NCES Students' Classroom: Explore Your Knowledge
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. First take a quiz of 5-20 questions, then check each answer to see if you got it right. 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.
