The guidelines used by the Bowling Green State University, Ohio, speech communication department to assess graduate assistants' teaching skills are outlined in this paper. Visitations by observers, in conjunction with introductory sessions, weekly staff meetings, and teacher's manuals, can provide follow-up feedback regarding the implementation of activities and ideas, can stimulate the evaluation of teaching skills, can establish standards for improvement, and can let graduate assistants know that effective teaching is important. Criteria for evaluation are grouped in ten categories: preparation, structure, rapport, motivation, interaction, adaptation, poise, facilitation, physical environment, and overall pace of class. A sample visitation response form suggests specific standards for assessing skill levels in these areas and provides a concise method of feedback for the instructor. (KS)
