The Next Announced Testing Window
If you're planning around Certification in Osteopathic Emergency Medicine (AOBEM), the date that matters most right now is March 22-24, 2027 - the next announced administration of the Emergency Medicine Part I Written Exam. This is the initial certification exam, not the separate CORE continuing-certification assessment that active diplomates complete annually. Everything in this article is scoped to that written exam.
Unlike a single-day test, AOBEM's written exam window spans three days, which affects how candidates get scheduled into a specific session, how travel or remote-testing logistics get arranged, and how last-minute eligibility documentation gets resolved. If you're still confirming whether you qualify, start with our EM Requirements 2026: Eligibility, Prerequisites & How to Qualify guide before locking in a date.
How AOBEM Scheduling Actually Works
Scheduling for the AOBEM written exam isn't a simple "pick any day" system. Eligibility has to be established first - through approved emergency-medicine residency training, required licensing documentation, and professional/ethical compliance review - before a candidate can register into an announced window. Graduates and final-year residents who have completed at least 80% of residency training are described as eligible on AOBEM's written-exam eligibility page, so many candidates sit the written exam during their final year rather than waiting until after graduation.
Because the written and oral examinations may be taken in either order once each exam's own eligibility conditions are met, some candidates sit the written exam first during residency and save the oral exam for after residency is fully complete (oral eligibility requires completed residency). Others do the reverse if their program and documentation timeline favors it. Either way, full certification isn't awarded until both examination stages are finished and AOA approval is granted.
Key Takeaway
Don't wait until residency graduation to check written-exam eligibility - the 80%-of-training threshold means many residents can and do register for an earlier announced window.
Exam Day Structure: Six Sections, Six Hours
Knowing the exact shape of test day changes how you pace your final review. The AOBEM Part I Written Exam contains 300 multiple-choice questions, mostly one-best-answer items with five answer options, split into six sections of 50 questions each, with 60 minutes allotted per section. That's six hours of active testing time, and that figure excludes the optional 10-minute breaks between sections and an optional 40-minute lunch break after Section 3.
A critical logistics detail: once a section is closed, you cannot return to it. There's no going back to recheck a flagged question from Section 2 once you've moved to Section 3. Electronics and study materials are prohibited during any break, including the lunch break, so plan your break time as genuine rest rather than a last-minute review opportunity.
- Total questions: 300, divided into six 50-question sections
- Time per section: 60 minutes, non-transferable between sections
- Breaks: Optional 10-minute breaks between sections; optional 40-minute lunch after Section 3
- Section lock: No re-entry once a section closes
For a full breakdown of what's actually tested inside those 300 questions, see EM Exam Domains 2026: Complete Guide to All 18 Content Areas. And if you're wondering whether this format is genuinely tough or just long, How Hard Is the EM Exam? Complete Difficulty Guide 2026 breaks down the difficulty factors beyond raw question count.
Why Section Pacing Matters More Than Total Time
With 50 questions in a fixed 60-minute section, you have roughly 72 seconds per question if you want to finish with review time. Because sections lock permanently, a slow start in Section 1 can't be recovered later - practice pacing by section, not just by full-length exam.
- Time yourself in 50-question blocks during practice, not only in full 300-question sittings
- Flag-and-move discipline matters more here than in untimed study
Remote Proctoring Logistics You Must Confirm Early
The AOBEM written exam is delivered as a remotely proctored exam through AOA MonitorEDU/PARADIGM arrangements. This isn't a walk-in testing center model - candidates need a compatible computer, a compatible mobile device, a private testing space, and a properly configured secure browser installed and tested in advance.
Because this is remote proctoring rather than in-person testing, technical failures on exam day are a real risk if you haven't rehearsed the setup. Confirm your equipment compatibility, internet stability, and private-room arrangements well before the March 22-24, 2027 window - not the night before.
Building a Study Timeline Around the Testing Window
Once you know your target session, work backward using the exam blueprint's own weighting rather than a generic content list. Abdominal and gastrointestinal disorders and Cardiovascular disorders are jointly the largest domains at 9% each, followed by Traumatic disorders at 8%. Those three domains alone account for roughly a quarter of the exam, so they deserve proportionally more early review time than smaller domains like Cutaneous disorders (3%) or EMS, disaster medicine and administrative aspects of emergency medicine (2%).
A spaced-repetition approach works well here specifically because AOBEM's blueprint is public and weighted - you can allocate review sessions in proportion to domain percentage rather than splitting time evenly across all 18 areas. Full domain-by-domain descriptions and study priorities are covered in EM Exam Domains 2026: Complete Guide to All 18 Content Areas, and a broader first-attempt strategy is laid out in EM Study Guide 2026: How to Pass on Your First Attempt.
High-weight domains first
- Abdominal/GI disorders (9%) and Cardiovascular disorders (9%)
- Traumatic disorders (8%)
Mid-weight systems
- Systemic infectious disorders (7%), Nervous system disorders (7%), Thoracic-respiratory disorders (7%)
- Obstetrics and gynecology disorders (6%), Procedures/skills (6%)
Remaining 5% domains
- Endocrine/metabolic/nutritional, HEENT, Musculoskeletal (nontraumatic), Renal/urogenital, Toxicological disorders/clinical pharmacology
Lower-weight domains and full timed sections
- Environmental disorders, Psychobehavioral disorders, Hematologic/immune, Cutaneous, EMS/disaster/administrative
- Full 50-question timed section practice on ../
Key Takeaway
Match study hours to domain percentage weight, not to how many topics fall under each domain - 9% domains deserve roughly three times the review time of a 3% domain.
Sequencing the Written and Oral Exams
Because the written and oral exams can be taken in either order once eligibility conditions are met, scheduling decisions aren't purely about the written exam's calendar. Oral exam eligibility requires completed residency, while written exam eligibility only requires 80% of training completed - which is why many candidates schedule the written exam earlier, sometimes during final-year residency, and the oral exam afterward.
| Component | Fee | Format | Eligibility Timing |
|---|---|---|---|
| Part I Written Exam | $1,100 | 300 MCQs, six 50-question sections, remote proctoring | At least 80% of residency training complete |
| Part II Oral Exam | $800 | Separate oral examination stage | Residency must be fully complete |
| OCC / CORE (post-certification) | $210 annual | Open-book, 40-60 questions across core and selected modules | Ongoing after full certification is achieved |
Full certification isn't awarded until both the written and oral stages are complete and the AOA has approved the candidate - passing the written exam alone doesn't finish the process. For a complete cost breakdown across both stages, see EM Certification Cost 2026: Complete Pricing Breakdown.
Fees, Deadlines, and Budget Planning
The written examination fee is $1,100, separate from the $800 oral exam fee - treat these as two distinct budget line items rather than one combined certification cost. Passing score on the written exam is 500 on a 200-800 scaled-score range; details on exactly what that means for raw performance are covered in EM Passing Score 2026: Exactly What You Need to Pass.
Once you're fully certified and enter Osteopathic Continuous Certification, budgeting shifts to an annual model: a $210 annual OCC fee covering CORE participation, active licensure maintenance, 60 CME credits per three-year cycle, and two practice-performance improvement projects across a ten-year span (one per five-year half). CORE completion is due December 1 each year and replaces the older ten-year high-stakes recertification exam model - new certificants enter this annual CORE pathway automatically rather than facing a decade-later high-stakes retest.
For context on how the written exam's difficulty and pass outcomes are typically reported, review EM Pass Rate 2026: What the Data Shows, which explains why published pass-rate figures are aggregated data rather than single-year snapshots.
Final Registration Prep Before March 2027
With a three-day window (March 22-24, 2027) rather than a single test date, confirm early which specific day you're assigned to, since remote-proctoring slot availability can vary within the window. Build your equipment testing, private-space confirmation, and final content review around your specific assigned day rather than the window's first date by default.
Use full-length, sectioned practice tests that mirror the 50-question/60-minute structure to build stamina for six total hours of active testing. Practicing on our AOBEM-aligned practice platform lets you rehearse the section-lock format so the real exam's "no going back" rule doesn't cost you points on test day.

Frequently Asked Questions
The next announced administration is March 22-24, 2027, delivered as a remotely proctored exam through AOA MonitorEDU/PARADIGM arrangements.
Yes. Written-exam eligibility is available once a candidate has completed at least 80% of an approved emergency-medicine residency, so many candidates sit it during final-year residency.
Six hours of active testing across six 50-question sections at 60 minutes each, not counting optional 10-minute breaks between sections or the optional 40-minute lunch after Section 3.
No. The written and oral exams may be taken in either order once each one's own eligibility conditions are met, though the oral exam requires residency to be fully complete first.
Nothing can be done - once a section closes, candidates cannot return to it, so review and flagged questions must be resolved before moving to the next section.
