1997年《教育統籌委員會第七號報告書》建議，以外在和內在的質素保證機制來保證香港學校的教育質素。本文探討香港學校教育質素保證架構的早期發展，並分析和比較內外質素保證機制的效能、優點和缺點。本文亦介紹學校自我評估的概念和基本步驟，及香港中文大學學校發展及評估組所推行一系列學校發展計劃的內容，好使學校行政人員掌握以自我評估來管理學校發展的技巧。在文章最後一節，筆者從三個議題評析「香港學校教育質素保證架構」的最新發展，並作出建議。

The Education Commission Report No. 7 recommended that Hong Kong schools should adopt a two-pronged approach, which includes an internal quality assurance mechanism and an external quality assurance mechanism, to assure the quality of school education. This article attempts to review the development of such an approach since 1997 and to compare the effectiveness of the two mechanisms as well as their strengths and weaknesses. The author then introduces the concept of school self-evaluation and its basic steps of implementation. There are also delineations of the school improvement projects organized by the School Development and Evaluation Team of The Chinese University of Hong Kong, including their aims, strategies and deliverables. In the final session, the author reviews the recent development of the School Development and Accountability Framework in Hong Kong, in which three areas of interest are reviewed and suggestions for further development are made.
