The responsibility for preparing teaching assistants is largely dependent on the setting. While many faculty members at four-year institutions are responsible for preparing their teaching assistants, this task is handled on a department-wide or campus-wide basis in programs with large numbers of graduate students. Many professional societies have publications on this topic (see Appendix A). The American Association for Higher Education is another excellent source of information. Their publication Preparing Graduate Students to Teach (Lambert and Tice, 1993) provides numerous examples of teaching assistant training programs in a wide array of disciplines.
