TIMSS 2023 Encyclopedia Release

The TIMSS 2023 Encyclopedia: Education Policy and Curriculum in Mathematics and Science is now available at https://timss2023.org/encyclopedia. The Encyclopedia is an overview of the diverse educational systems of TIMSS 2023 participating countries and benchmarking entities, providing valuable context for interpreting the TIMSS 2023 International Results in Mathematics and Science.

Sixty-four countries and 8 benchmarking participants administered TIMSS 2023, and each contributed a chapter to the Encyclopedia describing their education system and their mathematics and science curricula. Additionally, representatives from each education system completed the TIMSS 2023 Curriculum Questionnaires. Data from these questionnaires are presented in an interactive format where users can explore topics such as policies on school entry and promotion, teacher and principal preparation, and coverage of the TIMSS 2023 mathematics and science topics in education systems’ curricula. Together, the chapters and curriculum questionnaire data enable a greater understanding of the national contexts in which students around the world learn mathematics and science.
