This is the fourth report of the Commission on Public School Personnel Policies in Ohio to educators and the general public. The report is based on a survey of school superintendents, principals, teachers, and personnel directors in over 50 districts throughout the state. The report focuses on the need for teacher evaluation and the actions required to meet these needs. The report reviews various techniques for evaluation, basic training considerations for evaluators, aspects of improving skills of present evaluators, and general points for organizing evaluations. Some of the recommendations made by the Commission are a) school administrators should demonstrate competencies in the application of principles of sociology and psychology; b) course offerings should be reevaluated, establishing a priority for the development of skills used in teacher evaluation; c) pilot programs for improving skills of present evaluators should be established by school districts in conjunction with the Ohio State Department of Education; and d) ways for improving evaluation should be investigated by redefining the role of principal, organizing schools along plans of flexible staffing, and expanding the role of the department chairman to include evaluation. The appendix presents a description of the following forms of teacher evaluation: microteaching, interaction analysis, nonverbal teacher behavior category system, the Student Opinion Questionnaire, Style of Teaching Inventory, and About My Teacher questionnaire.
