Microdata from the Programme for the International Assessment of Adult Competencies (PIAAC) survey are available as Basic CURFs and an Expanded CURF. The microdata on the Basic and Expanded CURF provide scores from exercises completed by respondents age 15-74 years, except for the Basic CURF (International Comparison version) which provides scores by respondents aged 16-65 years, to assess their literacy, numeracy and problem solving in a technology-rich environment skills, as well as a range of demographic data and information on educational attainment and skill use at work and in everyday life.
The level of detail provided is shown in the data item lists. The data item list for the Basic CURFs and Expanded CURF can be found by clicking on the Downloads tab of this product.
PIAAC was conducted throughout Australia from October 2011 to March 2012. It is the most recent survey of Adult Competencies conducted by the ABS, with the Adult Literacy and Life Skills (ALLS) survey conducted in 2006 and the Survey of Aspects of Literacy (SAL) survey in 1996.
The microdata contain finer levels of detail of data items than what is otherwise published in other formats, for example in Programme for the International Assessment of Adult Competencies (PIAAC), 2011-2012 (cat. no. 4228.0). For more information on the level of detail provided, please see the associated data item lists.
Steps to confidentialise the data made available on the CURFs are taken in such a way as to maximise the usefulness of the content while maintaining the confidentiality of respondents selected in the survey. As a result it may not be possible to exactly reconcile all the statistics produced from the microdata with other published statistics. Further information about the steps taken to confidentialise the microdata is available through the following link: About CURF Microdata.
Data previously released for ALLS and SAL are not directly comparable with PIAAC data due to;
Remodelled scores from ALLS and SAL are also included in data cubes available from the Downloads tab of the publication Programme for the International Assessment of Adult Competencies (PIAAC), 2011-2012 (cat. no. 4228.0).
PIAAC expands on the previous surveys by assessing skills in the domain of 'problem solving in technology-rich environments'. This domain is a new edition to PIAAC and is not comparable to the problem solving scale derived in ALLS.
New data items in PIAAC collected information about skill use and practices at work, including:
Caution is advised when comparing results from ALLS and SAL with data from PIAAC. While the re-modelled data should facilitate comparability over time, analysis undertaken by the ABS and internationally has shown that in some cases the observed trend is difficult to reconcile with other known factors and is not fully explained by sampling variability. For more information see the Explanatory Notes section of Programme for the International Assessment of Adult Competencies (PIAAC), 2011-2012 (cat. no. 4228.0). Also see the PIAAC Explanatory Notes (cat. no. 4228.0) for information on the comparability of the surveys with other ABS surveys.
Australian data was also published in an international report released by the OECD on 8 October 2013, compiling the results of the 24 countries that participated in the first round of PIAAC. This report also included time series data for countries who participated in the previous iterations of PIAAC. The report and other outputs from the survey are available from the OECD website at www.oecd.org/site/piaac/.
