What is the difference between half-time and full-time status?

Half-time and full-time Enrollment Status is determined on a trimester to trimester basis:

As an undergraduate student, you must complete 6 credit hours within the trimester to be considered half-time and 12 credit hours within the trimester to be considered full-time.

As a graduate student, you must complete 3 credit hours within the trimester to be considered half-time and 6 credit hours within the trimester to be considered full-time.
