NOTE: The test for significance between the United States and the Organization for Economic Cooperation and Development (OECD) average was adjusted to account for the contribution of the U.S. average to the OECD average. Because PISA is principally an OECD study, the results for non-OECD countries are displayed separately from those for the OECD countries and are not included in the OECD average. Due to low response rates, data for the United Kingdom are not included. Participants were scored on a 1,000-point scale. The international standard deviation is 100 points.
