Question of the Month:

Is there special software to use to analyze PIAAC data?

A: You can use SAS, Stata, SPSS programs, or an online tool to analyze PIAAC data. The OECD, in collaboration with international partners, has developed SAS and Stata macros to incorporate PIAAC complex sampling and assessment designs.  SPSS macros were developed by the Data Processing and Research Center of the International Association for the Evaluation of Educational Achievement (IEA-DPC) and are in a form of a free add on software called the IDB Analyzer that generates SPSS syntax for analysis. To do basic analysis, you can use the International Data Explorer (IDE), a user-friendly, online tool. The NCES IDE can be found here and the OECD IDE can be found here.  An explanation of the differences between the NCES IDE and OECD IDE can be found on the NCES IDE homepage. For more information on PIAAC data and to access the IDB Analyzer or SAS and Stata macros, go here.
