Voluntary Program Rank Order List Lock Pilot

The National Resident Matching Program® (NRMP®) is pleased to announce the Voluntary Program Rank Order List (ROL) Lock Pilot initiative with the partnership of the Internal Medicine, Pediatrics, and Vascular Surgery specialties. Programs in those three specialties will have the opportunity to participate in the pilot again for the 2027 Main Residency Match. This pilot, which began with the 2026 Main Residency Match, will make it possible for the NRMP, and participating programs, to explore the merits and utility of voluntary functionality that would allow programs to “lock” their rank order lists in the NRMP’s Registration, Ranking, and Results® (R3®) system.
