3.4. Offers to Current TAs
Students who currently have a TA have a good, but not guaranteed, chance of getting an offer for the next semester. This decision is based on a number of criteria (see the criteria section below); this section discusses a few additional considerations.
It is department policy that students are eligible for a total of six semesters of TA support. This does not include any summer TA support, and is irrespective of the percentage of appointment; moreover, the department can provide exemptions to this rule based on departmental need. Note that the need is "departmental" (and so could cover, for example, rehiring an especially strong TA or a TA for a hard-to-fill TA position), but it is not the need of the student nor of their faculty advisor.
Having TAed less than three aggregate years does not guarantee a student continuing support, as a number of criteria are considered when TAs are appointed or reappointed. Long-term TAs should be particularly careful that they are making good degree progress, they can TA a number of different courses, and that their TA work is of exceptional quality.
Students who come in with TA support as part of the admission process are guaranteed an assistantship for one or two years. However, students with a one-year guarantee are almost always given a second year of support; and students are often given a third year of TA support if needed. Such students should make good degree process, do well in their TA work, and be able and willing to take on more advanced TA assignments (e.g., for advanced classes) in their second or third year. Note that second or third year support is not guaranteed in cases of seriously poor degree progress or TA performance.
