American Board of Internal Medicine Internal Medicine Certification Examination

The American Board of Internal Medicine Internal Medicine Certification Examination is a specialty board examination for physicians seeking initial certification in internal medicine. It assesses whether candidates can apply internal medicine knowledge and clinical judgment to patient care; it is not an entrance exam for medical school or residency. Candidates generally complete qualifying internal medicine residency training and meet ABIM requirements for licensure and professional standing. Because eligibility pathways and policies can change, physicians planning for the 2027–2028 cycle should confirm their status and requirements directly with ABIM.

The exam uses clinical scenarios to assess decision-making across the breadth of internal medicine, including cardiovascular disease, pulmonary disease and critical care, gastroenterology and hepatology, and nephrology and electrolyte disorders. Candidates should also review other major areas of general internal medicine rather than concentrating only on a few subspecialties. The certification exam is computer-based and organized into timed sections; check ABIM’s current exam information for the applicable format and timing. Preparation typically involves blueprint-guided review, applying evidence to cases, and revisiting gaps identified through self-assessment.
