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
