UHM Exam Dates 2026: Testing Windows, Deadlines & Scheduling

Why 2026 Exam Dates Aren't Posted the Way You'd Expect

If you've been searching for a clean list of "2026 UHM exam dates," you've probably noticed something frustrating: the official examination page for AOA Subspecialty Certification in Undersea and Hyperbaric Medicine retains scheduling text from a prior cycle. That old date is not a 2026 testing appointment, and candidates who plan around it risk missing the actual application window entirely.

This isn't unusual for smaller osteopathic subspecialty boards administered through the AOA's Conjoint Examination Committee structure. Unlike high-volume certifying bodies that run rolling computer-based testing windows year-round, the UHM written examination is scheduled less frequently, and the committee updates its page on its own timeline. The practical implication for anyone preparing in 2026 is simple: you must confirm the current administration date directly with the American Osteopathic Association before locking in a study plan or travel arrangements.

How the AOA Conjoint Examination Committee Handles Scheduling

The written examination for this credential is administered under the American Osteopathic Conjoint Undersea & Hyperbaric Medicine Examination Committee, operating within the broader AOA board certification system. This is distinct from other exams that share the "UHM" abbreviation, and it's also distinct from the separate ABPM/ABEM pathway examination - this article, and the certification it discusses, refers specifically to the AOA initial written examination administered through this conjoint committee.

Because the candidate pool for this subspecialty is relatively small compared to primary-board examinations, the committee doesn't operate a continuous testing calendar. Instead, administrations are set periodically, and eligibility verification happens before a candidate is cleared to sit. That sequencing matters: your actual test date is gated by how quickly your application, fellowship documentation, and treatment logs clear review - not just by which day happens to be open on a calendar.

Application Timeline: What Must Be Ready Before You Register

Because scheduling is tied to a documentation-heavy application, most of the "timeline" work for this exam happens before a date ever gets confirmed. The published application requirements include:

• A current curriculum vitae
• Proof of unrestricted medical licensure
• Documentation of your one-year AOA- or ACGME-approved hyperbaric medicine fellowship
• Evidence of primary certification through AOBEM, AOBFP, AOBIM, or AOBPM
• Case documentation showing supervision of at least 500 treatments, distributed across the 13 treatment indications specified in the published requirements, based on institutional case frequency

That last item is often the long pole in the tent. Case logs accumulate over the course of fellowship training and early practice, and they need to reflect institutional case frequency across all 13 indications - not just the conditions your center happens to see most often. If you're still assembling this documentation, start now rather than waiting for a date to appear on the official page. For a full breakdown of every prerequisite, see our UHM Requirements 2026: Eligibility, Prerequisites & How to Qualify guide.

Fees and What They Actually Cover

The published fee for the initial written examination is $1,100. Recertification carries the same $1,100 fee. These figures are separate from any costs tied to your primary board certification (AOBEM, AOBFP, AOBIM, or AOBPM), your fellowship training, or AOA membership dues that may apply independently.

Budgeting for this exam means accounting for the examination fee itself, plus any time and travel costs associated with sitting for the administration once it's scheduled. For a complete cost picture that includes these line items together, see UHM Certification Cost 2026: Complete Pricing Breakdown.

Eligibility Checkpoints That Affect When You Can Sit

Eligibility for this AOA subspecialty certification requires all of the following before you can be approved to test:

• A COCA-accredited osteopathic medical degree
• A one-year AOA-approved internship
• A one-year AOA- or ACGME-approved hyperbaric medicine fellowship
• Primary certification through AOBEM, AOBFP, AOBIM, or AOBPM
• Unrestricted medical licensure and good ethical standing

If any of these pieces is still in progress - say, your fellowship completion or your primary board result - your actual test date will be pushed to whichever administration comes after you clear that gap. This is a key reason candidates should treat "exam dates" as a moving target tied to personal eligibility status rather than a fixed public calendar. Our eligibility and prerequisites guide walks through each checkpoint in more detail.

Building a Study Timeline Around an Unconfirmed Date

Not knowing the exact date doesn't mean you can't plan. Instead of counting down to a specific day, build a rolling preparation cycle keyed to your eligibility milestones, and treat the exam window as something that could open with a few months' notice. This approach keeps you ready whenever the committee confirms your administration.

For a structured, exam-specific preparation plan, our UHM Study Guide 2026 lays out how to sequence review material against this exact blueprint. And if you want to gauge whether your current knowledge is exam-ready, practicing with realistic multiple-choice items on our practice test platform is one of the fastest ways to find blind spots before the real administration.

Time Allocation by Domain Weight

The written examination's four-category outline is heavily front-loaded toward two domains. Understanding this weighting should directly shape how many hours you spend on each topic area.

The OCC Recertification Cycle

Once certified, maintaining your credential runs on a 10-year cycle through the AOA's Osteopathic Continuous Certification (OCC) pathway, which includes a written recertification assessment. The recertification fee matches the initial exam fee at $1,100.

Outside of that written assessment, the conjoint committee does not add a separate UHM-specific continuing education requirement on top of what your primary board already mandates. In practice, that means staying current on your primary-board CME and OCC compliance, plus keeping active, unrestricted licensure, covers the bulk of what's expected between exam cycles. This is a much lighter ongoing burden than many candidates assume going in - it's simply layered on top of obligations you already carry through your primary certification.

What to Do Right Now

Given that the official scheduling page shows outdated text, your best move in 2026 is a three-part approach:

1. Confirm the current administration date directly with the AOA certification office rather than relying on cached or outdated page content.
2. Close any documentation gaps now - fellowship verification, primary board certification, and case logs across all 13 treatment indications - since these determine how quickly you can be cleared once a date is confirmed.
3. Start content review on a rolling basis, weighted toward Fundamentals and Diving medicine, so you're exam-ready whenever your confirmed date arrives.
