All TF appointments are made with the approval of the TF/TA, their advisor, and the course head for the class. In order to prevent interruptions or delays in payment, it is important that teaching appointments are processed as early as possible. Graduate students interested in a particular course should talk to the course head a few months in advance. At least two months before the course begins, all TFs and TAs should submit the TF/TA Application Form.

Keep in mind that you are required to teach during at least two semesters while in EPS. Talk with your advisor early on to determine when would be the best time for you to teach so that you will be able to keep up with your research. When you are ready to teach, you need to have approval from your advisor in addition to the course head for the class you'll be teaching. 

All teaching assignments are dependent on final course enrollment, which is determined at the Course Registration Deadline, about one week after the first day of classes. After the registration deadline, TF/TA positions may be eliminated if enrollment is lower than expected or added if enrollment is higher than expected. TFs/TAs whose positions are eliminated after the semester begins may be compensated for time worked.
