Students may serve as teaching assistants for first-year and upper-level courses. (Teaching assistant positions in the moot court and lawyering process program are also available but they are handled differently and are not covered under this description.) Teaching Assistants must successfully have completed the course for which they are applying (though not necessarily with the same professor) and must receive written permission of the professor whom they would assist. Teaching assistants are required to attend classes and complete all reading assignments. In addition, teaching assistants will (1) undertake at least two meaningful teaching experiences (e.g., conducting review sessions, classroom exercises or other form of direct instruction), (2) devote at least 21 hours during the course of the semester to the holding of meetings with individual students taking the course, (3) at least twice during the semester take the lead in drafting educational materials, and (4) attend tutorial sessions with the professor who will provide feedback on the student's work. Teaching assistants are prohibited from involvement in formulating, drafting, or grading the final exam, or participating in any other way in the grading of students. Teaching assistants will receive one credit fewer than the students taking the course, to be graded on a pass/fail basis. These credits count against the student's maximum number of ungraded hours during law school, but will not be included in the total that may not exceed 8 credits for Special Research Projects or Externships that a student may take prior to graduation. Students must pay for these credits as they do any other; the law school cannot and does not waive or reimburse students for these charges (as it does for Lawyering Process and Moot Court TA'S).
