ABIM Infectious Disease

It is a computer-based, multiple-choice exam with single best answer questions; some questions may include case vignettes or multimedia-style stems. ABIM publishes the current format, including any changes to question style or delivery, on its website, so check there rather than relying on secondhand descriptions.

ABIM publishes the current question count, section structure, and total testing time for each exam, and these details change periodically. Do not rely on numbers from older study guides; consult the official ABIM exam description for the authoritative figures before you plan your pacing.

It is broad rather than obscure. Questions often test judgment in common scenarios: when to broaden coverage, when to narrow, when to image, and when to call it colonization. Fellows who have managed a diverse inpatient and transplant service and reviewed guidelines systematically generally find it manageable; those who only memorized drug lists struggle.

Start with a blueprint-driven content pass weighted toward bacterial infections and antimicrobial therapy, since that domain carries the largest share. Then layer in HIV, immunocompromised host, and diagnostics. Finish with timed case-based practice, reviewing every wrong answer for the underlying reasoning, not just the fact.

Overstudying rare organisms at the expense of common ones, ignoring stewardship and diagnostic reasoning, misreading stems that ask for the next best step versus the diagnosis, and running out of time because of untimed practice. Poor test-taking pacing and skipping guideline updates in rapidly changing areas also cost points.

ABIM sets its own rules for retake eligibility, waiting periods, and any limits on attempts. These policies are subject to change, so verify the current requirements and any associated deadlines directly on the ABIM website rather than assuming a fixed window.

ABIM determines the passing standard for each exam and publishes the current scoring and reporting information on its site. This page deliberately does not state a score, percentile, or pass rate, because those figures are updated and should be confirmed from the official source.

Use the ABIM blueprint to define scope, current society guidelines for management standards, a comprehensive infectious disease review text or lecture series for breadth, and a large bank of case-based questions for application. Prioritize resources that explain reasoning and cite guideline sources over pure fact-recall decks.

ABIM maintains certification through its maintenance of certification program, which involves ongoing assessment and continuing education rather than a single lifetime credential. The specific requirements and assessment options evolve, so check the current ABIM maintenance of certification information for your enrollment year.
