A current guide to COMLEX-USA Level 3, including the NBOME/Pearson VUE delivery process, two-day format, 420 multiple-choice questions, 26 Clinical Decision-Making cases, 14-day scheduling window, and 2027 one-day transition note.
Level 3 assesses readiness for unsupervised osteopathic medical practice. Preparation needs both standard multiple-choice pacing and CDM case decision-making across data acquisition, diagnosis, treatment, management, counseling, and follow-up.
Use these points before scheduling COMLEX-USA Level 3 or planning residency-era review.
COMLEX-USA Level 3 is administered by NBOME and scheduled through the NBOME/Pearson VUE process.
NBOME lists Level 3 as a two-day computer-based examination administered within a 14-day window.
The current exam has four 3.5-hour sessions, with two sessions per day.
Level 3 includes 420 single-best-answer multiple-choice questions and 26 Clinical Decision-Making cases.
CDM questions may use extended multiple-choice or short-answer formats and focus on management decisions.
NBOME states Level 3 will transition to a one-day, eight-hour examination starting in January 2027.
Level 3 is not only a multiple-choice exam. CDM cases ask candidates to make patient-management decisions, often through extended multiple-choice or short-answer formats that reward precise diagnosis, workup, treatment, and follow-up choices.
The current format uses two testing days within a 14-day window, with two 3.5-hour sessions per day. Day 1 is MCQ-heavy, while Day 2 includes CDM cases plus additional MCQ sections.
NBOME frames Level 3 around readiness for unsupervised osteopathic medical practice. Review should emphasize safe management, escalation, counseling, follow-up, OPP, systems-based practice, professionalism, and ethics.
Candidates testing in or after January 2027 should verify the current NBOME format, because Level 3 is scheduled to move from the two-day structure to a one-day, eight-hour examination.
