TIMSS 2023

Trends in International Mathematics and Science Study 2023

TIMSS 2023 marks the eighth cycle of the international mathematics and science assessment since the inauguration of the study in 1995. Providing over 20 years of trend data, TIMSS has been a valuable tool for monitoring international trends in mathematics and science achievement at the fourth and eighth grades.

Like the previous TIMSS assessments, TIMSS 2023 will collect detailed information about curriculum and curriculum implementation, instructional practices, and school resources. A new feature of TIMSS 2023 will be an innovative, group adaptive design that allows for a better alignment of the assessment with the student populations in the participating countries.

The TIMSS & PIRLS International Study Center at the Lynch School of Education, Boston College, United States, serves as the international study center for TIMSS 2019, working in close cooperation with the IEA, and the national centers of participating countries.

Why participate in TIMSS 2023?

TIMSS achievement data are accompanied by a rich array of contextual questionnaire data about how countries around the world deliver and improve learning in mathematics and science. Trend results across study cycles permit countries to monitor the effectiveness of their educational systems in a global context.

The 2023 cycle presents countries with the unique opportunity to participate in TIMSS and IEA’s International Computer and Information Literacy Study (ICILS) at the same time. The parallel data collection of both studies in 2023 will enable participating entities to gain a more holistic understanding of educational outcomes: whereas ICILS measures computer literacy skills of students, TIMSS uses a computer-based assessment to assess mathematics and science achievements. Participating in both studies will enable countries to relate these educational outcomes. In addition, the burden for countries to participate in two IEA studies can be minimized and synergies can be strengthened. For more information, see ICILS 2023.
