EM Pass Rate 2026: What the Data Shows

What the 93.63% Pass Rate Actually Means

Anyone researching Certification in Osteopathic Emergency Medicine eventually runs into the same number: 93.63%. It's the pass rate published by the American Osteopathic Board of Emergency Medicine (AOBEM) for the initial Emergency Medicine Part I Written Exam. That figure sounds reassuring, and in a broad sense it is - most board-eligible residency graduates who sit for the exam do pass. But the number is easy to misread if you treat it as a guarantee rather than a data point.

This article focuses specifically on the AOBEM Part I Written Exam, the entry point into osteopathic emergency medicine certification. It is not the same assessment as the separate Part II Oral Exam, and it is not the same as the CORE continuing-certification process that certificants complete every year after they're already boarded. If you're comparing pass-rate data across sources, make sure you know which exam the number is attached to.

Why It's a Five-Year Aggregate, Not a Single-Year Score

The 93.63% pass rate represents first-time, board-eligible examinees aggregated across five years, not a single testing cycle. That distinction matters for two practical reasons.

• Single-year swings get smoothed out. A five-year aggregate absorbs variation between any one administration and the next, so it tells you about the exam's general difficulty over time rather than what happened in March 2026 specifically.
• "First-time, board-eligible" is a specific population. It excludes retakes and candidates who tested outside standard eligibility pathways. If you're not sitting for the first time under full board eligibility, your personal odds may look different from the published aggregate.

None of this is meant to undercut the number - it's a legitimate, transparent statistic. It just isn't a promise about any individual candidate's outcome in any individual year. For a deeper look at how difficulty is distributed across content, see the complete EM exam difficulty guide, and for the score mechanics behind "passing," check exactly what you need to pass.

Inside the 300-Question Written Exam

Pass-rate data is only meaningful once you understand what candidates are actually up against. The AOBEM Part I Written Exam is built from 300 multiple-choice items, mostly one-best-answer questions with five answer options. It's divided into six sections of 50 questions each, with 60 minutes allotted per section - six hours of active testing time in total, not counting breaks.

• An optional 10-minute break is available between sections.
• An optional 40-minute lunch break follows Section 3.
• Once a section closes, you cannot go back into it - there's no revisiting earlier questions after time expires or you submit.
• Electronics and study materials are prohibited during any break period.

Delivery is remotely proctored through the AOA's MonitorEDU/PARADIGM arrangement. That means candidates need a secure-browser setup, a compatible computer and mobile device, and a private, distraction-free testing space arranged in advance. Technical dry runs before test day are not optional extras - they're part of avoiding an avoidable failure that has nothing to do with medical knowledge.

The Domains Most Likely to Decide Your Outcome

The written exam draws from 18 content domains that together total 100% of the blueprint. Two domains tie for the largest share at 9% each: Abdominal and gastrointestinal disorders and Cardiovascular disorders. Traumatic disorders follows close behind at 8%. Together, these three domains account for roughly a quarter of the entire exam - which makes them the highest-leverage areas for study time.

The remaining domains - from Systemic infectious disorders and Nervous system disorders (7% each) down through smaller domains like Cutaneous disorders and EMS/disaster medicine (2-3% each) - still add up to more than half the exam collectively, so they can't be ignored. A full breakdown of every content area, including weighting and typical question style, is available in the complete guide to all 18 EM exam domains.

How Eligibility and Timing Feed Into the Rate

Pass-rate data is easier to interpret once you understand who's actually eligible to sit for the exam. Candidates need approved emergency-medicine residency training, required licensing documentation, and demonstrated professional and ethical compliance. Importantly, the written exam can be taken once a candidate has completed at least 80% of residency training - the eligibility criteria describe both graduates and final-year residents as qualified populations.

The written and oral examinations can be taken in either order once each one's specific eligibility conditions are met, but residency must be fully complete before sitting for the Part II Oral Exam. Full certification isn't granted until both stages are finished and formally approved by the AOA. If you're still mapping out whether you qualify, the EM requirements guide walks through eligibility and prerequisites in detail.

AOBEM vs. ABEM: Two Different Pathways

A common source of confusion is assuming all emergency medicine board credentials are interchangeable. They're not. This site, and this article, are specifically about the American Osteopathic Board of Emergency Medicine (AOBEM) certification pathway - its own written exam, its own blueprint, its own fee structure, and its own continuing-certification process (CORE). Other emergency medicine boards operate independently, with separate exam content, separate fee schedules, and separate pass-rate reporting.

If you've seen pass-rate figures, question counts, or fee numbers elsewhere that don't match what's described here, you're likely looking at a different credential entirely. When in doubt, confirm which certifying body's published materials you're reading before applying any number to your own exam planning.

Registration, Fees, and the Next Testing Window

The written exam carries a fee of $1,100 (USD). The separate Part II Oral Exam has its own fee of $800. These are distinct payments tied to distinct stages of the certification process, so budgeting for both - not just the written exam - is part of realistic planning. A full cost breakdown, including how these fees fit into the broader certification timeline, is covered in the EM certification cost guide.

The next announced written examination window is March 22-24, 2027. Because sections close permanently once time expires and the exam is delivered under remote-proctoring conditions, registration logistics - confirming your testing space, your device compatibility, and your application status - deserve attention well before test week. See the EM exam dates guide for the full testing calendar and deadline structure.

Building a Domain-Weighted Study Timeline

Generic study advice - spaced repetition, timed practice blocks, active recall - only helps if it's applied against the right content in the right order. For the AOBEM written exam, that means allocating study time roughly proportional to domain weight, not equally across all 18 areas.

The point of front-loading Abdominal/GI, Cardiovascular, and Trauma isn't that other domains don't matter - it's that mastery of the heaviest-weighted content gives you the most points per hour invested. For a structured, week-by-week version of this approach with more detail, see the EM study guide for passing on your first attempt. You can also reinforce section-pacing and question-style familiarity using timed practice sets on the main practice test platform.

Written Exam vs. CORE: Don't Confuse the Two

Once certified, AOBEM diplomates don't take a single high-stakes recertification exam every ten years the way earlier generations of certificants did. Instead, new certificants enter the Osteopathic Continuous Certification (OCC) pathway, which includes CORE - an annual, open-book assessment made up of two required core modules and four selected article modules, totaling 40-60 questions. CORE requires 75% on each module, allows two attempts separated by one week, and is due each year by December 1.

OCC also requires active licensure, 60 CME credits per three-year cycle, and two practice-performance improvement projects across a ten-year span (one in each five-year half), all covered under a $210 annual fee that includes CORE. None of CORE's open-book or retry rules apply to the initial Part I Written Exam - that exam is a single, closed-book, proctored sitting with no retry mechanism within the same administration. Keeping these two processes mentally separate prevents a lot of unnecessary confusion when researching pass rates, since CORE doesn't report a comparable "pass rate" the way the written exam does.

For candidates weighing whether the full certification pathway - written exam, oral exam, and ongoing OCC/CORE obligations - is worth the investment, the ROI analysis on EM certification and the EM salary guide lay out the career-side considerations. You can build broader exam-day familiarity ahead of time using full-length timed practice exams that mirror the six-section written exam format.
