Average math and reading scores for 4th-grade public school students

While the average scores nationwide on NAEP have been flat for a decade, statewide scores in California and in three urban districts that separately take the test have risen steadily in reading and fluctuated in math. NAEP scores are defined as basic, designating partial mastery of academic content, proficient, defined as solid mastery of content, and advanced. Proficiency on NAEP is harder to obtain than proficiency on most state tests.
