隨著高教體系的發展，傳統大學生學期成績的給分及排名方法有欠公平，本研究旨在使用常態分配法調整大學生學期成績並據以排名，以改進此缺點。依據常態分配觀念所發展出的創新學期成績調整及排名法，可更公平地對待學生，進而協助積極努力的學生建立信心、獲得成就。本研究以假設的四門學科學期成績為例，說明此模式的應用，並對照彰顯傳統學期成績給分及排名的未盡完善之處，以見兩者之差異。

With the development of the higher education system, traditional methods of score assignment and grading for University students’ learning achievements are not always fair. The purpose of this study is to provide Z scores to adjust assigned scores and grades to improve fairness through normal distribution. This novel method helps students develop a positive attitude and builds their confidence. Numerical examples of 4 courses are used to illustrate the model’s effectiveness and to compare learning achievement scores and grades between the traditional methods and the novel method.
