Teaching Assistantships are positions appointed to graduate students in which they will aid with teaching tasks required in a course as outlined by the primary instructor. This may include marking of assignments and examinations, conducting demonstrations and supervising students (if a laboratory component is part of the course), as well as serving as the secondary instructor to some lectures if necessary. Teaching Assistants (TAs) are also expected to promptly respond to students' emails and to retain professionalism at all times in a classroom setting.
