International Cross-Time, Cross-System Database

XTXS is a comprehensive source of education-related data from both IEA and non-IEA studies.

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, ICILS 2013, 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, the 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.

Additional Opportunities

Additional opportunities 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.
