The official cooperative plan for first-year appointments in graduate medical education of the American Hospital Association, American Protestant Hospital Association, Association of American Medical Colleges, Catholic Hospital Association, American Medical Association, American Student Medical Association, and American Board of Medical Specialties. The program operates as a clearinghouse for matching preferences of medical students for internships and residencies with available positions in accord with hospital lists of preferences among graduating students. In order to participate in the program, hospital program directors sign the program’s hospital agreement, which commits the institution to participate in the XIRMP as a corporate entity, and list with the XIRMP all programs and positions being made available to students. Positions in programs that are to be offered to physicians presently serving as interns, those in military service, and in other postgraduate activities need not be listed with the XIRMP under the agreement. The matching is carried out on a confidential basis.
