The American Board of Internal Medicine (ABIM) is the physician-run organization that sets the standards for certification and recertification of internists and subspecialists. The ABIM Maintenance of Certification (MOC) is designed to ensure that internists continue to be competent in their field over their practice lifetime. Setting standards for our own profession—as opposed to having standards set by others outside the profession—is a privilege based on societal trust. The public expects physicians to keep up-to-date in our medical knowledge and to demonstrate this competence through regular testing.1
