TIMSS 2027 marks the ninth cycle of the international mathematics and science assessment—conducted every four years—since the inauguration of the study in 1995. Providing trend data for over three decades, TIMSS is a digital assessment that captures an accurate picture of fourth- and eighth-grade students' mathematics and science achievement and contextual data about their learning experiences.
The TIMSS & PIRLS International Study Center at Boston College, serves as the international study center for TIMSS 2027, working in close cooperation with IEA, and National Study Centers of participating countries.
- Curriculum-based frameworks for assessing mathematics and science achievement
- Computer-based assessment engaging students through innovative tasks
- Policy-relevant information on contexts of learning mathematics and science
- Group adaptive assessment design to ensure engagement and alignment with student populations
- Enhanced international reporting to explore results interactively
By participating in TIMSS 2027, countries can contribute to shaping the future of education by empowering students, educators, and policymakers with data-driven insights. Participants receive a comprehensive set of data and publications:
- TIMSS 2027 Frameworks
- National datasets (achievement and context questionnaire data)
- TIMSS 2027 Encyclopedia describing national contexts for teaching and learning mathematics and science
- Internationally comparable results with infographics and interactive report tables
- Open Access International Database, including student process data variables, and User Guide
- Methods and Procedures technical documentation
- TIMSS Insights reports highlighting research topics using TIMSS data
In TIMSS 2027, it is possible to re-assess the same students one year after the TIMSS 2027 assessment to investigate students’ learning gains over one year of schooling. This longitudinal option enables examining the degree of increases across instructional goals and the differences in gains across subgroups of students.
