UACCB uses the credit hour as a standard unit of credit for college-level courses. A credit hour is defined as an institutionally established equivalency that reasonably approximates some minimum amount of student work reflective of the amount of work expected in a Carnegie unit. One semester credit hour equals 15 hours of academic work. For example, during fall and spring semesters, one credit hour = 15 weeks x (1 classroom hour + 2 out-of-class work hours). Classes that meet three hours per week, for example, carry three hours of credit per semester. Laboratory and clinical hours are calculated using a different formula.
