 preschool components of the ACT Public School Census were comparable with data collected in 2020, as both collections were undertaken using a consistent URL data collection methodology.

An analysis of the coherence with other jurisdictional collections should be undertaken on an individual basis, taking into account data elements not consistent with the NECECC standards. There were no deviations between the NECECC standards and the data collected from the ACT Public School Census.

ACT Preschools were notified of the data collection through the ACT Education Directorate intranet. The Directorate provided government schools with a manual to assist users with the ACT Public School Census module, including instructions and validation techniques.

Data sourced from the ACT Public School Census are published as part of Preschool Education, Australia and Microdata: Preschool Education, Australia on the ABS website. School-level preschool enrolment counts are reported in the ACT Public School Census publication.

The organisation responsible for the ACT Independent Preschool Collection was the ACT Education Directorate in collaboration with the Association of Independent Schools of the ACT. Data for 2021 were collected under the Education Act 2004 (ACT), the Children and Young People Act 2008 (ACT), and the ACT Childcare Services Standards 2009.

Scope: The scope of the early childhood education component of the ACT Independent Preschool Collection included all children attending a preschool program in an Independent school. It is ACT policy that preschool is only provided to 4 and 5 year olds and this policy has been applied more strictly since 2016 resulting in very low counts for 3 and 6 year olds. Children who were absent for more than 4 continuous school weeks prior to the census date were included if the principal received written documentation signed by the child's guardian indicating that the child would return to school.

The scope for data provided on workers included all paid primary contact teachers that delivered a preschool program and other contact and administrative school staff employed during the reference period at Independent schools in ACT.

Coverage: The 2021 ACT Independent Preschool Collection included the primary Independent schools delivering a preschool program.

Data collection methods: The 2021 ACT Independent Preschool Collection collected data using a URL data collection methodology for children and service providers.

The ACT Independent Preschool Collection is an annual collection with a reference period of 2 August 2021 to 13 August 2021. Fortnightly data were converted to a one-week reference period to enable valid and reliable national comparisons.

The ACT Education Directorate compiled, processed and validated the data before submitting it to the ABS in October 2021.

In 2021, the Directorate carried out validation of 2021 data from each Independent school delivering a preschool program. Service provider information for Independent preschools in the ACT was provided by each of the Independent Schools, either through this collection or via the Child Care Benefit System.

ACT Independent Schools most commonly collect the indigenous status of students through the school's enrolment process. It is the family's decision if they wish for the student to be identified or not in the enrolment process or at any other time during the student's schooling.

This is the 9th year the data for ACT Independent preschools has been included in the National ECEC Collection. The data has been collected on a comparable basis to 2020. There were no deviations between the NECECC standards and data collected.

In 2021, the data was collected by the Directorate directly from the Independent schools in collaboration with the Association of Independent Schools of the ACT. The Directorate liaised closely with the Director of the Association of Independent Schools of the ACT and the best contact person of each school to verify details. The Directorate then worked with each participating Independent school to collect the data.

Data sourced from the ACT Independent Preschool Collection for the 2021 National ECEC Collection are published as part of Preschool Education, Australia and Microdata: Preschool Education, Australia on the ABS website.

The Directorate collected information contained in this report directly from Independent schools in consultation and collaboration with the Association of Independent Schools of the ACT.

In 2021 the Catholic Education Office of the Archdiocese of Canberra and Goulburn submission to the NECECC consisted of data from the ACT Catholic Preschool Collection.

The organisation responsible for the ACT Catholic Preschool Collection was The Catholic Education Office of the Archdiocese of Canberra and Goulburn. Data for 2021 were collected under the Education Act 2004 (ACT), the Children and Young People Act 2008 (ACT), and the ACT Childcare Services Standards 2009.

Scope: The scope of the preschool component of the ACT Catholic Preschool Collection included all children between 4 and 5 years of age attending a preschool program in a Catholic school. Children who were absent for more than 4 continuous school weeks prior to the census date were included if the principal received written documentation signed by the child's guardian indicating that the child would return to school.

Coverage: The 2021 ACT Catholic Preschool Collection included all primary Catholic schools delivering a preschool program or programs.

Data collection methods: The 2021 ACT Catholic Preschool Collection used a unit record level (URL) data collection methodology for children and service providers.

The ACT Catholic Preschool Collection is an annual collection and in 2021 was undertaken on 6 August, with a reference period of 26 July to 6 August 2021. Fortnightly data were converted to a one-week average to enable valid and reliable national comparisons.

Catholic Education compiled, processed and validated the data before submitting it to the ABS in November 2021.

In 2021, data were obtained from a point in time sweep of enrolment and attendance data stored in the ACT Catholic School administration system (known as 'MAZE'). Catholic Education carried out validation of 2021 data using data from the MAZE administrative system and through consultation with Catholic Education personnel and service providers. Data from each Catholic school delivering a preschool was assessed by Catholic Education.

Indigenous students are identified at enrolment, through the enrolment form. The information is not mandatory. Data is collected and stored in the MAZE administration system.

The 2021 ACT Catholic Preschool Collection was the 9th time Catholic preschool data were included in the NECECC. An analysis of the coherence with other jurisdictional collections should be undertaken on an individual basis, taking in to account any data elements that are not consistent with the NECECC standards. There were no deviations between the NECECC standards and data collected in the ACT Catholic Preschool Collection.

In 2021, the majority of data were collected by MAZE sweeps and Human Resources Employment extracts, cross checked with personnel at Catholic Education and Centres. Catholic Education liaised closely with the Director of each centre to verify details.

Data sourced from the ACT Catholic Preschool Collection are published as part of Preschool Education, Australia and Microdata: Preschool Education, Australia on the ABS website.

The information contained within this report has been provided by the ACT Education Directorate and Catholic Education Office in consultation with the ABS. Further information is available from the ACT Education Directorate website http://www.det.act.gov.au.

Scope: The scope for data provided on workers included all paid primary contact teachers and school learning support officers delivering preschool programs at government schools in NSW. Only primary contact teachers were considered in-scope for the National ECEC Collection.

Data collection methods: The 2021 Government Schools Census collected data using a URL data collection methodology for the following statistical entities:

• Worker - data at the worker record level.

All NSW Department of Education (DoE) government school-based preschools were required to participate in the Government School Census by completing an online census form. There were three sections to the preschool component of the Government School Census, the third of these relates directly to the collection of worker data:

• Teacher data (e.g. qualifications and length of employment).

For more information about child and service data, please refer to Appendix 3 - Jurisdictional data quality statements within this publication.

Scope: The scope for data provided on workers included all paid workers employed in service providers that were regulated and funded by NSW DoE.

Data collection methods: The 2021 ECEC Preschool Census collected data using a URL data collection methodology for the following statistical entity:

• Worker - data at the worker record level.

There are four main sections to the census component of Early Childhood Contract Management System (ECCMS), the fourth of these relates directly to the collection of worker data:

• Individual staff details, e.g. qualification field and level, main role, main work activity.

For more information about child and service data, please refer to Appendix 3 - Jurisdictional data quality statements within this publication.

Scope: The scope for data provided on workers included all paid primary contact teachers and educators employed in the services in scope.

Data collection methods: The 2021 Kindergarten Census collected data using a Unit Record Level (URL) data collection methodology for the following statistical entities:

• Worker - data at the worker record level.

Data was collected via the Department of Education and Training (DET) online Kindergarten Information Management System (KIMS).

Services provided data for the 2021 Kindergarten Census through a workflow which included validation and completeness checks.

The worker data was impacted by the following in 2021:

• Data was collected for the first time via the new KIMS which may have impacted continuity for some datasets.
• Throughout 2021, Victorian services were heavily impacted by COVID-19 lockdowns and related staffing issues.

The teacher count in 2021 was higher than expected based on historical data.  Possible reasons for this are: inconsistent data entry during 2020 and 2021 due to COVID-19; additional staff employed in 2021 to cover leave or provide extra support during the pandemic; and improved data collection prompts in the new system.

There was a higher level of missing data within records in 2021 and educator records were not collected for 181 services. Where possible, information has been supplemented with data held in the previous Kindergarten Information Management system.

For more information about child and service data, please refer to Appendix 3 - Jurisdictional data quality statements within this publication.

Scope: The scope for data collected on workers through the Early Childhood Education and Care Services Census (ECECSC) included all staff, both paid and volunteer engaged in approved or licensed child care services. Only staff who delivered or supported the delivery of a preschool program were considered in-scope for the Collection.

Data collection methods: The 2021 ECECSC collected data for approved programs using a URL data collection methodology for the following statistical entities:

• Worker - data at the worker record level.

For more information about child and service data, please refer to Appendix 3 - Jurisdictional data quality statements within this publication.

Scope:  The scope of data provided on workers included all paid workers employed in government managed or government funded preschool providers, including integrated centres, and funded non-government child care centres and schools with a preschool program. Data on workers includes workers who are usually present to deliver a face to face preschool program but may have been absent due to illness or extended holiday and are expected to return.

Several non-government service providers delivering a preschool program submitted worker data for staff employed as child care workers, which was out of scope of the collection. These out-of-scope records were not easily identifiable and have been submitted in the NECECC.  Worker data collected from non-government services did not include fields for the person (employed) including the hours worked in delivering an early childhood education program, the workers ID and the worker’s name and date of birth to facilitate a record linkage key field being created.

Data collection methods: The 2021 ACCS collected Unit Record Level (URL) data for the following statistical entities:

• Worker: data at the worker record level

For more information about child and service data, please refer to Appendix 3 - Jurisdictional data quality statements within this publication.

Scope: The scope for data provided on workers included all paid educators (teachers and education assistants) who work for at least one hour per week in the active delivery of preschool programs at all government, Catholic and Independent schools, and community-based preschools operating under provisions of the School Education Act 1999. The worker data did not include teacher-qualified school principals or other school administrative staff who may have contributed to, or quality assured, preschool provision in the school.

Data collection methods: The 2021 WA August School Census collected data using a Unit Record Level (URL) data collection methodology for the following statistical entities:

• Worker - data at the worker record level.

All educators (teachers and education assistants and Aboriginal and (WA) Islander Education Officers) who work with kindergarten children for more than one hour per week were required to provide details on their field and level of highest qualification relevant to ECEC. If an educator had no qualifications, they were required to indicate whether they were currently working towards an ECEC qualification and also whether they have seven or more years of experience in teaching preschool (the first year of school, known as ‘kindergarten’ in WA, and offered part-time) or Pre-primary (the first year of full-time school in WA). To be registered as a teacher in WA, teachers are required to produce evidence they are four year trained or equivalent. Equivalency is determined by the Teacher Registration Board of Western Australia.

For more information about child and service data, please refer to Appendix 3 - Jurisdictional data quality statements within this publication.

Scope: The scope for data provided on workers included all paid and unpaid contact workers that were employed in Government, Independent and Catholic schools during the reference period and were involved in service provision of a preschool program.

Data collection methods: The Tasmanian 2021 ECEC Data Collection collected data using a Unit Record Level (URL) data collection methodology for the following statistical entities:

• Worker - data at the worker record level.

Teacher data were collected directly from the Tasmanian ECEC Workforce application. Qualification information for teachers and principals was collected from the Teachers Registration Board of Tasmania.

All non-teacher worker qualification data were collected directly from Government, Independent and Catholic schools, as the government data warehouse does not hold non-teacher data centrally.

If a worker holds more than one qualification, the following rules applied:

• the highest ECE qualification was reported for the worker if applicable;
• in instances where the worker did not hold an ECE qualification, then the highest teaching related qualification was reported;
• in instances where the worker did not hold a teacher qualification, the highest non-teaching related qualification was reported.

All teachers in Tasmania must be registered by the Teachers Registration Board of Tasmania. As a result of the registration process, some long-term teachers have teaching certification or relevant 3 year degrees. The registration process requires all long-term teachers to demonstrate, through teaching experience, that they meet the criteria for an equivalent 4 year degree standard. If a long-term teacher meets this criterion, the teachers are deemed to have a 4 year teaching qualification for registration purposes.

Extensive quality assurance occurred for the attendance and teacher qualification data, to ensure that data were consistent with other Tas. DoE data sources.

For more information about child and service data, please refer to Appendix 3 - Jurisdictional data quality statements within this publication.

The 2021 Worker dataset’s completeness may be slightly impacted due to COVID-19 impacts, due to unavailability of some workers to complete the collection during September 2021. 

It is estimated that less than 2% of workers data was not included, based on the number of workers reported in previous data collections.

Scope: The scope for data provided on workers included all paid workers employed in government and registered non-government preschools and who were registered with the NT Teacher Registration Board. Workers were included irrespective of whether they delivered a preschool program during the reference period.

Data collection methods: The 2021 Age/Grade Census collected data using a Unit Record Level (URL) data collection methodology for the following statistical entities:

• Worker - data at the worker record level.

Additional data for staff and preschool (students and staff) were collected through an online survey tool for government schools. All data was processed centrally for inclusion in the census collection.
Teachers were required to provide details on their field of highest qualification relevant to early childhood education and care. NT DoE considered all teachers registered with the NT Teacher Registration Board as four year equivalent qualified teachers.

For more information about child and service data, please refer to Appendix 3 - Jurisdictional data quality statements within this publication.

Scope: The scope for data provided on workers included all paid primary contact teachers and teaching assistants that delivered or helped to deliver a preschool program during the reference period at public schools in the ACT.

Data collection methods: The 2021 ACT Public School Census used a Unit Record Level (URL) data collection methodology for the following statistical entities:

• Worker - data at the worker record level.

Children are included in the Aboriginal and Torres Strait Islander counts if they are identified by a parent or guardian as being of Aboriginal and/or Torres Strait Islander origin.

An estimate of the number of preschool program hours a child may have been enrolled/attending during the calendar year. It is calculated as a child's hours enrolled/attending in the reference week, multiplied by the number of weeks their service provider(s) operated in the calendar year.

For the purposes of this publication, a child is considered to be attending a preschool program if the child was enrolled and present for at least one hour during the reference period. Children who did not attend a preschool program during the reference period (e.g. children who were absent due to illness or extended holiday leave) are not considered to have attended a preschool program.

A child is considered to be enrolled if they were offered a place, formally enrolled or registered in the preschool program and:

• attended the preschool program for at least one hour during the reference period, or
• were absent during the reference period due to illness or extended holiday leave, but were expected to return.

A child is not considered to be enrolled if they were absent during the reference period and not expected to return to the preschool program.

An episode is the count of the occurrence of a specific characteristic. For example, a preschool episode refers to a preschool program provided to a child. When one child attends two different preschool programs, the child is attending two episodes of preschool.

Estimated Resident Population is the official measure of the population of Australia and is based on the concept of usual residence. It refers to all people, regardless of nationality, citizenship or legal status, who usually live in Australia, with the exception of foreign diplomatic personnel and their families. It includes usual residents who are overseas for less than 12 months. It excludes overseas visitors who are in Australia for less than 12 months. Estimates of the Australian resident population by state and territory are generated on a quarterly basis by adding natural increase (the excess of births over deaths), Net Interstate Migration, and Net Overseas Migration occurring during the period to the population at the beginning of each period. Note that population figures included in this publication are preliminary and based on the 2016 Census. For more information, see the Explanatory Notes section of this publication, National, state and territory population and Regional Population by Age and Sex.

Fees refer to the actual tuition fees charged for the child to attend a preschool program after subsidies have been deducted.

The Index of Relative Socio-Economic Disadvantage (IRSD) used in this release was developed by the ABS and ranks areas in Australia according to most disadvantaged to least disadvantaged using variables from the 2016 Census of Population and Housing. A low score on this index indicates a high proportion of relatively disadvantaged people in an area. It cannot be concluded that an area with a very high score has a large proportion of relatively advantaged people, as there are no variables in the index to indicate this.

See Aboriginal and Torres Strait Islander children.

Preschool management type refers to the legal or social entity responsible for managing the delivery of a preschool program. The management type categories include the following:

Government managed

• state and territory and local government managed: Services that are managed by the state, territory or local government. Excludes state and territory government schools
• state and territory government schools: Schools that are funded and managed by the respective state or territory government

Non-government managed

• private not-for-profit - community managed: Services that are managed by organisations based in the community through a membership made up of community members (e.g. the parents). The membership elects a management committee and the committee is accountable to the membership. No profit is distributed to the management committee or the members, and any surplus funds are redirected to the service.
• private not-for-profit - other organisations: Services that are managed by non-profit organisations such as charity organisations, consortium of charity organisations and church groups. Excludes Independent and Catholic schools
• private for-profit: Services provided or managed by a company or private individual
• independent schools: Non-government schools that are governed, managed and accountable at the level of the individual school and are not affiliated with the diocesan Catholic Education Office
• Catholic schools: Schools that are affiliated with the diocesan Catholic Education Office
• other: Other services include employer sponsored services
   

A preschool program is a structured, play-based learning program, delivered by a degree qualified teacher, aimed at children in the year or two before they commence full-time schooling. This is irrespective of the type of institution that provides it or whether it is government funded and/or privately provided. Preschool programs are often referred to by other terms such as early childhood education, early learning or kindergarten.

A degree qualified early childhood teacher who meets the requirements of the National Quality Framework for Early Childhood Education and Care (the National Quality Framework). The Australian Children’s Education and Care Quality Authority (ACECQA) publishes a list of approved and former approved early childhood teaching qualifications.

Remoteness areas divide Australia into broad geographic regions on the basis of their relative access to services. They are based on the Accessibility/Remoteness Index of Australia (ARIA) which measures the remoteness of a point based on the physical road distance to the nearest Urban Centre.

Sector is a classification derived from the service activity type and management type characteristics of service providers.

The service activity type is the main type of service available from or provided by a service provider. Service activity types include:

• Centre based day care (CBDC): A centre based day care service (known as long day care prior to 2 July 2018) is a centre based form of child care service providing all-day or part-time care for children (services may cater to specific groups within the general community). For-profit and not-for profit organisations, local councils, community organisations and employers may run these services. CBDC primarily provides services for children aged 0-5 years. Some centre based day care may also provide early childhood education and kindergarten programs and care for school children before and after school and during school holidays, where state and territory government regulations allow this. The service may operate from stand-alone or shared premises, including those on school grounds.
• Early childhood education program: Comprises services providing a structured, play-based learning program, aimed at children in the year or two before they commence full-time schooling. The terms most commonly used to describe early education programs which are subject to the National Partnerships Universal Access to Early Childhood Education (UANP) in states and territories are:
   
  • Kindergarten – Queensland, Western Australia, Tasmania
  • Kindergarten or Preschool – Victoria, South Australia
  • Preschool – New South Wales, Northern Territory, Australian Capital Territory
     

SEIFA is a product developed especially for those interested in the assessment of the welfare of Australian communities. SEIFA is a suite of four summary measures that have been created from 2016 Census information. The indexes can be used to explore different aspects of socio-economic conditions by geographic areas. The SEIFA index used in this publication is the Index of Relative Socio-economic Disadvantage (IRSD).

The state-specific year before full-time schooling (YBFS) population is made up of an age range of children specific to each state based on that state’s preschool and school starting age provisions.

Unit record level data collections contain data for each individual statistical entity in a collection population.

Workers include an early childhood education and care worker who is employed, and paid, by an early childhood education and care service provider as a principal/director/coordinator/teacher-in-charge, group leader/teacher, assistant/aide or other contact worker to plan and deliver or support the delivery of an early childhood education program (excludes non-contact workers). A contact worker may be employed on a contract, part-time or full-time basis.

Preschool Education, Australia is compiled with data from the National Early Childhood Education and Care Collection (NECECC). This collection is derived from administrative data provided by state and territory and Australian Government education departments and the Catholic Education Office of the Archdiocese of Canberra and Goulburn.

The impacts to the early childhood education and care (ECEC) sector from COVID-19 to the services delivering a ‘quality’ education program have not changed the underlying concepts of the data collected in the National Early Childhood Education and Care Collection (NECECC) for 2021. Jurisdictions were provided with clarifying statements to ensure that enrolment and attendance data in an early childhood education program included online or remote learning, in addition to the usual face-to-face delivery.

A comprehensive quality declaration for each jurisdiction can be found in Appendix 3 – Jurisdictional data quality statements.

This publication is partly conducted to support performance-based reporting for the National Partnership Agreement on Universal Access to Early Childhood Education – 2018–2021. It aims to compile child and service provider statistics from all service providers delivering an in-scope preschool program within Australia.

The National Early Childhood Education and Care Collection population includes:

• service providers providing a structured, play based learning program, delivered by a degree qualified teacher, aimed at children in the year or two before full-time schooling (a preschool program) during the reference period
• children between 3 and 6 years of age (inclusive) at 1 July who were enrolled in a preschool program during the reference period - to be considered enrolled, the child must have attended the preschool program for at least one hour during the reference period, (including attended an early childhood education program online or remotely due to COVID-19 impacts), or be absent due to illness or extended holiday leave or due to COVID-19 impacts and expected to return
• all paid employees who had direct contact with children at a service provider during the reference period. Paid contact workers must have delivered or assisted in delivering a preschool program during the reference week. 

The National Early Childhood Education and Care Collection has been conducted annually since 2010. The census date for the collection is the first Friday in August each year. Some jurisdictions may adopt a 2 week reference period that needs to include the census week. In exceptional circumstances a different reference period may be used if agreed to by the Australian Department of Education, Skills and Employment, the jurisdiction and the Australian Bureau of Statistics.

A summary of jurisdictional collection reference periods can be found in Appendix 3 – Jurisdictional data quality statements.

Data for the National Early Childhood Education and Care Collection have been compiled according to national standards outlined in the Early Childhood Education and Care National Minimum Data Set in order to maximise consistency of data across the various jurisdictions. Alignment with these standards has not been completely achieved by all jurisdictions, and care should be taken when comparisons across jurisdictions are made. In addition, some jurisdictions were not able to provide the ABS with certain data elements as specified in the national standards.

Data quality overall is determined by the data submissions. Data issues are described in the Explanatory Notes of this publication, and in Appendix 3 – Jurisdictional data quality statements.

Further information on the Early Childhood Education and Care National Minimum Data Set is available on the Australian Institute of Health and Welfare website.

Due to jurisdictional differences in coverage, collection methodologies and alignment with the Early Childhood Education and Care National Minimum Data Set standards, the data presented in this iteration of Preschool Education, Australia may not be directly comparable across all jurisdictions or with previous years.

Differences in the scope and counting rules for the National Early Childhood Education and Care Collection mean that the data presented in the publication are not strictly comparable to data published in other national or state/territory publications.

National Early Childhood Education and Care Collection: Concepts, Sources and Methods contains detailed information on the data sources, terminology and other technical aspects associated with early childhood education and care statistics.
