The Teaching Assistant Training and Teaching Opportunity (TATTO) program began in spring 1991 at Emory University to prepare graduate students to be teaching assistants, instructors, and tomorrow's professors, and is based on the premise that doctoral students should be trained in both teaching and research. The first part of the four-stage program is a three and one-half day course offered prior to the fall term and preceding a student's first teaching experience. Program faculty are among the best teachers from across the university, and the syllabus covers general topics important to students across disciplines. In the second stage of the program, students proceed to discipline-specific training in the department, with this optimally occurring at the same time as they participate in their first teaching opportunity--the teaching assistantship. The third stage is a closely monitored initial teaching opportunity supervised by a faculty member. The teaching associateship, the fourth stage, advances the graduate student to a teaching opportunity with greater responsibilities and allows the graduate student to co-teach with a faculty member. Evaluation of the program included student evaluations of the course, students' teaching portfolios, interviews with faculty members supervising the TATTO program, and interviews with representatives from 15 of the 20 departments within the College of Arts and Sciences.
