According to the Graduate School, the workload of a Teaching Assistant ordinarily requires between 350-370 hours per semester, but a 50 percent appointment should not normally exceed 20 hours per week. For a 33 percent appointment, the work should not normally exceed 240-254 hours per semester, or a little more than 13 hours per week. Still, Teaching Assistants are not paid hourly and their workload will be heavier some weeks than others, so not every week will require precisely 20 hours, and some may require considerably more. Time investments vary considerably depending on the kinds of activity required, familiarity with the material taught, and the teacher\u2019s experience. New Teaching Assistants frequently spend much more time preparing than experienced assistants.<\/p>\n\n\n\n
