NOTE: NAEP achievement levels define what students should know and be able to do. Basic denotes partial mastery of knowledge and skills that are fundamental for proficient work at a given grade. Proficient represents solid academic performance. Students reaching this level have demonstrated competency over challenging subject matter. Advanced signifies superior performance. NAEP reports data on student race/ethnicity based on information obtained from school rosters. Detail may not sum to totals because of rounding. Race categories exclude persons of Hispanic ethnicity.
