This interactive map shows reading mean scores worldwide for countries participating in the Programme for International Student Assessment (PISA). PISA evaluates 15-year-old school pupils scholastic performance every three years in over 60 countries. Math and Science scores are also selectable from the list above the map.

PISA is coordinated by the OECD but non-OECD countries also participate. For comparison, see also the TIMMS scores world map, which is another international evaluation of pupils in Math and Science. See also: index of all interactive maps in StatWorld
