EXPLANATORY NOTES

INTRODUCTION

1 This publication contains statistics on children enrolled and attending preschool programs across Australia in 2017. The statistics were compiled from data collected through the National Early Childhood Education and Care Collection (the Collection). The Collection includes data about service providers and children. Data on workers were included in some previous cycles of the Collection and were sought for 2017 but were sometimes incomplete or not yet available. Accordingly, statistics on workers have not been included in this publication, however may be available on request at a later date.


PRESCHOOL PROGRAM

2 For the purposes of the Collection, a preschool program is defined as a structured, play based learning program, delivered by a degree qualified teacher, aimed primarily 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 or privately provided.

3 A preschool program can be delivered in a variety of settings such as stand-alone preschools, preschools co-located as part of a school (both government and non-government), and within a Long Day Care (LDC) centre. A child may attend both a preschool and a separate or adjoined child care facility, such as family day care, outside school hours care, vacation care, in-home care and occasional care services. Participation in preschool is not compulsory and is influenced by parental preference and other factors, such as school starting age in the particular jurisdiction.
Preschool programs are referred to by a variety of other terms across state and territories. Age entry requirements also differ across states and territories. These differences are summarised in the following table:

PROGRAM TERMINOLOGY AND AGE ENTRY REQUIREMENTS, by State and Territory - 2017
Jurisdiction	Preschool program		Transition to primary school Foundation year (Year prior to year 1)
	Program	Age of entry	School year	Age of entry
New South Wales (a)	Preschool	Generally 4 and 5 year olds	Kindergarten	5 by 31 July
Victoria (b)	Kindergarten	4 by 30 April	Preparatory (Prep)	5 by 30 April
Queensland	Kindergarten	4 by 30 June	Preparatory (Prep)	5 by 30 June
Western Australia	Kindergarten	4 by 30 June	Pre Primary	5 by 30 June
South Australia (c)	Preschool	4 by 1 May	Reception	5 by 1 May
Tasmania	Kindergarten	4 by 1 January	Preparatory	5 by 1 January
Australian Capital Territory	Preschool	4 by 30 April	Kindergarten	5 by 30 April
Northern Territory (d)	Preschool	4 by 30 June	Transition	5 by 30 June

Jurisdiction notes:
(a) New South Wales subsidises early access to community preschool for 3 year old Aboriginal children and 3 year old children from low-income families. In New South Wales, all licensed children’s services for under 6 year olds (who have not commenced Kindergarten) are required to offer programs that meet children’s educational and developmental needs.
(b) In Victoria, Aboriginal and Torres Strait Islander children and children known to child protection are eligible for free kindergarten through Early Start Kindergarten funding if they are aged 3 by 30 April of the year in which they are enrolled.
(c) South Australia provides early access to Department funded preschool for children who are Aboriginal or under the Guardianship of the Minister after their 3rd Birthday. The compulsory school starting age in South Australia is 6 years at the oldest.
(d) In the Northern Territory, children living in very remote areas can attend preschool from the age of three, provided a parent/guardian accompany the child and remain with them at each session until they reach the age of three years and six months.

SCOPE AND COVERAGE

4 The scope of the Collection consists of all service providers delivering a preschool program to children aged 3 to 6 years (inclusive) enrolled during the reference period.

Service Provider
5 A service provider is considered to be in-scope if it was providing 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 (a preschool program) during the reference period.

Child
6 All children who as at 1 July in the collection year were between 3 and 6 years of age (inclusive) and were enrolled during the reference period in a preschool program are in-scope of the Collection. To be considered as enrolled, the child must have attended the preschool program for at least one hour during the reference period, or be absent due to illness or extended holiday leave and expected to return.

7 In an effort to achieve comprehensive coverage, data were sourced from the Australian Government, state and territory education departments and the Catholic Education Office of the Archdiocese of Canberra and Goulburn. The data are mainly sourced from administrative collections, supplemented where necessary to improve the coverage of service providers not otherwise captured due to funding, regulation or licensing arrangements. The coverage in each state and territory for the 2017 Collection is described in Appendix 3 - Jurisdictional Data Quality Statements (available in the second stage of release).


DATA COMPARABILITY

8 To ensure national comparability, all jurisdictions were required to follow national data standards. The Early Childhood Education and Care National Minimum Data Set (ECEC NMDS) is a set of national data standards which has been established by the Australian Institute of Health and Welfare (AIHW), in conjunction with the ABS, the Department of Education and Training, and state and territory departments responsible for early childhood education. More information on the ECEC NMDS can be found on the AIHW website.

9 Not all jurisdictions were able to align their collection methods precisely with these standards as described in Appendix 3 (available in the second stage of release). Issues affecting data comparability between the states and territories are included as footnotes and/or explanatory notes within this publication.


LONG DAY CARE CENTRE DATA

10 For the 2017 Collection, information on preschool programs delivered in Long Day Care (LDC) settings was primarily provided by the Australian Government from the Child Care Management System (CCMS), through which all services approved for the purposes of administering Child Care Benefit (CCB) are obliged to provide data.


COLLECTION DATE AND REFERENCE PERIOD

11 The Collection date is the first Friday in August of each year. The census date for the 2017 Collection is Friday 4 August 2017, with the 1 week reference period spanning 31 of July to the 6 of August 2017. Some jurisdictions may adopt a 2 week reference period that includes the census week. This means the permissible period spans the 24 of July to the 13 of August 2017 inclusive. Jurisdictional collection dates and reference periods for 2017 are summarised in the table below.

MEASUREMENT CONCEPTS

12 Jurisdictions collect and report data for the Collection using a Unit Record Level (URL) collection methodology. A URL methodology collects information for individual children and service providers. A URL collection is the most appropriate method for ensuring a child who is enrolled in multiple preschool programs is only counted once in child level estimates.

Episodes
13 For the Collection, an episode is a single occurrence of a child enrolled in and/or attending a preschool program. When a child attends two different preschool programs, this is described as a child having two attendance episodes.

Unique Child Counts
14 The unique child count ensures that when a child attends two or more different preschool programs, the child is only counted once. In any given collection year, the number of unique children will be expected to be less than their number of preschool episodes.

Year Before Full-Time Schooling (YBFS)
15 The YBFS population takes into account the preschool and school entry provisions of the state in which the child usually resides (see Explanatory Note 3) and the child’s date of birth. As part of deriving this state-specific YBFS population, an adjustment has been applied to certain cohorts for both New South Wales and Victoria to account for a greater than 12 month YBFS period and the rates at which it is estimated that children are likely to proceed from preschool to school education in those states. The adjustments are based on estimates from the state education departments and are:
· The NSW YBFS cohort is made up of the sum of children born 2 July 2011 - 31 December 2012 and a share of children born 1 January 2013 - 31 July 2013 (the share for this group is 56%, which is the proportion estimated to commence full-time schooling in the following year).
· The Victoria YBFS cohort includes children born 2 July 2011 - 31 December 2012 and a share of children born in January 2013 - April 2013 (the shares for these groups are 74% for January 2013, 63% for February 2013, 52% for March 2013 and 41% for April 2013 which are proportions estimated to commence full-time schooling in the following year).


PRESCHOOL PROGRAM FEES

16 Fee schedules can differ between programs, organisations and jurisdictions. Fees may be charged daily, weekly, annually, per session or per term. If data is collected at any level other than weekly, the weekly fee is derived from the collected fee and fee schedule. Fees charged are usually based on the number of hours of a preschool program a child is enrolled to receive.

17 Information on fees is collected at the episode level. Where a child has more than one preschool episode, their fees are calculated by summing the fees for all of their episodes.

18 Data on fees are rounded to the nearest dollar for publication.


HOURS

19 For URL data, information on hours is collected at the episode level. Where a child has more than one episode at a preschool program their hours are calculated by summing the hours for all of their episodes.

20 Data on hours are rounded to the nearest hour for publication. Hours less than 1 but more than 0 are rounded to 1 hour.


ESTIMATED RESIDENT POPULATION (ERP)

21 The preliminary ERP figures presented in this publication are published numbers based on the 2016 Census. The ABS has provided these numbers as indicative only. They have been included here to support comparative reporting that has been performed using the 2016 ERP time series. In the Collection, children enrolled and attending preschool programs in Jervis Bay have been included in statistics for the ACT. The Other Territories of Christmas Island and Cocos (Keeling) Islands have been included in statistics for WA. Norfolk Island has been included in statistics for NSW. Official ERP numbers for WA, ACT and NSW do not include Other Territories.

CLASSIFICATIONS

22 Statistics in this publication are presented according to Sector, Statistical Geography and Socio-Economic Indexes for Areas (SEIFA).

Sector

23 The Sector classification used in this publication is a combination of the service provider characteristics Service Activity Type and Management Type, which are part of the ECEC NMDS. Where a child is enrolled in multiple preschool programs, the child’s sector is determined by the characteristics of all the providers at which the child was enrolled.

24 Tables presented with this classification assign episodes and unique child counts to states and territories according to the geographic location of the service provider.

Statistical Geography

25 For the 2017 Collection, data have been classified to the 2011 Australian Statistical Geography Standard (ASGS) standard. The ASGS has been updated based on results from the 2016 Census; however the updated 2016 Socio-Economic Indexes for Areas (SEIFA) will not be released until later in 2018. To ensure consistency across the publication the 2011 ASGS standard has been retained for the 2017 collection.

26 The digital boundaries, codes and labels for each of these regions can be downloaded from the ABS website free of charge.

27 The Remoteness Structure within the ASGS divides each state and territory into areas on the basis of their relative access to services. The classes of Remoteness Area (RA) are:
· Major Cities of Australia
· Inner Regional Australia
· Outer Regional Australia
· Remote Australia
· Very Remote Australia
· Migratory - Offshore - Shipping
· No usual address.

28 For more information please refer to the online publication: Australian Statistical Geography Standard (ASGS): Volume 5 - Remoteness Structure, July 2011 (cat. no. 1270.0.55.005).

29 There are two sets of statistics presented using RAs in this publication. The RA of the child’s main service provider is used, as well as the RA of the child’s usual residence. Where a child’s usual residence is not stated, their main service provider’s geography is used as a proxy. If the service provider’s geography is also not stated, the child’s RA may be imputed where possible and otherwise included only in the totals. It is possible for states or territories to have a zero count in a certain RA class; Tasmania does not contain a Major City, the Northern Territory does not contain a Major City or an Inner Regional classification, and ACT does not contain Remote or Very Remote classifications.

30 The quantity of records for which RA was derived, using service provider geography, can be identified from the Not Stated SEIFA IRSD data.

31 The ASGS Local Government Areas are an ABS approximation of gazetted local government boundaries as defined by each State and Territory Local Government Department. The 2016 edition of the Local Government Areas (LGAs) structure has been used in the collection. For more information, see Australian Statistical Geography Standard (ASGS): Volume 3 - Non ABS Structures, July 2016 (cat. no. 1270.0.55.003).

32 The ASGS Indigenous Structure provides a geographical standard for the publication of statistics about the Aboriginal and Torres Strait Islander population of Australia. The 2011 edition of the Indigenous Structure has been used in the collection. For more information, see Australian Statistical Geography Standard (ASGS): Volume 2 - Indigenous Structure, July 2011 (cat. no. 1270.0.55.002).

33 The ASGS Commonwealth Electoral Divisions are an ABS approximation of Australian Electoral Commission (AEC) electoral division boundaries. The 2016 edition of the Commonwealth Electoral Divisions (CED) structure has been used in the collection. For more information, see Australian Statistical Geography Standard (ASGS): Volume 3 - Non ABS Structures, July 2016 (cat. no. 1270.0.55.003).

34 ASGS State Electoral Divisions are an ABS approximation of the respective State and Territory Electoral Commission's state electoral districts. The 2016 edition of the State Electoral Divisions (SED) structure has been used in the collection. For more information, see Australian Statistical Geography Standard (ASGS): Volume 3 - Non ABS Structures, July 2016 (cat. no. 1270.0.55.003).

Socio-Economic Indexes for Areas

35 The 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 2011 Census of Population and Housing information. For each index, every geographic area in Australia is given a SEIFA number which shows how disadvantaged that area is compared with other areas in Australia. Quintiles are calculated by ordering the scores for all areas from lowest to highest, with the lowest 20% of areas given a quintile number of 1 and so on, up to the highest 20% of areas which are given a quintile number of 5. The indexes provide more general measures of socio-economic status than is given by measuring, for example, income or unemployment alone. The SEIFA index used for the Collection is the Index of Relative Socio-economic Disadvantage (IRSD). Where a child’s geography was not stated, the SEIFA IRSD is published as Not Stated.

36 For more information on SEIFA please see the Information Paper: An Introduction to Socio-Economic Indexes for Areas (SEIFA), 2006 (cat. no. 2039.0).


CONFIDENTIALITY

37 The Census and Statistics Act 1905 provides the authority for the ABS to collect statistical information, and requires that statistical output shall not be published or disseminated in a manner that is likely to enable the identification of a particular person or organisation. This requirement means that the ABS must ensure that any statistical information about individuals cannot be derived from published data.

38 To minimise the risk of identifying individuals in aggregate statistics, a technique is used to randomly adjust cell values and summary variables. This technique is called perturbation. Perturbation involves small random adjustment of the statistics and is considered the most satisfactory technique for avoiding the release of identifiable statistics while maximising the range of information that can be released. These adjustments have a negligible impact on the underlying pattern of the statistics.

39 After perturbation, a given published cell value will be consistent across all tables. However, adding up cell values to derive a total will not necessarily give the same result as published totals.

40 Applying perturbation in this publication ensures that these statistics are consistent with statistics released via services such as TableBuilder.
