# Pass/Fail Grading and United States Medical Licensing Examination (USMLE) Step 1 Reform: Implications for Clinical-Year Assessment and USMLE Step 2 Clinical Knowledge (CK) Performance

## TL;DR

This paper examines how pass/fail grading in medical education and USMLE Step 1 reform affect student well-being and performance in later exams.

## Contribution

The paper provides a synthesis of evidence on the impact of pass/fail reforms on medical student outcomes and assessment practices.

## Key findings

- Pass/fail grading in preclinical years improves well-being without harming USMLE Step 1 performance.
- Step 1 pass/fail reporting shifts evaluation focus to Step 2 CK and clinical assessments.
- Variability and equity concerns arise in workplace-based assessments post-reform.

## Abstract

The transition to pass/fail grading in undergraduate medical education (UME), alongside the change to pass/fail reporting for the United States Medical Licensing Examination (USMLE) Step 1, represents a substantial shift in assessment across the medical education continuum. These reforms were motivated by concerns regarding learner well-being, excessive competition, and misalignment between assessment practices and educational goals. This narrative review synthesizes empirical, survey-based, and conceptual literature to examine the effects of preclinical pass/fail grading and Step 1 pass/fail reporting on learner outcomes, clinical-year assessment, and USMLE Step 2 Clinical Knowledge (CK) performance. Across national and institutional studies, preclinical pass/fail grading is associated with improved learner well-being without evidence of inferior Step 1 or Step 2 CK performance. Early post-reform evidence suggests that Step 1 pass/fail reporting has redistributed evaluative emphasis toward Step 2 CK and clinical-year performance measures, raising concerns regarding variability and equity in workplace-based assessment. Collectively, the literature underscores the importance of transparent, equitable, and programmatic assessment systems during the clinical years.
