NCES 2022047 Trends in International Mathematics and Science Study (TIMSS) 2019 U.S. public-use data files and documentation
The TIMSS 2019 U.S. public-use data files and documentation include the following at grades 4 and 8: student, teacher, and school data in ASCII text format; SPSS and SAS control files for reading the ASCII data to produce SPSS and SAS data files; codebooks; illustrative merging code; a Read Me file; and a Quick Guide. Also included for each of the grades are the analogous files for the Bridge study, which was conducted to form a link between eTIMSS countries’ computer-based data in 2019 and their paper-based data in 2015 as well as to the paper-based TIMSS countries in 2019. The TIMSS 2019 U.S. public-use student, teacher, and school data files include U.S. specific variables that are not part of the U.S. data files in the IEA’s TIMSS 2019 international database. They are add-on files that do not contain weight variables or replicate weights, and therefore must be merged with the U.S. data files in the IEA’s public-use international database before any analysis can be conducted. The U.S. data files in the IEA’s public-use international database can be downloaded at https://timss2019.org/international-database/. Users of this data should consult the U.S. Technical Report and User Guide for the 2019 Trends in International Mathematics and Science Study (TIMSS) available for viewing and downloading at https://nces.ed.gov/pubsearch/pubsinfo.asp?pubid=2022049.

NCES 2022048 Trends in International Mathematics and Science Study (TIMSS) 2019 U.S. restricted-use data files and documentation
The TIMSS 2019 U.S. restricted-use data files and documentation include the following at grades 4 and 8: student and school data in ASCII text format; SPSS and SAS control files for reading the ASCII data to produce SPSS and SAS data files; codebooks; illustrative merging code; a Read Me file; and a Quick Guide. Also included for each of the grades are the analogous files for the Bridge study, which was conducted to form a link between eTIMSS countries’ computer-based data in 2019 and their paper-based data in 2015 as well as to the paper-based TIMSS countries in 2019. The TIMSS 2019 U.S. restricted-use student and school data files include U.S. specific variables that are not part of the TIMSS 2019 U.S. public-use data files or the U.S. data files in the IEA’s TIMSS 2019 public-use international database. They include NCES school IDs that facilitate merging with the Common Core of Data (CCD) for public schools and the Private School Universe Survey (PSS) for private schools. They are add-on files that do not contain weight variables or replicate weights, and therefore must be merged with the U.S. student and school data files in the IEA’s public-use international database before any analysis can be conducted.
