本研究使用北部某私立大學100至103學年入學學生之追蹤資料，驗證退學標準由嚴格變為寬鬆後，對學生學業學習之影響。本文發現寬鬆的退學標準將導致學生整體的科目不及格率與二分之一學分不及格機率顯著上升，且加權平均 Z分數顯著下降，其中以成績中後段學生的影響最為劇烈，而成績前段的學生雖然學期加權平均成績、科目不及格率、二分之一學分不及格機率未因退學標準放寬而有所影響，但他們的加權平均Z分數卻顯著衰退。本文認為學生學習態度行為改變，或許是造成學生在退學標準放寬後的成績表現退步的可能原因之一。

This study examines the impact of adopting a less strict academic dismissal policy on students’ academic performance. By utilizing academic performance panel data of students attending a private university located in Northern Taiwan from the 2011–2014 academic year, we find that the policy may increase the students’ failed-credit proportion and the likelihood of half the number of credits failing. In addition, this policy may decrease the weighted Z scores. These findings may be driven by the fact that students put less effort into their studies.
