Using Medical College Admission Test-grade point average (MCAT-GPA) scores as a threshold has the potential to address issues raised in recent Supreme Court cases, but it introduces complicated methodological issues for medical school admissions.
To assess various statistical indexes to determine optimally discriminating thresholds for MCAT-GPA scores.
Entering classes from 1992 through 1998 (N = 752) are used to develop guidelines for cut scores that optimize discrimination between students who pass and do not pass the United States Medical Licensing Examination (USMLE) Step 1 on the first attempt.
Risk differences, odds ratios, sensitivity, and specificity discriminated best for setting thresholds. Compensatory versus noncompensatory procedures both accounted for 54% of Step 1 failures, but demanded different performance requirements (noncompensatory MCAT-biological sciences = 8, physical sciences = 7, verbal reasoning = 7--sum of scores = 22; compensatory MCAT total = 24).
Rational and defensible intellectual achievement thresholds that are likely to comply with recent Supreme Court decisions can be set from MCAT scores and GPAs.
将医学院入学考试平均绩点（MCAT - GPA）分数作为一个门槛，有可能解决近期最高法院案件中提出的问题，但这给医学院招生带来了复杂的方法学问题。
评估各种统计指标，以确定MCAT - GPA分数的最佳区分阈值。
使用1992年至1998年入学班级的学生（N = 752）来制定关于及格分数的指南，以优化区分首次参加美国医师执照考试（USMLE）第一步且通过与未通过的学生。
风险差异、比值比、敏感性和特异性在设定阈值时区分效果最佳。补偿性与非补偿性程序导致的USMLE第一步考试失败率均为54%，但对成绩要求不同（非补偿性：MCAT生物科学 = 8分，物理科学 = 7分，语言推理 = 7分——分数总和 = 22分；补偿性：MCAT总分 = 24分）。
可以根据MCAT分数和GPA设定合理且有依据的学术成就阈值，这些阈值可能符合最高法院近期的裁决。
