Frequently Asked Questions

What are the eligibility requirements to sit for the ABIM Infectious Disease Certification Exam?

Candidates must hold prior certification in Internal Medicine or Pediatrics through the ABIM or the American Board of Pediatrics (ABP). They must also have successfully completed a minimum of 24 months of fellowship training in an ACGME-accredited Infectious Disease program. Additionally, candidates must demonstrate clinical competence in the required procedural and patient care skills as attested by their fellowship program director.

How is the exam structured and what is the format?

The exam is a one-day, computer-based test consisting of approximately 240 single-best-answer, multiple-choice questions. These questions are divided into four sessions. The content assesses knowledge across the entire certification blueprint, focusing on clinical diagnosis, management, and foundational science. Questions are designed to evaluate diagnostic reasoning, judgment, and the application of knowledge to patient care scenarios.

How often must I maintain my certification, and what does Maintenance of Certification (MOC) involve?

ABIM certification is time-limited. Diplomates participate in the ABIM's Maintenance of Certification (MOC) program, which requires ongoing engagement in medical knowledge, practice assessment, and continuous learning. This includes earning a minimum number of Medical Knowledge and Practice Assessment MOC points every 2-5 years, and passing a secure MOC assessment (exam or other approved activity) at least every 10 years to maintain certified status.

What are the key content areas covered on the exam blueprint?

The official blueprint outlines major categories including: Microbial Pathogenesis and Antimicrobial Therapy; Clinical Syndromes (e.g., febrile syndromes, CNS infections, cardiovascular infections); Organ System-Based Infections; Infections in Special Hosts (immunocompromised, surgical, critical care); HIV/AIDS and Related Disorders; Mycobacterial, Fungal, and Parasitic Diseases; Healthcare Epidemiology, Infection Prevention, and Occupational Health. A detailed blueprint is available on the ABIM website.

What is the pass rate for the Infectious Disease Certification Exam?

Pass rates vary annually but are historically consistent with other ABIM subspecialty certifications, typically ranging for first-time takers from the mid-80s to low-90s percentile. The ABIM does not publish a specific numerical target; the passing standard is determined through a rigorous standard-setting process by a committee of expert infectious disease physicians.
