T he healthcare system in the United States is evolving quickly, with ongoing impacts on the field of physical medicine and rehabilitation (PM&R). In order for the specialty to remain relevant and to thrive in the future, residency programs must also evolve to produce PM&R physicians able to provide competent care within new systems and environments. An important opportunity to ensure that PM&R training provided in graduate medical education (GME) is both relevant and forward thinking to meet the needs of all relevant stakeholders and is through the revision process of residency program requirements at the Accreditation Council for Graduate Medical Education (ACGME). This opportunity was targeted for strategic planning by the leadership of the three major physiatry organizations: the American Academy of PM&R, Association of Academic Physiatrists (AAP), and the American Board of PM&R, recognizing that collaboration with shared resources would achieve the broadest input into identifying potential residency training requirement revisions that will best prepare physiatrists for future practice. The timeline and scope of this collaboration, and the details of the final recommendations provided to ACGME, will be described in this paper. Additional details are included for select recommendations that required deeper discussion and debate.The collaboration between the sponsoring organizations for this project extended over 8 yrs (Fig. 1). After strategic discussions in 2015, the leadership of the three participating PM&R organizations convened a GME summit in Chicago in July 2017, which was attended by over 50 physician organizational From the
