DATA ITEM LISTS

The Program for the International Assessment of Adult Competencies (PIAAC) comprised a questionnaire, and a set of assessments. The questionnaire contained 11 modules and approximately 330 questions, which resulted in approximately 380 data items.

Users intending to purchase a CURF should consult the data item list to ensure that the data they require, and the level of detail they need, are available in the product.

The PIAAC Basic and Expanded CURF files contain 8,600 confidentialised respondent records aged 15 to 74 years. The PIAAC Basic CURF (International Comparison version) contains 7430 confidentialised respondent records aged 16 to 65 years. Subject to the limitations of the sample size and the data classifications used, it is possible to interrogate the CURF, produce tabulations and undertake statistical analyses to individual specifications.

CURF Data

The Basic CURF file contains approximately 310 data items and the Expanded CURF file contains approximately 340 data items. The Basic CURF (International Comparison version) contains approximately 1330 data items, however not all data items contain data. This CURF contains empty data items where additional data may be available for other countries that participated in PIAAC in the OECD's Public Use File (PUF). For a complete list of all data items included on the Basic and Expanded CURFs, including relevant population and classification details, refer to the Excel spreadsheets in the Downloads tab. The data item spreadsheets have 14 worksheets:

  • table of contents
  • population descriptions (Expanded CURF only)
  • data items on demography
  • data items on background information
  • data items on education
  • data items on work
  • data items on work characteristics
  • data items on skill use at work
  • data items on literacy, numeracy and information and communications technology (ICT) use at work
  • data items on literacy, numeracy and information and communications technology (ICT) use in everyday life
  • data items on self perception and wellbeing
  • data items on income
  • plausible values
  • identifiers and weights
  • data items on workflow (Basic CURFs only).

The populations used in the derivations of the data items are listed in the Population column of each data item.

Comparison between the Basic and Expanded CURFs

The differences between the Australian Basic and Expanded CURFs are listed in an Excel spreadsheet available from the Downloads tab. Note that the identifiers for some data items differ between the Basic and Expanded CURF due to the differences in the presentation of data items. Therefore, caution should be exercised if using both the Basic and Expanded CURF. The differences to the Basic CURF (International Comparison version) are not documented in the spreadsheet. A full list of data items on the Basic CURF (International Comparison version) can be found in a separate Excel spreadsheet available from the Downloads tab.

The key differences between data items in the Australian Basic and Expanded CURF are:
  • the Expanded CURF includes derived population items
  • the Expanded CURF includes additional items in areas such as demographic, education, employment and income
  • the Expanded CURF occupation and industry items use ANZSCO and ANZSIC classifications, whereas the Basic CURF uses ISCO and ISCED classifications
  • the Expanded CURF includes the level of the plausible values
  • the Expanded CURF does not include items related to the workflow of the survey
  • the Basic CURF includes workflow data items.

The 2011-2012 PIAAC Basic CURF is distributed on a single CD-ROM and the PIAAC Basic CURF (International Comparison version) is electronically distributed. The PIAAC Expanded CURF is distributed via RADL and ABSDL.

The populations used in the derivations of the data items are listed in the Population column of each data item.
