State-level results in mathematics are available for eight assessment years (at grade 8 in 1990; and at both grades 4 and 8 in 1992, 1996, 2000, 2003, 2005, 2007, and 2009), although not all states may have participated or met the criteria for reporting in every year. All 50 states, the District of Columbia, and the Department of Defense Schools participated in the 2009 mathematics assessment at grades 4 and 8. For the first time in 2009, grade 12 mathematics results are also available for the 11 states that volunteered for the assessment and met the reporting criteria. Grade 12 results follow the grade 4 and 8 results in the NAEP reporting schedule.
The state snapshot reports and their companion, The Nation's Report Card: Mathematics 2009, provide a look at the main results of the NAEP 2009 mathematics assessment. Each participating jurisdiction receives its own customized state report, as seen here. The Nation's Report Card: Mathematics 2009 offers data for all participating states and additional national data. The NAEP Data Explorer provides information for all jurisdictions for which results are reported in 2009 and allows the user not only to develop custom data tables, but also to perform appropriate tests of statistical significance for within- or across-state data comparisons.
Within each state report, the overall scale score and achievement-level results are provided, in addition to student group results. The information is presented on a single page for each grade assessed in the particular state or jurisdiction.
