Another shelf examination in the books. The usual story of some easy giveaways, some questions made so nebulous in an attempt to avoid buzzwords that the answer is equally nebulous, and a few questions that you have to tell yourself “surely this is an experimental question…”

The National Board of Medical Examiners (NBME) was established in 1915 to create standardized exams for assessing physician competency. Early NBME exams were comprehensive and used primarily for licensure, not for coursework or clerkship assessment. In the 1970s, the NBME introduced Subject Examinations — what we now call “shelf exams” — to test medical students’ knowledge in specific disciplines (e.g., Internal Medicine, Surgery, Pediatrics). These exams were designed to supplement medical school curricula and standardize evaluation across institutions, especially for third-year clerkships.

In the 1990s, the USMLE (United States Medical Licensing Examination) series was introduced to unify medical licensure exams in the U.S. While USMLE Step 1, 2 CK, and 3 became the core licensure pathway, NBME shelf exams remained separate but were increasingly adopted by medical schools as formative or summative assessments during clinical rotations.

Today, nearly all U.S. medical schools use shelf exams as part of the third-year core clerkship evaluations, despite not being formally part of the USMLE. Administered by the NBME, these standardized tests serve as a benchmark to compare students nationwide and predict performance on USMLE Step 2 CK (the most important examination in the current era for residency).

All of that to say… today was an important day and…
