Graduate course load is expressed in trimester credits. A trimester credit represents one 55-minute class or equivalent per week for 14 weeks. Laboratory courses are calculated at a 2:1 or 3:1 ratio, with two or three 55-minute periods of lab time each week making up one trimester credit. Clinical courses are measured according to the policies of the graduate program. For nurse anesthesia students, eight-hour periods of clinical time each week make up one trimester credit (8:1 ratio). For occupational therapy students, forty-hour periods of clinical time each week make up one trimester credit (40:1 ratio). Full-time graduate students are defined as those who register for eight or more credits per trimester. A graduate student may not be concurrently registered at another college or university and Adventist University of Health Sciences without permission from the department chair and Office of Academic Administration.
