Full-time student status for most employer sponsored or family health insurance plans is normally considered 9 credit hours. Some health insurance carriers require enrollment in a minimum of 12 credits. Check with your employer or family health insurance company for their minimum enrollment requirement.
Full-time undergraduate student status for financial aid purposes and enrollment verification is 12 credit hours or more. Enrollment in 9 to 11 credits is classified as three-quarter time. Enrollment in 6 to 8 credit hours is classified as half-time. Less than half-time or part-time is 5 credit hours or less.
