†Not applicable.
1 Scale ranges from 0 to 500.
2 Accommodations were not permitted for this assessment.
3 The 1996 data in this table do not include students who were tested with accommodations. Data for students tested with accommodations are not available at the state level for 1996.
4 Basic denotes partial mastery of the knowledge and skills that are fundamental for proficient work at the 8th-grade level.
5 Proficient represents solid academic performance for 8th-graders. Students reaching this level have demonstrated competency over challenging subject matter.
6 Advanced signifies superior performance.
7 Did not meet one or more of the guidelines for school participation in 2000. Data are subject to appreciable nonresponse bias.
8 Prior to 2005, NAEP divided the Department of Defense (DoD) schools into two jurisdictions, domestic and overseas. In 2005, NAEP began combining the DoD domestic and overseas schools into a single jurisdiction. Data shown in this table for years prior to 2005 were recalculated for comparability.
NOTE: For 2000 and later years, includes public school students who were tested with accommodations; excludes only those students with disabilities (SD) and English language learners (ELL) who were unable to be tested even with accommodations. SD and ELL populations, accommodation rates, and exclusion rates vary from state to state. Detail may not sum to totals because of rounding. Standard errors appear in parentheses.
