It assesses the knowledge and skills of 15-year-olds in science, reading, maths and collaborative problem solving and was developed jointly by member countries of the Organisation for Economic Co-operation and Development (OECD).
In 2015, PISA in Scotland was delivered by the National Foundation for Educational Research (NFER). The PISA survey has a three year cycle, focusing in turn on science, reading and maths.
The main focus in 2015 was science, with some questions assessing reading, maths and problem solving. For the first time, the PISA assessment was wholly computer based.
Findings from the survey will inform education policy in the UK and other countries, and will be used to improve teaching and learning in science, maths and reading for students around the world.
