Approximately 75% of U.S. emergency medicine residency programs follow a three-year training format. However, the landscape is shifting. In winter 2025, the Accreditation Council for Graduate Medical Education released a proposed recommendation that all emergency medicine residencies transition to a four-year format by 2027.
Yale Emergency Medicine has led the way, offering a four-year emergency medicine training program since its inception in 1996. “The merits of four years are clearer than ever,” says Arjun Venkatesh, MD, MBA, MHS, chair of Yale Emergency Medicine.
“Biomedical knowledge has exploded. The role of the emergency physician now spans pre-hospital care, observation medicine, urgent care, telemedicine, and complex team leadership. We long believed this expanded skill set demands more training, and now the rest of the country is catching up.”
Some institutions are going even further, offering five-year residency options. These programs provide extra training in research or leadership.
Yale pioneered this approach with the Yale Emergency Scholars (YES) Program. This unique five-year pathway combines a fully accredited residency with a complete research fellowship in an accelerated five-year format.
“Our goal is to train the next generation of emergency physician-scientists,” says Caitlin Ryus, MD, MPH, co-director of YES. “We provide individualized mentorship; help navigate the K-award process and build sustainable academic careers. What makes YES special is the sense of community, the breadth and depth of mentorship, and focus on methodological rigor as a foundation to translational and policy-relevant research.”
