本文針對行之有年的國中基本學力測驗量尺分數的使用問題，探出學理與實務上的反省與評論。從學理上而言，現行量尺分的使用，有其學理上的優勢與強而有力的實徵證據支持；從實務上而言，卻有不易被大眾理解與釋懷質疑之處；但從政策上而言，它卻已經部分達成當初的教改使命。因，是否需要改變行量尺分數的使用，各有其考量的優劣點存在，很難斷然回答是或曾。不過，從本文的檢討與省思中可知，我們尚需要考量更多的研究報告、民意的觀點、與政據達成效益幾個層面，進一步審慎思考，才能做出一個完美的政策決策。 This paper had reflected and commented on the usage of scaled scores in the Basic Competency Test for the Junior High School. Theoretically speaking, the current usage of scaled scores had many advantages and got strongly supported by the empirical evidences. In practice, the usage of scaled scores caused many doubts and was not easily understood by common layers. But form the perspective of policy making and execution, the usage of scaled scores had partially fulfilled the goals of the Education Reform. So, was it necessary for changing of the usage of scaled scores? It was really hard to answer this question: yes or no. therefore, we needed more evidences of the empirical studies, sincerely thought about people’s opinions, and considered the effectiveness of the policy execution. Then, we could make the more perfect policies, again.
