NAEP is the largest nationally representative and continuing assessment of what America's students know and can do in various subject areas. Assessments are conducted periodically in mathematics, reading, science, writing, the arts, civics, economics, geography, and U.S. history. Often called the "Nation's Report Card," NAEP provides information about trends in State and national student achievement over time and allows educational achievement to be compared across States.  General information about NAEP is available at
