The Programme for International Student Assessment (PISA) is the world’s largest international study of education systems, developed by the Organisation for Economic Cooperation and Development (OECD). Every three years, PISA tests 15-year-old pupils from all over the world in science, mathematics and reading. By participating in PISA25 you are contributing to improvements to education in the UK and beyond. More information can be found on the OECD’s PISA website.
What is the PISA Field Trial?
The PISA study is carried out in 2 stages, a field trial and a main study, with different schools selected for each stage. The field trial (March 2024) includes a smaller sample of schools and pupils than the main study (October 2025). The field trial ensures that PISA 2025 assessments, questionnaires and processes work as well as possible prior to the main study - it is therefore a very important and influential part of the study and your contribution is highly valued.
What does PISA involve?
The PISA assessment requires you to complete:
- An interactive onscreen assessment covering science, reading and mathematics
- A background questionnaire asking you about your life, school and learning experiences
What are the benefits of PISA?
Participating in PISA offers a range of benefits both for pupils, and more broadly for education in the UK.
