We have some programs for all graduate students and special activities for Teaching Assistants. Here is an excerpt from Auburn's Graduate Assistant Handbook: 

"Graduate Teaching Assistants (GTAs) are responsible for laboratories, recitation sections, and, in some cases, regular classes of courses numbered below 6000. GTAs are not permitted to teach courses numbered 6000 or above, though they may assist with laboratories for such courses. Additionally, they may not teach or assist with a course in which they are enrolled. Whatever their instructional responsibilities, GTAs should be supervised by a faculty member who is responsible for monitoring and evaluating their performance. GTAs who have no prior teaching experience should be given some form of training before being allowed to teach. Any GTA with primary responsibility for a course must have a minimum of eighteen semester hours of graduate course credit in that field of instruction."

Graduate students are also eligible to enroll in the Graduate Certificate in College/University Teaching as well as the Graduate Teaching Fellows program (coming Fall 2011).
