|Figure 24-1: Average mathematics scale scores of 4th- and 8th-grade students: Selected years, 1990-2011|
NOTE: At grades 4 and 8, the National Assessment of Educational Progress (NAEP) mathematics scale ranges from 0 to 500. Testing accommodations (e.g., extended time, small group testing) for children with disabilities and English language learners were not permitted in 1990 and 1992; students were tested with and without accommodations in 1996. For more information on NAEP, see Appendix B – Guide to Sources.
