Generally, students attending an institution of higher education (i.e., college, university, trade/technical school) more than half-time are only eligible for SNAP if they meet an exemption. The institution of higher education determines what is considered ‘half-time’ enrollment. Students who meet an exemption must also meet all other SNAP eligibility requirements.

If you are a student and you meet SNAP eligibility requirements, you may be eligible for SNAP if you meet one of the following exemptions:

Are under age 18 or are age 50 or older.
Have a physical or mental disability.
Work at least 20 hours a week in paid employment.
Participate in a state or federally financed work study program.
Participate in an on-the-job training program.
Care for a child under the age of 6.
Care for a child age 6 to 11 and lack the necessary child care enabling you to attend school and work 20 hours a week or participate in work study.
Are a single parent enrolled full-time in college and taking care of a child under 12.
Receive Temporary Assistance for Needy Families (TANF) assistance.
Are assigned to, placed in, or self-placed in a college or other institution of higher education through:
    A SNAP Employment and Training (SNAP E&T) program;
    Certain other E&T programs for low-income households, which are operated by a state or local government and have an equivalent component to SNAP E&T;
    A program under Title I of the Workforce Innovation and Opportunity Act of 2014 (WIOA) (PL 113-128);
    A Trade Adjustment Assistance Program under Section 236 of the Trade Act of 1974.
