TIMSS 2015 International Database
The TIMSS 2015 International Database is available to all individuals interested in the data collected and analyzed as part of TIMSS 2015.

For the TIMSS 2015 eighth grade assessment, the database includes student mathematics and science achievement data as well as the student, teacher, school, and curricular background data for the 39 participating countries and 6 benchmarking entities.

The student, parent, teacher, and school data files are in SAS and SPSS formats.
The entire database and its supporting documents are described in the TIMSS 2015 User Guide (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.
