The National Assessment of Educational Progress (NAEP) is the only test that assesses what U.S. students know and can do in various subjects across the country. These subjects include arts, civics, economics, geography, mathematics, reading, science, technology and engineering literacy, U.S. history, and writing. Teachers, principals, parents, policymakers, and researchers all use these results to assess progress and develop ways to improve education at all levels.

General information about NAEP is available at http://nces.ed.gov/nationsreportcard/.
