U.S. history scores at all five selected percentiles for students who were eligible for free school lunch through the National School Lunch Program were higher in 2010 than in 2006. Scores at the 75th and 90th percentiles were higher in 2010 than in 2006 for students eligible for reduced-price lunch.
Because of the improved quality of the data on students' eligibility for NSLP, the percentage of students for whom information was not available has decreased compared to the percentages reported prior to the 2006 assessment. See the "demographics" tab to view the proportion of students in each category.
