Courses receive one CA or TF for every thirty students enrolled, although in most cases the more quantitative courses receive one for every twenty students enrolled.
Ratios are for the total combined CAs and TFs.
Generally a course receives only one TF per section unless it is a Ph.D. level course or a course requiring substantial writing from the students. Initial assignments are based on the previous year s enrollment. The primary difference between Course Assistants and Teaching Fellows is the level of their responsibilities and teaching. They generally are responsible for a full 1.5 hours of formal teaching per week in a scheduled review session. TFs may also be required to do more substantive assessment of student s written work in non quantitative courses with a heavy written component.
