Summary[edit]

Description
English:  :Average test score in mathematics and science
Shown are Hanushek and Woessmann's combination of scores from international student achievement tests. The scores are standardized to the PISA test scale, so that the OECD countries have a mean of 500 and a standard deviation of 100. The test scores are not given for a particular year, but instead are the average of all standardized math and science test scores each country participated in.
