The National Center for Education Statistics offers math, history, and geography quizzes for grades 4, 8 and 12, civics quizzes for grades 4, 8, and 9, science quizzes for grades 4 and 8, and economics quizzes for grade 12. Along with the quizzes are some very interesting results comparisons: click on "Results around the World," and see what percentage of students answered each question correctly, in the USA and in a dozen other countries. Click a country on the map and compare that country's results with the international average.
