The estimates are based on Hanushek and Woessmann's combination of scores from international student achievement tests. Top students are those that reach a
level equivalent to 600 test-score points on the PISA scale (above one standard deviation of the average student in an OECD country). The estimates are not given for
a particular year, but instead are based on all standardized math and science test scores each country participated in.
