1 Total includes other race/ethnicity categories not separately shown.
NOTE: Achievement levels are performance standards showing 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. (Below Basic, therefore, denotes less than this level of achievement.) 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. Race categories exclude persons of Hispanic ethnicity. The NAEP assessment was not administered to grade 12 in 2007. Detail may not sum to totals because of rounding.
