| | NAEP - Long-Term Trend: What Mathematics Measures |
 | | NAEP has assessed the mathematics achievement of 9-, 13-, and 17-year-olds ten times: in the school years ending in 1973, 1978, 1982, 1986, 1990, 1992, 1994, 1996, 1999, and 2004. |
 | | The mathematics trend assessments contained questions designed to measure performance on sets of objectives developed by nationally representative panels of mathematics specialists, educators, and other interested parties. |
 | | The objectives for each assessment prior to 1990 were based on the framework used for the previous assessment, with some revisions that reflected changes in the content of mathematics education. |
