The IEA DPC assists study participants with their national databases and prepares the international database for each study.
Data from IEA Studies
Fifty years of IEA research have resulted in a wealth of data on numerous aspects of international education. There are a number of resources available to support researchers interested in secondary analysis of IEA data. The data are managed by the IEA Data Processing and Research Center (DPC) and are available free of charge.
IEA Study Data Repository
Data and documentation files from a number of completed IEA studies are available online at the IEA Study Data Repository. The studies include CIVED, ICCS 2009, PIRLS (2001, 2006, 2011), prePIRLS 2011, the Reading Literacy Study (for countries that administered the test in both 1991 and 2001), SITES (Module 1, 2006), TIMSS (1995, 1999, 2003, 2007, 2011), and TIMSS Advanced (1995, 2008). Data from ongoing studies will be added after the release of the respective international databases.
Data from IEA studies before 1995
Data from several IEA studies conducted before 1995 have been made available online through the University of Gothenburg's COMPEAT research program in the Department of Education and Special Education. The studies include FIMS, Six Subject Survey (science (FISS), reading comprehension, literature education, English as a foreign Language, French as a foreign language, and civic education), SIMS, SISS, and the Reading Literacy Study.
IEA IDB Analyzer (New version 3.1)
Download the installation guide: Installing the IDB Analyzer (Version 3.1) (~0.4 MB)
The IEA International Database (IDB) Analyzer is an application developed by the IEA DPC to facilitate the analysis of data from IEA's large-scale assessments, such as TIMSS, PIRLS, and SITES. It creates SPSS code that can be used with SPSS to conduct statistical analyses, taking into account the complex sample structure of the databases.
The software allows you to combine data from different countries for cross-country analysis and to select specific subsets of variables. It provides several different procedures for analysis, such as the computation of means or percentages of any background variable of interest for a whole country or subgroup within a population.
IEA Data Visualizer
The IEA Data Visualizer is a Flash Player-based application adapted by the IEA DPC to provide interactive visualizations which facilitate the interpretation of information from the IEA TIMSS and PIRLS studies. This is displayed by means of a world or regional map and by a selection of graphs.
In particular, it allows trends to be visualized over time, by either playing as an animation or by scrolling the study year manually.
This software is meant to provide an overview of the IEA study results. For clarity the results are shown without indication of standard errors. Not all differences that can be seen are statistically significant. Users may use tools such as the IEA IDB Analyzer to estimate the correct standards and to apply tests of significance.
The IEA Data Visualizer manual is available here.
NCES International Data Explorer and training modules
Developed by the National Center for Education Statistics (NCES), the International Data Explorer allows you to explore data from TIMSS and PIRLS. The NCES Distance Learning Dataset Training system provides online training modules in the use of TIMSS and PIRLS data.
Other resources for researchers working with IEA data include:
- IERI training academies, offered regularly to help statisticians and researchers develop expertise in the use of large-scale international databases;
- conferences to foster collaboration and knowledge sharing of research findings related to IEA studies;
- awards for high-quality empirical research that makes use of IEA data.
