This article is designed to serve as a guide for emergency medicine (EM) educators seeking to comply with the measurement and reporting requirements for Phase 3 of the Accreditation Council for Graduate Medical Education (ACGME) Outcome Project. A consensus workshop held during the 2006 Council of Emergency Medicine Residency Directors (CORD) "Best Practices" conference identified specific measures for five of the six EM competencies--interpersonal communication skills, patient care, practice-based learning, professionalism, and systems-based practice (medical knowledge was excluded). The suggested measures described herein should allow for ease in data collection and applicability to multiple core competencies as program directors incorporate core competency outcome measurement into their EM residency training programs.
