The purpose of this study was to determine the interrater reliability of the Texas Teacher Appraisal System instrument. The performance indicators, criteria, domains, and total instrument were analyzed for inter rater reliability. Five videotaped teaching episodes were viewed and scored by 557 to 881 school administrators trained to utilize the Texas Teacher Appraisal System. The fifty-five performance indicators were analyzed for simple percentage of agreement. The ten criteria, four performance domains, and) the whole instrument were analyzed utilizing Ruder-Richardson Formula 20. Indicators were judged reliable if there was 75 percent or greater agreement on four of the five videotaped exercises. Criteria, domains, and the whole instrument were judged reliable if they yielded a -Ruder-Richardson Formula 20 score of .75 or greater on four of the Based on the findings of this study, the following conclusions v/ere drawn: 1. Forty-eight of the fifty-five performance indicators were reliable in evaluation teacher performance. 2. Seven of the performance indicators were unreliable in evaluating teacher performance. 3. None of the ten performance criteria appeared to be reliable in evaluating teacher performance. 4. None of the four performance domains appeared to be reliable in evaluating teacher performance. 5. The whole instrument was reliable in evaluating teacher performance. 6. Reliability problems with the criteria and domains appeared to be an underestimate of reliability of the Kuder-Richardson Formula 20.
