What is TIMSS?

The Trends in Maths and Science Study, known as “TIMSS”, is an international comparative study that assesses and compares the performance in maths and science of pupils at age 10, or Year 5 in Wales, every four years across about 60 countries. It provides internationally comparative data on pupils’ achievement in maths and science, and how their performance is related to their attitudes, gender and background. In addition, TIMSS includes questionnaires for teachers, headteachers and parents/carers, which provide a valuable perspective on teaching maths and science, and the school and home environment.
