With this study, all 52 states/jurisdictions that participate in the 2011 NAEP math and science assessments can compare the performance of their eighth-grade students with those of other countries. Overall, 36 states bested peers abroad in math, while 47 states topped peers abroad in science. Alaska students on average scored better than those of many nations. >
