The Pathway to Osteopathic Medical Practice & Licensure in the United States
COMLEX-USA (Comprehensive Osteopathic Medical Licensing Examination of the United States) is a three-level, national standardized licensure examination designed for licensure for the practice of osteopathic medicine. COMLEX-USA is designed to assess osteopathic medical knowledge, knowledge fluency, clinical skills, and other competencies essential for practice as an osteopathic generalist physician. It is also a graduation requirement for attaining a DO (Doctor of Osteopathic Medicine) degree from colleges of osteopathic medicine in the United States, and for entry into and promotion within graduate medical education (residency) training programs.
