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 interviewed researchers; officials from Education, FNS national and regional offices; and officials at 14 colleges, including students at 8 of these colleges. GAO also emailed all state SNAP agencies about their efforts related to students.
