The National Resident Matching Program (NRMP) Main Residency Match occurs in mid-March each year. At that point, tens of thousands of students nearing completion of medical school and other physicians are matched with tens of thousands of graduate medical education (GME) training positions in nearly 6,000 training programs. With the merger of the Accreditation Commission for Graduate Medical Education (ACGME) and the American Osteopathic Association (AOA) accreditation system between 2015 and 2020, the “NRMP Main Match” now covers an estimated 96 percent of the physicians entering GME in the US. This post looks at some of the major takeaways from the 2021 NRMP Match including the implications for the physician workforce.
