The Teaching Assistant Project (TAP) is a multi-tiered initiative designed to promote excellence in undergraduate and graduate education at Rutgers, New Brunswick, through the professional development of the graduate student teaching staff. TAP is, by necessity, a flexible endeavor, working to meet the changing needs of teaching assistants. The fundamental components upon which this project is built include the annual orientation, certificate programs and special issues seminars, web-based publications, and discipline-specific training.
