Some North American universities have a special student position called preceptor. Preceptors are student volunteers who assist the staff professor and teaching assistants of a large lecture class by helping design certain lessons and holding his or her own office hours and review sessions. In some cases, volunteers are required to take an outside class focused on leadership development, where the final grade is determined by both the lecture professor and leadership development teacher. Thus, the preceptor earns credit for his or her preceptorship. It is considered a good leadership experience and reflects well on the student in his or her transcript. Preceptor can also refer to a paid student grader.
