Trends in International Mathematics and Science Study

NCES has added data from the 2019 administration of the Trends in International Mathematics and Science Study (TIMSS) to the International Data Explorer (IDE). The IDE is an online, interactive tool that allows users to explore international study data and create customized tables, charts, maps, and analyses. TIMSS is an international comparative study that measures trends in fourth- and eighth-grade mathematics and science achievement every 4 years. New data include TIMSS 2019 results for mathematics and science scales and subscales, as well as contextual data from the student, teacher, and school questionnaires. These new 2019 data are available for the United States and about 60 other participating countries and education systems across six continents. The TIMSS IDE now includes data from all seven administrations of TIMSS (1995, 1999, 2003, 2007, 2011, 2015, and 2019). Start exploring the TIMSS data in the IDE at: https://nces.ed.gov/surveys/international/ide/. For more information about TIMSS, visit the website at: https://nces.ed.gov/timss/. TIMSS is coordinated internationally by the International Association for the Evaluation of Educational Achievement (IEA) and managed in the United States by NCES at the Institute of Education Sciences, part of the U.S. Department of Education. The IDE is a product of NCES.
