- This map shows countries by best-ranked academic subject.
- Data comes from the 2012 PISA test, which measures academic achievement worldwide in math, reading and science.
- Ties in ranking were broken by highest score.
- For some countries/regions that did not participate in 2012, their 2009 PISA score is used.
