What is Pisa?
The Programme for International Student Assessment (Pisa) provides education rankings based on international tests taken by 15-year-olds in maths, reading and science.
The tests, run by the OECD and taken every three years, have become increasingly influential on politicians who see their countries and their policies being measured against these global school league tables.
Asian countries continue to dominate, with Singapore rated as best, replacing Shanghai, which is now part of a combined entry for China.
