Analysed data from ten consecutive physiology examinations for medical students at Aarhus University are presented. Each examination comprised one MCQ test and one short-answer test. For both written aids were allowed; both were dominated by items above the recall level. The mean test scores of both the MCQ and the short answer tests were slightly above their mean pass levels with coefficients of variation around seven. Large but similar pass rate fluctuations in both test were found, and about half of the non-passing students failed both tests. The MCQ minimum pass level, established by the Nedelsky principle, was more stable than the essay pass level. The Nedelsky values seem to compensate for a large part of the fluctuations in the difficulty level of various MCQ sets. Due to lack of comparable data it cannot be settled whether the pass rate fluctuations are excessive, nor whether standards fluctuate more than those at other institutes.
本文呈现了对奥胡斯大学医学院学生连续十次生理学考试的数据分析结果。每次考试包括一场多项选择题测试和一场简答题测试。两场考试均允许使用书面辅助工具；两者都以高于记忆水平的题目为主。多项选择题测试和简答题测试的平均成绩略高于各自的平均及格水平，变异系数约为7。发现两场考试的及格率波动都很大，但波动情况相似，约一半未通过的学生两场考试都未通过。通过内德尔斯基原则确定的多项选择题最低及格水平比论述题及格水平更稳定。内德尔斯基值似乎在很大程度上补偿了各种多项选择题集难度水平的波动。由于缺乏可比数据，无法确定及格率波动是否过大，也无法确定标准波动是否比其他机构更大。
