To enhance the quality of health care by certifying internists and subspecialists who demonstrate the knowledge, skills and attitudes essential for excellent patient care.
Certification by the American Board of Internal Medicine
Since its founding in 1936 to answer a public call to establish more uniform standards for physicians, Certification by the American Board of Internal Medicine (ABIM) has stood for the highest standard in internal medicine and its 21 subspecialties. Certification has meant that internists have demonstrated – to their peers and to the public – that they have the clinical judgment, skills and attitudes essential for the delivery of excellent patient care.
ABIM is not a membership society, but a physician-led, non-profit, independent evaluation organization. Our accountability is both to the profession of medicine and to the public.
