Racial and Ethnic Bias in Medical School Clinical Grading: A Review

Abstract

Objective: Improving diversity in healthcare is a widely recognized national goal. The diversity of medical student matriculants has increased, yet this trend is not seen in the composition of competitive residency programs. In this review, we examine racial and ethnic disparities in medical student grading during clinical years and explore the consequences of how this may exclude minority students from accessing competitive residency positions.

Design: Following PRISMA guidelines, we searched PubMed, Embase, Scopus, and ERIC databases using variations of the terms "race," "ethnicity," "clerkship," "rotation," "grade," "evaluation", or "shelf exam." Of 391 references found using the criteria, 29 were related to clinical grading and race/ethnicity and included in the review. The GRADE criteria were used to determine the quality of evidence.

Setting: Johns Hopkins School of Medicine, Baltimore MD.

Results: Five studies examining a total of 107,687 students from up to 113 different schools found racial minority students receive significantly fewer Honors grades in core clerkships compared to White students. Three studies examining 94,814 medical student evaluations from up to 130 different schools found significant disparities in the wording of written clerkship evaluations based on race and/or ethnicity.

Conclusions: A large body of evidence suggests the presence of racial bias in subjective clinical grading and written clerkship evaluations of medical students. Grading disparities can disadvantage minority students when applying to competitive residency programs and may contribute to a lack of diversity in these fields. As low minority representation has a negative impact on patient care and research advancement, strategies to resolve this issue must be further explored.
