背景：校本評核是教育改革的新方案，不少國家引入校本評核輔助公開考試，拓闊評核的基礎，提升學習效能，然而很多研究發現教師對評核變革的信念足以影響其實施。
目的：香港中學會考中國語文於2005-06學年實行校本評核，本研究以個案形式探討教師對校本評核的信念及其如何回應此變革。
研究對象：兩位高中中文教師
研究方法：採用半結構式訪談及檔分析蒐集資料
研究結果：研究發現乙老師支持校本評核，採取積極態度，安排各種評估活動，豐富學習與評核的內容；而甲老師卻持觀望態度，採取最省時省力的方法實施校本評核而不影響教與學的常態，反而致力幫助學生應付公開考試。
結論：研究揭示教師的信念影響其態度、決策與行動，為政策制定者帶來重要的啟示。
Background: School-based assessment is a new initiative of education reform. Many countries from different parts of the world have introduced SBA to supplement public examinations, broaden the assessment base and enhance learning effectiveness.

This paper aims to show that the implementation of school-based assessment (SBA) has proved to have positive impact on the performance of students in the public oral examination. An SBA component was introduced to the Hong Kong Certificate of Education Examination English Language Examination in 2007. This consists of a reading / viewing programme where students need to read / view texts, write up some comments and personal reflections, and then take part in a discussion with classmates on the texts they have read / viewed, or make an individual presentation and respond to questions. The assessment is based on the student’s oral performance. The 2007 experience has shown that the speaking ability of students can be reliably assessed in school by their own teachers. Statistically, the SBA component has proved to be as reliable as the speaking examination. The beneficial washback of SBA can be seen in the results of the speaking examination. Candidates from schools that submitted SBA marks had a lower absentee rate than candidates from schools not submitting SBA marks. They also performed better in the speaking examination.
本文旨在顯示推行校本評核證實對學生在公開考試的口試表現有正面影響。香港中學會考英國語文科在2007年引進校本評核，學生須閱讀或閱覽各種文本，包括小說類及非小說類的書籍及影片，並寫下評論及個人感想，然後與同學進行小組討論，或作個人短講並回答提問。旨在評核學生的說話能力。根據2007年的體驗，老師能可靠地評核學生的說話能力。統計資料亦顯示校本評核和口試的信度相若。校本評核的正面影響可見於公開口試的成績 ，於進行校本評核的學校就讀的考生缺席率較低，成績也較佳。
