The Supplemental Nutrition Assistance Program (SNAP) is the nation's most important anti-hunger program, providing food assistance to people with low incomes, including postsecondary students, workers, children, people with disabilities, seniors, and many more. The needs of college students have changed drastically over time, requiring more comprehensive supportive services that improve their ability to persist in and complete their education. Estimates of food insecurity among college students range widely, from 9 percent to over 50 percent, depending on the methodology and population studied. Food insecurity is associated with a range of negative health consequences that interfere with students' ability to attend and complete college. SNAP offers a modest assurance that people are able to meet their most basic human need for food. A GAO study found that approximately 1.5 million college students nationwide receive SNAP, but this is only a small share of those who could benefit from it. So few college students benefit from SNAP because of both eligibility restrictions and the fact that less than 4 out of 10 students who appear to be eligible for SNAP are receiving it. This brief explains the special eligibility rules for college students, describes what states and schools can do to expand access to SNAP, and answers other common questions about SNAP and students.
