The development of a rationale and of a tentative set of guidelines for evaluating community junior college instruction is the focus of this report. Initially discussed is the range of purposes for which instructor evaluation might be undertaken, including promotion, tenure, and improvement of instruction. The choice of evaluators is then discussed, and students, academic administrators, and colleagues are considered. Next, student and instructor performance are investigated as criteria for evaluation. Finally, methods and techniques of evaluation are covered, with emphasis on the potential of electronic recording systems. Concluding the report are appendices outlining evaluation procedures, purposes, and guidelines; sample instructor evaluation criteria; and tables of current evaluation factors in use and their frequency of employment.
