TIMSS Advanced 2015 International Database

The TIMSS Advanced 2015 International Database is available to all individuals interested in the data collected and analyzed as part of TIMSS Advanced 2015. The aim is to support and promote the use of these data by researchers, analysts, and others interested in improving education. A public use version of the database is available for download using the links below. For the TIMSS Advanced 2015 assessment, the database includes student achievement data for two subjects, advanced mathematics and physics, as well as the student, teacher, school, and curricular background data for the 9 participating countries. The student, teacher, and school data files are in SAS and SPSS formats. The entire database and its supporting documents are described in the TIMSS Advanced 2015 User Guide for the International Database (Foy, 2017) and its three supplements. The data can be analyzed using the downloadable IEA IDB Analyzer (version 4.0), an application developed by the IEA Data Processing and Research Center to facilitate the analysis of the TIMSS data. A restricted use version of the TIMSS Advanced 2015 International Database is available to users who require access to variables removed from the public use version (see Chapter 4 of the User Guide). Users who require access to the restricted use version of the International Database to conduct their analyses should contact the IEA through its Study Data Repository.
