Students in the highest-performing U.S. states rank well below their peers in the world's top-achieving countries in mathematics and science skill, according to a new study that compares the performance of 8th graders. The analysis found that, on the one hand, most American states are performing as well as, or better than, most foreign nations in the study in math and science. But it also concludes that even students in high-performing states do not match students in top-performing foreign countries.
