Certification Portfolio and Target Audience
American Board of Internal Medicine (ABIM) offers credentials across initial certification and Maintenance of Certification (MOC) tracks, including the innovative Longitudinal Knowledge Assessment (LKA®) option:
- Internal Medicine (Initial Certification) – Entry-to-professional level for residents completing ACGME-accredited training. Validates foundational competencies across all aspects of adult patient care.
- Subspecialty Certifications (e.g., Cardiovascular Disease, Gastroenterology, Hematology, Infectious Disease, Nephrology, Pulmonary Disease, Rheumatology, Endocrinology, Oncology, Critical Care Medicine, and 10+ more) – Advanced professional and subspecialty credentials requiring additional fellowship training (typically 1–3 years).
- Maintenance of Certification (MOC) – Ongoing assessment via traditional 10-year exam or the flexible LKA® (quarterly questions, open-book, no test center required for most).
Target Audience: Physicians who have completed internal medicine residency or subspecialty fellowships. Ideal for hospitalists, primary care internists, academic physicians, and specialists. ABIM certification is required or strongly preferred for most hospital privileges, academic appointments, and insurance panel participation.
Industry Recognition: As an ABMS member board, ABIM certifications are the gold standard in internal medicine. They are recognized by hospitals, insurers, state medical boards, and employers nationwide. Certified physicians appear in virtually every job posting for internal medicine roles and command premium salaries and career mobility.
