Enrollment is open for TIMSS 2027

Enrollment is open for the ninth cycle of the international mathematics and science assessment. Since 1995, TIMSS (Trends in International Mathematics and Science Study) has been at the forefront of monitoring international trends in mathematics and science achievement across fourth and eighth-grade students. This latest cycle brings with it new and exciting developments based on decades of experience in international large-scale student assessment.

State-of-the-art digital assessment

TIMSS 2027 is a fully digital assessment that employs state-of-the-art methods to create engaging assessments in mathematics and science. TIMSS 2027 integrates more authentic item types beyond traditional multiple-choice questions and other traditional formats, allowing students to demonstrate deeper understanding and critical thinking.

Expanded coverage

TIMSS 2027 expands coverage in mathematics and science by improving how we measure skills at different levels of achievement, ensuring a comprehensive view of student achievement across populations and over time. The mathematics and science assessment frameworks are updated each cycle to reflect the participating countries’ current curricula, standards, and frameworks, as well as research and policy priorities.  

Contexts for learning mathematics and science

TIMSS 2027 aims to capture not only academic achievement, but also valuable data that helps contextualize that achievement for educators, researchers, and policymakers. The study gathers information about the contexts for learning mathematics and science from participating students, their teachers, and their school principals, as well as data about the mathematics and science curricula in each country.
