This report presents the national and state results of the NAEP assessment in mathematics and compares them to results from assessments in 2003 and in the first year data were available, usually 1990. In 2005, nationally representative samples of about 172,000 fourth-grade and 162,000 eighth-grade students nationwide participated in that assessment.
Fourth-graders' average score was 3 points higher, and eighth-graders' average score was 1 point higher in 2005 than in 2003 on a 0 to 500 point scale. The average scores increased since the first assessment year, 1990, by 25 points at grade 4 and by 16 points at grade 8.
Between 1990 and 2005, the percentage of fourth-graders performing at or above Basic increased by 30 percentage points, from 50 to 80 percent, and the percentage performing at or above Proficient increased from 13 to 36 percent. The percentage of eighth-graders performing at or above Basic was 17 percentage points higher in 2005 (69 percent) than in 1990 (52 percent), and the percentage performing at or above Proficient increased from 15 to 30 percent.

NAEP reports data on student race/ethnicity based on information obtained from school rosters. Figures 2 and 3 show results for five mutually exclusive categories: White, Black, Hispanic, Asian/Pacific Islander, and American Indian/Alaska Native. Black includes African American, Hispanic includes Latino, and Pacific Islander includes Native Hawaiian. Race categories exclude Hispanic origin unless specified.
At grade 4, the average scores for all three racial/ethnic groups were higher in 2005 than in any previous assessment year. White fourth-graders scored higher on average in mathematics than their Black and Hispanic peers in 2005. Higher percentages of White, Black, Hispanic, and Asian/ Pacific Islander students scored at or above Basic in 2005 than in any previous assessment year.
The average scores for White, Black, and Hispanic eighth-graders were higher in 2005 than in any previous assessment year. Higher percentages of Black and Hispanic students scored at or above Basic than in any previous assessment year at grade 8.
