- The initial PAAI examination fee is $1,700; a retake costs $1,400.
- Cancel in writing at least 15 full days out to get a refund minus a $300 processing fee.
- OCC maintenance runs $250 per year via the AOA Learning Portal, not a large recurring exam fee.
- Certification terms are ten years for pre-2025 cohorts, but only two years for the 2025 cohort.
Cost Overview: What Certification Actually Costs
Candidates researching Certification in Adult & Pediatric Allergy & Immunology Subspecialty want a straight answer before they commit fellowship time and money to the process. The program is administered by the American Osteopathic Conjoint Examination Committee on Pediatric and Adult Allergy and Immunology, operating under the American Osteopathic Association (AOA), and is commonly referenced by its exam program name, PAAI. This article focuses specifically on the initial subspecialty certification examination, not the separate longitudinal Osteopathic Continuous Certification (OCC) assessment that diplomates complete after they're certified.
The headline number is simple: the initial examination costs $1,700. If you need to retake it, the retake fee drops to $1,400. There is no tiered "early bird" or "late" pricing structure published for this exam - the fee is the fee, regardless of when in the registration window you apply.
Fee Breakdown by Scenario
Because pricing questions usually come down to "which scenario applies to me," here's how the fees split out across the situations most candidates encounter.
| Scenario | Cost | Notes |
|---|---|---|
| First-time initial examination | $1,700 | Covers the full 250-question, four-section exam |
| Retake after a failed attempt | $1,400 | Lower than the initial fee; no limit specified beyond standard eligibility rules |
| Cancellation with 15+ days' notice | Refund minus $300 | Written cancellation required |
| Cancellation inside 15 days | No refund implied | Plan your schedule conservatively |
| Annual OCC maintenance (post-certification) | $250/year | Delivered through the AOA Learning Portal |
Notice that the retake fee is $300 less than the initial fee - a meaningful incentive to walk in prepared the first time. If you're unsure how ready you are, the Adult & Pediatric Allergy & Immunology Study Guide 2026 lays out a first-attempt preparation strategy built around the exam's actual content weighting, and our practice test platform can help you gauge readiness before you pay for a second attempt you might not need.
Cancellation and Refund Policy
The refund mechanics are straightforward but easy to miss if you're not reading the fine print. A written cancellation submitted at least 15 full days before your scheduled examination date qualifies for a refund of your fee, less a $300 processing fee. That means if you paid the full $1,700 initial fee and cancel in time, you'd receive $1,400 back - coincidentally the same number as the retake fee, though the two are unrelated policies.
Miss that 15-day window and you should assume the fee is not recoverable. Given that eligibility depends on verified completion of fellowship training and rotations, candidates who are cutting it close on training completion should build in extra buffer before locking in a registration date. If you're not yet sure whether you meet the eligibility bar, review the Adult & Pediatric Allergy & Immunology Requirements 2026 guide before you pay anything.
Key Takeaway
Don't register the moment you're eligible. Confirm your rotation completion status and personal readiness first - the $300 processing fee on cancellations is real money, and a late cancellation can cost you the full amount.
What Your Exam Fee Actually Covers
Unlike some certification exams that add facility fees, proctor fees, or software fees on top of the base price, the PAAI initial examination fee is inclusive of the delivery method. The exam is remote-proctored through MonitorEDU on the PARADIGM examination platform, meaning you take it from your own space rather than paying to travel to a test center.
What that $1,700 buys you, structurally:
- 250 multiple-choice questions split across four 90-minute sections (63, 62, 63, and 62 questions respectively)
- Scheduled breaks of 10, 30, and 10 minutes - 50 minutes of break time layered into a 6-hour, 50-minute total appointment
- Remote-proctoring software and identity verification through MonitorEDU
- On-screen resources provided during the exam: electronic lab values, a calculator, and a scratchpad
- Scoring on a 200-800 scaled system, with 500 required to pass
What you must supply yourself: a suitable computer, a smartphone with a working camera (used for remote proctoring setup), valid identification, and a private, quiet test space free of prohibited materials. There's no facility rental cost because there's no facility. For the mechanics of how scoring translates into a pass/fail decision, see the Adult & Pediatric Allergy & Immunology Passing Score 2026 breakdown.
Where Your Study Time - and Indirectly, Your Money - Should Concentrate
The exam blueprint weights content unevenly across eight domains, and that weighting should drive how you allocate prep resources (courses, question banks, review time) so you're not overspending effort on low-yield areas.
- Basic science - 30% (by far the largest single domain)
- Pulmonary diseases - 13%
- Allergic and non-allergic upper respiratory tract diseases - 13%
- Hypersensitivity reactions and mast cell disorders - 11%
- Primary and secondary immunodeficiencies - 10%
- GI disorders - 10%
- Skin disorders - 10%
- Autoimmunity and other immunological disorders - 3%
For the full breakdown of what each domain actually tests, see the Adult & Pediatric Allergy & Immunology Exam Domains 2026 guide.
Ongoing Costs: The OCC Program
Certification isn't a one-time transaction - it comes with a maintenance obligation, and understanding its cost structure matters when you're budgeting for the full lifecycle, not just the initial exam.
Once certified, diplomates enter the Osteopathic Continuous Certification (OCC) program. New diplomates don't start OCC immediately; it begins after one full calendar year of certification (for example, the 2025 cohort begins OCC in 2027). The OCC program includes:
- 16 untimed, open-resource PAAI questions completed annually
- A 70% annual passing criterion on those questions
- A $250 annual assessment fee, administered via the AOA Learning Portal starting with the 2026 cycle
- Continued licensure and primary-board CME compliance (no separate conjoint-subspecialty CME quota required)
- One quality-improvement activity every ten years
Compare that $250/year recurring cost against the one-time $1,700 initial fee, and the long-term maintenance burden is modest relative to the upfront investment. It's a meaningfully different cost profile than the initial exam and worth factoring into any multi-year financial planning around the credential.
Indirect Costs Candidates Overlook
The $1,700 exam fee is the visible number, but it's not the only cost tied to earning this credential. Before you can even register, eligibility requires:
- AOBIM or AOBP primary certification already in hand - a prerequisite credential with its own cost history
- An active, unrestricted medical license (ongoing licensing fees are separate and recurring)
- Completed and verified allergy/immunology fellowship training, or at least 80% of required clinical rotations for senior fellows sitting early
- Professional and ethical standing documentation
None of these carry a published fee tied to the PAAI exam itself, but they represent time and administrative overhead that candidates sometimes underestimate when budgeting for "the cost of certification." If your training timeline is tight, the Adult & Pediatric Allergy & Immunology Exam Dates 2026 guide can help you line up your rotation completion with a realistic registration window, avoiding a rushed registration you might later need to cancel - and pay $300 for the privilege.
Putting the Cost in Context
A $1,700 initial fee (or $1,400 on retake) is a meaningful expense, but it should be weighed against what the credential represents: subspecialty-level recognition in allergy and immunology built on top of AOBIM or AOBP primary certification. Employers and credentialing committees that specifically require or prefer this conjoint subspecialty certification are evaluating candidates who've cleared a 250-question exam covering basic science, immunodeficiencies, pulmonary and upper respiratory disease, hypersensitivity and mast cell disorders, GI, skin, and autoimmune content at a defined 500-scaled-score threshold.
Whether that translates into measurable career return depends on your practice setting, region, and employer expectations - a question worth exploring in more depth in Is the Adult & Pediatric Allergy & Immunology Certification Worth It? and in the Adult & Pediatric Allergy & Immunology Salary Guide 2026. If you're evaluating job market fit before you spend the exam fee, the Adult & Pediatric Allergy & Immunology Jobs overview is a useful companion read.
Budgeting Your Preparation Timeline
Because the retake fee ($1,400) is nearly as expensive as the initial fee ($1,700), the smartest financial move is spending on preparation resources upfront rather than risking a second sitting. A cost-aware prep timeline should weight study time the same way the exam weights content - heaviest on Basic science, then the mid-weight clinical domains, with lighter review passes on Autoimmunity given its 3% share.
Basic Science Foundation (30% of exam)
- Build the deepest review block here since it's nearly a third of all 250 questions
- Use timed question sets to mirror the four 90-minute sections
Pulmonary and Upper Respiratory Disease (13% + 13%)
- Pair these two domains since they overlap clinically
- Practice under the same break-timing structure (10/30/10 minutes) you'll face on exam day
Hypersensitivity, Mast Cell Disorders, Immunodeficiencies (11% + 10%)
- Run full-length practice sessions on our practice test platform to simulate the 6-hour-50-minute schedule
GI, Skin, and Autoimmunity (10% + 10% + 3%) + Full Review
- Lighter pass on lower-weighted content
- Final mixed-domain review using a one-page reference like the Adult & Pediatric Allergy & Immunology Cheat Sheet 2026
If you want a sense of how difficult candidates generally find the exam relative to this timeline, the How Hard Is the Adult & Pediatric Allergy & Immunology Exam? guide and the Adult & Pediatric Allergy & Immunology Pass Rate 2026 article are useful companions to this cost breakdown - both help you decide how much prep investment is proportionate to the $1,700 stake.
