Pediatric residency milestone performance is not predicted by the United States Medical Licensing Examination Step 2 Clinical Knowledge.

OBJECTIVES

This study aims to show whether correlation exists between pediatric residency applicants' quantitative scores on the United States Medical Licensing Exam Step 2 Clinical Knowledge examination and their subsequent performance in residency training based on the Accreditation Council for Graduate Medical Education Milestones, which are competency-based assessments that aim to determine residents' ability to work unsupervised after postgraduate training. No previous literature has correlated Step 2 Clinical Knowledge scores with pediatric residency performance assessed by Milestones.

METHODS

In this retrospective cohort study, the United States Medical Licensing Exam Step 2 Clinical Knowledge Scores and Milestones data were collected from all 188 residents enrolled in a single categorical pediatric residency program from 2012 - 2017. Pearson correlation coefficients were calculated amongst available test and milestone data points to determine correlation between test scores and clinical performance.

RESULTS

Using Pearson correlation coefficients, no significant correlation was found between quantitative scores on the Step 2 Clinical Knowledge exam and average Milestones ratings (r = -0.1 for post-graduate year 1 residents and r = 0.25 for post-graduate year 3 residents).

CONCLUSIONS

These results demonstrate that Step 2 scores have no correlation to success in residency training as measured by progression along competency-based Milestones. This information should limit the importance residency programs place on quantitative Step 2 scores in their ranking of residency applicants. Future studies should include multiple residency programs across multiple specialties to help make these findings more generalizable.
