Initial Certification indicates that physicians have met rigorous standards through intensive study, accredited training and evaluation and that they have the clinical judgment, skills and attitudes essential for the delivery of excellent patient care.

MOC is a professionally determined standard that attests that an internist is staying current in knowledge and practice throughout his/her career.

For more than 75 years, Certification by ABIM has stood for the highest standard in internal medicine and its 20 subspecialties.
