Candidates for the PhD must normally demonstrate satisfactory performance as a Teaching Assistant in undergraduate courses at Brown, or in teaching at another institution approved by the Department. Currently, doctoral students most commonly teach in years 2, 3, and 5. Students who receive standard funding for year 6 typically TA for one semester and are on fellowship in the second.
Students preparing for the examinations will normally be given preference in the assignments for teaching assistants and proctors. Work loads for such positions will conform to standards set by the Graduate School: "limited enough in scope [requiring no more than 20 hours per week] so that normal progress can be made in the student's educational program."
