TAs are voluntary positions that require several hours of work each week (between 3-10 hours depending on the size of the class and the number of tasks). TA experience can be an extremely important experience to place on your academic resume and it can be personally rewarding. Usually, professors select students who have performed exceptionally well in one of their courses. However, if you are interested in working as a TA for a particular professor, have a strong academic record and a history of excellent time management skills, you are encouraged to share your interest with that professor. Before accepting this position, you should ensure that your schedule allows you to maintain a high level of commitment.
