Increasing evidence indicates that some college students are experiencing food insecurity, which can negatively impact their academic success. However, college students are only eligible for Supplemental Nutrition Assistance Program (SNAP) in certain cases. Given the substantial federal investment in higher education and the risk posed if students do not complete their degrees, the Government Accountability Office (GAO) was asked to review food insecurity among college students. This report examines (1) what is known about the extent of food insecurity among college students and their use of SNAP; (2) how selected colleges are addressing student food insecurity; and (3) the extent to which federal programs assist students experiencing food insecurity. GAO reviewed relevant federal laws and agency documents and studies on student food insecurity; analyzed 2016 federal student data (the most recent available), and visited four states, selected based on actions taken to address student food insecurity, geographic diversity, and other factors. GAO recommends that the Food and Nutrition Service (FNS) (1) improve student eligibility information on its website and (2) share information on state SNAP agencies' approaches to help eligible students. FNS partially concurred, and plans to review its information. GAO continues to believe additional action is warranted, as discussed in the report.
