Why should medical students take on the added stress of preparing for two board exams despite the unified match? Is taking USMLE Step 1 as a DO student still worth it when they already have the COMLEX Level 1? Yes!
Many DO students have continued to take USMLE Step 1 in addition to the COMLEX Level 1 to improve the competitiveness of their residency applications. Here’s why.
Most Program Directors Are More Familiar With the USMLE Grading Scale
Last year’s merger of the American Osteopathic Association (AOA) and the Accreditation Council for Graduate Medical Education (ACGME) resulted in a unified ACGME match for both MD and DO candidates.
Yet, though all medical programs are now open to both MD and DO applicants, there are many more allopathic (MD) students than osteopathic (DO) students. This means there are more students applying for residency using USMLE scores than COMLEX scores.
Likewise, there are more original ACGME programs than original AOA programs. As such, most program directors are more familiar with the USMLE grading scale than the COMLEX grading scale. This means they are more likely to feel comfortable accepting an equally qualified applicant who submits a USMLE score with a COMLEX score than an applicant who submits a COMLEX score alone.
No COMLEX Level 1 to USMLE Step 1 three-digit score conversion formula has been widely accepted. (Even though some attempts can be found online). In fact, many residency programs have been advised to use caution when utilizing any such formula to derive a USMLE Step 1 score from a COMLEX Level 1 score. As such, providing a valid USMLE Step 1 score remains a competitive advantage in the residency application process for test takers.
Still, as a study published by the ACGME in The Journal of Graduate Medical Education shows, there is a strong positive correlation between COMLEX Level 1 scores and USMLE Step 1 scores. The following graph provides an estimate as to where you might fall on Step 1 based on your Level 1 score or most recent COMSAE, based on exam percentiles.
