National percentile rankings for urban districts based on average scores for eighth-grade public school students in NAEP mathematics, by lower-income status and selected race/ethnicity categories: 2007
1 Sample size was insufficient to permit a reliable estimate for White and Hispanic students in Atlanta at grade 8, and White students in the District of Columbia at grade 8.
NOTE: Groups not shown are included in overall. In NAEP, students from lower-income families are those identified as eligible for the National School Lunch Program. Black includes African American, and Hispanic includes Latino. Race categories exclude Hispanic origin. The 50th percentile represents the middle score in the distribution of scores for public school students nationally. The average score for these students, however, fell below that point at the 47th percentile at grade 4 and the 49th percentile at grade 8 because there was a greater concentration of scores toward the lower end of the scale compared to the higher end.
