The ABMM exam leads to the American Board of Medical Microbiology (ABMM) Diplomate certification from American Society for Microbiology (ASM). It is positioned at the Professional / Expert level. The exam validates the knowledge and skills expected of candidates preparing for American Society of Microbiology ABMM.

The ABMM exam includes 200–220 questions and allows 240 minutes. Before test day, divide the available time by the number of questions in a timed practice set to establish a steady per-question pace. If a difficult item starts consuming too much time, mark it for review and move forward instead of losing momentum. A full timed practice session can help you decide when to move on, when to return, and how much buffer to reserve for a final check.

The passing score for ABMM is Criterion-referenced, determined per exam form, and the official exam fee is $450 (ASM members), $575 (non-members). Because a retake requires paying the exam fee again, use timed practice results as a readiness check before scheduling your next attempt. If your performance remains inconsistent, continue reviewing weak domains and repeat a timed session before booking the exam.

Doctoral degree in microbiology or related field; plus 3 years of experience, or 2 years CPEP training, or completion of ACGME/CCM/RCPSC-accredited fellowship/residency
