The American Board of Medical Specialties (ABMS) is a non-profit organization that oversees the certification of physician specialists in the United States. Established in 1933, it aims to improve healthcare quality by ensuring that doctors meet specific standards of training and knowledge in their respective fields. ABMS comprises 24 member boards, each representing a medical specialty, such as internal medicine and pediatrics. These boards develop and administer certification exams, which physicians must pass to demonstrate their expertise. The certification process helps patients identify qualified specialists and promotes ongoing education and professional development among physicians.
