Transition From Normative to Criterion-Based Grading in the Obstetrics and Gynecology Clerkship.

Objectives: To compare grades, National Board of Medical Examiners (NBME) Shelf Exam scores, and student satisfaction with the Obstetrics and Gynecology (OB/GYN) clerkship after transitioning from normative to criterion-based grading.

Methods: Between July 2021 and July 2022, the Icahn School of Medicine at Mount Sinai (ISMMS) adhered to a normative grading scheme in which ∼60% of students achieved a grade of Honors, 30% achieved a grade of High Pass and 10% achieved a grade of Pass for the OB/GYN clerkship. In July 2022, ISMMS transitioned to a criterion-based scheme. In this scheme, 6 competencies were created. Criteria were determined for each competency, delineating achieving a score of "Pass" versus "Honors" for the specific objective. Students needed to meet the criteria for Honors for 4 out of 6 of the competencies in order to ultimately receive a grade of Honors for the clerkship. The number of students achieving Honors, NBME shelf exam scores, and student clerkship satisfaction ratings between the normative and criterion-based schemes were compared.

Results: The number of students studying in academic year (AY) 2021-2022 and AY 2022-2023 were 134 and 137, respectively. A significantly lower percentage of students received Honors in AY 2021-2022 than in AY 2022-2023 (66% vs. 96%,  < .01). Mean exam scores were significantly higher for those receiving Honors in AY 2021-2022 than in AY 2022-2023 ( < .05); scores for AY 2021-2022 and AY 2022-2023 were 78.9, 95% CI [77.6, 80.1] and 76.7, 95% CI [75.6, 77.8], respectively. Mean exam scores for all students were not significantly different between the 2 academic cohorts (77.8 vs. 76.2,  = .06). Clerkship satisfaction rating was significantly higher in AY 2022-2023 than in AY 2021-2022 (4.1 vs. 3.7,  < .05).

Conclusions: These findings support a paradigm that compares learner performance to predefined measures as opposed to peer performance.
