A Brief History of USMLE Foundation
The United States Medical Licensing Examination (USMLE) was introduced in 1992 to create a unified and standardized licensing examination system for physicians across the United States. Before the USMLE, multiple examinations were used by different organizations and states, creating inconsistencies in physician assessment.
The National Board of Medical Examiners (NBME) and the Federation of State Medical Boards (FSMB) collaborated to establish a single pathway that would evaluate whether physicians possess the knowledge and skills required for safe medical practice.
Over the years, the examination evolved to place greater emphasis on clinical reasoning, evidence-based medicine, and patient-centered care. One of the most significant changes occurred in 2022 when Step 1 transitioned from a three-digit numerical score to a Pass/Fail reporting system. This change aimed to reduce excessive competition while encouraging a more holistic evaluation of residency applicants.
