Validity Evidence for the Emergency Medicine Standardized Letter of Evaluation.

Background: The standardized letter of evaluation (SLOE) is the application component that program directors value most when evaluating candidates to interview and rank for emergency medicine (EM) residency. Given its successful implementation, other specialties, including otolaryngology, dermatology, and orthopedics, have adopted similar SLOEs of their own, and more specialties are considering creating one. Unfortunately, for such a significant assessment tool, no study to date has comprehensively examined the validity evidence for the EM SLOE.
