本研究旨在建構教師專業發展評鑑之進階評鑑人員的能力構面，並分析進階評鑑人員對能力重要性與符合度的知覺差異。研究主要採問卷調查法，研究對象為全國之國民中小學進階評鑑人員，共得有效問卷514份，有效問卷回收率72%。研究結果發現：一、教師專業發展評鑑進階評鑑人員須具備的能力，包括評鑑制度理解、教學專業知能、資料蒐集與分析知能、評鑑倫理與人際互動知能；二、進階評鑑人員認同各構面能力的重要性，然能力符合度則為普通到非常符合之間，二者存有落差，其中又以資料蒐集與分析知能的落差最大；三、部分背景變項之進階評鑑人員所知覺能力的重要性、符合度或落差有所差異，包括年資、學校區域、階段、參加教學輔導教師認證及參加教師專業發展評鑑年數。最後，針對研究結果提出相關建議。

The purpose of this study is to establish the competencies of advanced evaluators of teacher evaluation for professional development, as well as to investigate the gap between their current and required competencies. Using a survey method, this study researched the advanced evaluators in elementary and junior high schools in Taiwan and obtained 514 questionnaires. The response rate of valid questionnaires is 72%. Main findings are as follows. 1. The competencies for advanced evaluators of teacher evaluation for professional development were an understanding of the teacher evaluation system, teaching expertise, data collection and analysis skills, and evaluation ethics and interpersonal competencies. 2. Advanced evaluators acknowledged the value of the four dimensions of evaluator competencies. They rated the level of their current competencies between average and good. There was a gap between the perceived level of importance and the current level of their competencies. The widest gap existed in their data collection and analysis skills, indicating their need for professional growth. 3. There were significant differences in the perceptions of the competencies’ level of importance, current state, and the gap between the current and required competencies, particularly regarding their teaching experiences, school locations, school levels, years of participating in the teacher evaluation, and whether the evaluators were involved in mentor training. Some recommendations are offered based on these findings.
