A teaching assistant is normally assigned to a freshman or sophomore calculus course taught by a faculty member and is responsible for one recitation section of approximately 22 students. Teaching assistants meet with their section one hour per week for a problem-solving session. They also have office hours (at most three hours per week) and grade exams and their students' homework. In return, the teaching assistantship provides a full tuition waver, as well as a stipend to cover living expenses.
Although there are no classes during the summer, graduate students normally remain in residence (except for vacation) to study and do research. Summer stipends to support this are generally available.
