Scores at the 25th, 50th, 75th percentiles for students who were eligible for the National School Lunch Program were higher in 2009 than in 2007.
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 2003 assessment. See the proportion of students in each category in the NAEP Data Explorer.
