The Programme for International Student Assessment

The Programme for International Student Assessment (PISA) is the world’s biggest and most important international education study looking at the knowledge and skills of 15 year olds in Mathematics, Reading and Science.

Schools and pupils representing more than 70 countries participate in the study which provides high quality, internationally comparative data for education researchers, policy makers and schools worldwide.

Run by the OECD (Organisation for Economic Co-operation and Development) PISA was first conducted in 2000. The survey is repeated every three years and provides information to develop effective practice and a curriculum which both inspires pupils and matches the needs of the economic world.
