TIMSS 2023

The Trends in International Mathematics and Science Study (TIMSS) is an assessment of mathematics and science performance that has been monitoring global trends in pupil attainment at Years 5 and 9 since 1995. TIMSS takes place every 4 years in over 60 countries; it provides internationally-comparable data about performance and how this relates to pupils’ attitudes, gender and background. TIMSS also includes surveys of teachers and school leaders to gather information about their views on teaching and resources for mathematics and science.
