This paper presents the three year process used in developing a teacher evaluation model for the Fort Worth (Texas) Independent School District. Based on Dr. Richard Manatt's School Improvement Model for Teacher Performance Evaluation, the purposes of the model were to improve teaching skills and to enable valid and reliable judgements concerning promotion, retention and termination of professional employees. The process involved (1) the selection and training of the nine teachers and nine administrators for the Teacher Evaluation Committee; (2) inservice training for evaluation of teachers through nine workshops; (3) establishing behavior criteria and standards in four performance areas (instructional skills, organizational and classroom management skills, professional performance, and interpersonal skills) and developing formative and summative evaluation instruments; (4) inservice administrator training on using the new instruments; (5) pilot testing the evaluation process with volunteer teachers; (6) analyzing the questionnaire and interview data from the pilot test; (7) field testing the revised evaluation process; and (8) making revisions for compliance with State of Texas House Bill 72 in regard to assigning teachers to career ladder levels based on observable, job-related behavior. Copies of the formative and summative evaluation report forms are appended. (BS)
