The extent and content of students' knowledge, as well as their ability to think, learn, and communicate, affect their likelihood of becoming productive adults and active citizens. Mathematics and reading achievement test scores are important measures of students' skills in these subject areas, as well as good indicators of overall achievement in school. To assess progress in mathematics and reading, the National Assessment of Educational Progress (NAEP) measures national trends in the academic performance of students in grades 4, 8, and 12.
Indicator ED2.A: Average mathematics scale scores for students in grades 4, 8, and 12, selected years 1990–2007

NOTE: Data are available for 1990, 1992, 1996, 2000, 2003, 2005, and 2007, although the 2003 and 2007 assessments only included grades 4 and 8. The 2005 assessment included a 12th-grade component, but the National Assessment Governing Board introduced changes in the 2005 NAEP mathematics framework for grade 12 in both the assessment content and administration procedures. As a result, the 12th-grade assessment results cannot be compared with those of previous assessments. In early years of the assessment, testing accommodations (e.g., extended time, small group testing) for children with disabilities and limited-English-proficient students were not permitted. In 1996, scores are shown for both the assessments with and without accommodations to show comparability across the assessments.

Indicator ED2.B: Average reading scale scores for students in grades 4, 8, and 12, selected years 1992–2007

NOTE: Data are available for 1992, 1994, 1998, 2000, 2002, 2003, 2005, and 2007, although the 2000 assessment only included grade 4, and the 2003 and 2007 assessments only included grades 4 and 8. In early years of the assessment, testing accommodations (e.g., extended time, small group testing) for children with disabilities and limited-English-proficient students were not permitted. In 1998, scores are shown for both the assessments with and without accommodations to show comparability across the assessments.

104 Among other changes, the framework was revised by merging the measurement and geometry content areas into one and by adding additional questions on algebra, data analysis, and probability.

105 The achievement levels define what students should know and be able to do at each grade. They are set by the National Assessment Governing Board (NAGB) and have undergone several evaluations but remain developmental in nature and continue to be used on a trial basis. Until the Commissioner of the National Center for Education Statistics determines that the levels are reasonable, valid, and informative to the public, they should be interpreted and used with caution.
