At schools measuring progress in credit hours and semesters, trimesters or quarters, “half-time” is at least six semester hours or quarter hours per term for an undergraduate program. At schools measuring progress by credit hours but not using semesters, trimesters or quarters, “half-time” is at least 12 semester hours or 18 quarter hours per year. At schools measuring progress by clock hours, “half-time” is at least 12 hours per week. Note that schools may choose to set higher minimums than these. You must be attending school at least half-time to be eligible for a Stafford Loan. Half-time enrollment is not a requirement to receive aid from the Federal Pell Grant, Federal Supplemental Educational Opportunity Grant, Federal Work-Study and Federal Perkins Loan programs.
