You can expect that the department will provide ongoing financial support for up to six years, including stipend, tuition remission, and insurance. This continued support may include a mix over time of GSR, Teaching assistantships, Teaching fellowships, competitive university fellowships, and competitive external fellowships. Historically, we have been able to provide such support to all students who are in good standing during their training. Please see the enclosed sheet for more information about our financial package.
