Title: A Poor Proxy for Poverty: Administrative Free and Reduced-Price Lunch Data and Household Income
Authors: Thurston Domina, Quentin Brummet, Nikolas Pharris-Ciurej, Andrew Penner, Sonya R. Porter, Emily Penner
Educational researchers often use National School Lunch Program (NSLP) data as a proxy for student poverty. Under NSLP policy, students whose household income is less than 130 percent of the poverty line qualify for free lunch and students whose household income is between 130 percent and 185 percent of the poverty line qualify for reduced-price lunch. Linking school administrative records for all 8th graders in one California public school district and in Oregon public schools to household-level IRS income tax data, we examine how well NSLP data capture student disadvantage. We find both that there is substantial disadvantage in household income not captured by NSLP category data, and that NSLP categories capture disadvantage on test scores above and beyond household income.
