CPM/AM Exam Dates for 2026
If you're planning your year around the Primary Certification in Aerospace Medicine (CPM/AM) exam administered by the American Osteopathic Board of Preventive Medicine (AOBPM) under the American Osteopathic Association (AOA), the date to circle is October 15, 2026. Both the written examination and the separate oral examination are scheduled for that same date, which means candidates need to plan for a single, concentrated testing day rather than two separate travel or scheduling windows spread across the year.
Because the written and oral components are administered together on the same date, there's no flexibility to sit for one now and defer the other to a later cycle within the same year. Candidates preparing for both should treat October 15 as a single high-stakes day requiring readiness across the full content blueprint, not just the multiple-choice portion. For a breakdown of what's actually tested, see the CPM/AM Exam Domains 2026 guide.
Registration Timeline and Deadlines
Registration for the 2026 administration opened on May 1, giving candidates roughly four and a half months to submit their application before the regular deadline closes. The key dates are:
- May 1, 2026 - Registration opens
- September 20, 2026 - Regular registration deadline
- September 27, 2026 - Final late registration deadline (no further extensions)
- October 15, 2026 - Written and oral examinations administered
That's a narrow one-week window between the regular deadline and the absolute final cutoff, so candidates who miss September 20 have very little room for error. Given that October 15 sits less than a month after the final late deadline, there is minimal runway between confirming your seat and sitting for the exam - plan your board-review schedule accordingly rather than assuming you can register at the last minute and still have adequate preparation time.
| Milestone | 2026 Date |
|---|---|
| Registration opens | May 1 |
| Regular deadline | September 20 |
| Final late deadline | September 27 |
| Written exam (100 core + 100 specialty questions, 4 hours) | October 15 |
| Oral exam (approx. 45 minutes) | October 15 |
Key Takeaway
Register before September 20 if at all possible. The September 27 date exists as a safety net, not a planning target, and it carries a financial penalty on top of the compressed timeline.
Exam Fees and Late Penalties
Standard examination fees for the 2026 cycle total $1,600, split evenly between the two components: $800 for the written exam and $800 for the oral exam. Candidates who register after the regular September 20 deadline but before the final September 27 cutoff pay a late fee of $240 per component - meaning a candidate registering late for both the written and oral exams could add up to $480 on top of the standard $1,600.
If cost is a major factor in your planning, it's worth reviewing the full fee structure - including how these charges compare to ongoing certification maintenance costs - in the CPM/AM Certification Cost breakdown. Registering early isn't just about securing a testing slot; it's a straightforward way to avoid an entirely avoidable expense.
What Test Day Looks Like
The CPM/AM written exam is administered as a timed, remote-proctored assessment using MonitorEDU proctoring software running on the PARADIGM examination platform. Candidates should expect the standard remote-testing protocols: identity verification, workspace checks, and continuous monitoring throughout the session.
The written exam itself consists of 200 multiple-choice questions delivered in four hours, structured in two distinct blocks:
- 100 core questions in a two-hour block
- 100 specialty questions in a separate two-hour block
The platform provides an on-screen calculator, a digital scratchpad, and laboratory reference values - tools candidates should familiarize themselves with before test day, since fumbling through an unfamiliar interface under time pressure wastes minutes you don't have in a four-hour, 200-question exam.
The oral examination is administered separately from the written blocks and runs approximately 45 minutes. It assesses clinical reasoning and communication in ways a multiple-choice format cannot, so candidates should not treat oral preparation as an afterthought squeezed in during the final week before October 15.
To understand how the exam's passing standard is calculated and what a competitive scaled score looks like, review the CPM/AM Passing Score guide, which explains the 500-point threshold on the 200-800 scale used for initial certification.
Key Takeaway
Practice with a timer that mirrors the real structure - two separate two-hour blocks, not one undifferentiated four-hour session - so your pacing instincts match the actual exam day format.
Domain Weighting You're Scheduling Around
Your study calendar between now and October 15 should be built around the AOBPM's published content-weighting table, not an even split across topics. The six domains and their approximate weights are:
Domain 4: Clinical Aerospace Medicine - 45%
This is by far the largest portion of the content table and deserves the largest share of your study calendar. Note that this 45% reflects weighting within the domain table itself, not 45% of all 200 combined written items.
- Physiologic effects of altitude, acceleration, and hypoxia on aircrew
- Medical certification standards and disqualifying conditions
- Clinical management of conditions specific to flight environments
Domain 3: Civil Regulation - 20%
Regulatory knowledge is the second-heaviest domain and covers the frameworks aerospace medicine physicians must apply when making certification decisions.
- Civil aviation medical certification processes
- Regulatory standards governing aircrew fitness for duty
Domain 2: Biomechanics - 15%
Covers the physical forces acting on the human body during flight, including impact, vibration, and acceleration effects.
Domain 6: Specialized Areas - 10%
Encompasses niche but testable topics that don't fit neatly into the larger domains.
Domain 5: Environment of Flight - 7%
Covers environmental stressors specific to the aerospace setting, distinct from the clinical management topics tested in Domain 4.
Domain 1: History - 3%
The smallest domain by weight, but still a scored component of the exam.
For a full walkthrough of each domain's subtopics and testable detail, see the CPM/AM Exam Domains 2026 guide. If you're still weighing whether the overall content load matches your background, the How Hard Is the CPM/AM Exam guide breaks down difficulty factors in more detail.
Building a Study Calendar Around October 15
With registration deadlines landing in late September and the exam itself in mid-October, most candidates realistically have a summer-through-fall preparation window. Rather than studying domains in the order they appear on the content outline, allocate time proportional to weight - meaning Clinical Aerospace Medicine and Civil Regulation should consume the bulk of your calendar, with History and Environment of Flight receiving lighter, later-stage review.
Clinical Aerospace Medicine Foundations
- Build core knowledge in altitude physiology, certification standards, and disqualifying conditions
- Work through practice questions targeting the 45%-weighted domain first, since it carries the most scoring impact
Civil Regulation Deep Dive
- Study certification frameworks and regulatory standards specific to aircrew fitness
- Pair regulation review with clinical case scenarios to reinforce cross-domain connections
Biomechanics, Specialized Areas, and Environment of Flight
- Cover the mid-weight and lower-weight domains in sequence
- Begin timed practice blocks mirroring the two-hour core/two-hour specialty structure
Oral Exam Rehearsal and Full Review
- Practice verbal case presentations for the approximately 45-minute oral component
- Run full-length timed simulations on a platform resembling PARADIGM's interface, including calculator and scratchpad tools
For a more detailed week-by-week methodology, including how to sequence practice exams and review sessions, see the CPM/AM Study Guide 2026. Reinforcing your preparation with realistic practice questions on our practice test platform can help you gauge readiness against the actual four-hour, 200-question format before you commit to the October 15 date.
Eligibility Checks Before You Register
Before you submit payment for the May 1 registration window, confirm you meet AOBPM's eligibility requirements - discovering a gap after registering wastes both time and the non-refundable portions of your fee. Requirements include:
- A COCA-accredited osteopathic degree, or a qualifying LCME-accredited medical degree from the US or Canada, or qualifying international medical education with valid ECFMG certification
- Unrestricted medical licensure in a US state or territory
- Completion of the board-specified two-year ACGME training sequence: one year in aerospace medicine and one transitional year
- An MPH or equivalent postgraduate degree covering biostatistics, epidemiology, health services management, and environmental health
- Compliance with AOBPM's ethical standards
A full explanation of each requirement, including how the training sequence and degree requirements interact, is available in the CPM/AM Requirements 2026 guide.

Scholarship Deadline Considerations
AOCOPM offers first-attempt board-exam scholarships that can cover eligible application, written, and oral fees for candidates who have an accepted AOBPM application and do not already hold an AOA board certification. Reimbursement requires receipts, so candidates pursuing this option should register and pay the standard fees on the normal timeline, then submit documentation afterward rather than waiting on scholarship approval before registering. Given the compressed window between the September 20 regular deadline and the October 15 exam, building scholarship paperwork into your fall schedule early avoids last-minute administrative stress on top of exam preparation.
After the Written Exam: OCC and Annual Deadlines
Passing the written and oral exams on October 15, 2026 is the entry point, not the finish line. The initial certificate is active for two years, after which candidates enter annual reverification through Osteopathic Continuous Certification (OCC), including longitudinal assessment beginning in the certificate's expiration year. That annual assessment is a 15-question, untimed, open-book test requiring a 75% passing standard, with reattempts available; it carries a $150 annual fee, plus a $50 late fee if missed. Separately, OCC requires 60 CME credits across the 2025-2027 three-year cycle, including 24 specialty-specific credits, active licensure, and attestation to quality-improvement participation.
Because these recurring deadlines stack on top of the initial exam date, it's worth mapping out the full certification lifecycle before you register. The CPM/AM Certification Cost breakdown covers how initial fees compare to ongoing renewal costs, and the Is the CPM/AM Certification Worth It? ROI analysis weighs the long-term time and cost commitment against career benefits. For a sense of who actually hires CPM/AM-certified physicians once you're through the process, see CPM/AM Jobs.
Frequently Asked Questions
Both the written and oral examinations are scheduled for October 15, 2026. Registration opened May 1, with a regular deadline of September 20 and a final late deadline of September 27, 2026.
The published schedule lists both the written and oral examinations on the same October 15, 2026 date, and standard fees are broken out per component ($800 written, $800 oral), so candidates should plan to prepare for both on the same day.
You can still register through the final late deadline of September 27, 2026, but a late fee of $240 per component applies, meaning registering late for both the written and oral exams adds up to $480 to the standard $1,600 fee.
Yes. The AOA's remote-testing guidance specifies MonitorEDU proctoring on the PARADIGM examination platform, which includes an on-screen calculator, a digital scratchpad, and laboratory reference values during the test.
It totals 200 multiple-choice questions across four hours, split into a 100-question core section (two hours) and a 100-question specialty section (two hours). The separate oral exam runs approximately 45 minutes.
