Make your expectations clear at the beginning of the semester.
Faculty agree that getting off to a good start is critical.
Maintain close contact with TAs throughout the semester. Facilitate the flow of feedback. Several faculty noted the importance of providing a forum that encourages TAs to keep you informed of what students already know and what they are having difficulty understanding. Similarly, they recommend providing TAs with regular feedback on the work they are doing. TAs balance their work for you with their research responsibilities.
