- The 2026 ABAI initial certification exam fee is $2,650, with a $500 late application penalty.
- The exam window runs September 28-October 2, 2026, at Pearson VUE centers via DRC.
- Maintenance of Certification adds a recurring $400 annual fee plus CME and CAP obligations.
- Passing uses an absolute minimum standard, not a moving percentage cutoff, so budget for one focused attempt.
Cost Overview: What ABAI Actually Charges
Physicians researching Certification in Allergy & Immunology often start with the wrong number in mind because several unrelated credentials share the "Allergy & Immunology" name. This article covers exactly one credential: the initial physician certification examination administered by the American Board of Allergy and Immunology (ABAI). It is not the fellows' In-Training Examination, and it is not a Maintenance of Certification (MOC) assessment - those are separate, differently priced processes.
For candidates budgeting for 2026, the core figure is straightforward: the ABAI initial certification examination fee is $2,650. That single fee covers your seat at a Pearson VUE test center, coordinated through Data Recognition Corporation (DRC), for the 225-question, seven-hour, two-session exam. There is no separate registration fee layered on top for the standard application timeline.
2026 Fee Breakdown Line by Line
Unlike credentials that bundle multiple hidden charges, ABAI's initial certification pricing is relatively transparent. Here is how the numbers break down for the 2026 cycle:
| Item | 2026 Cost | Notes |
|---|---|---|
| Initial certification exam fee | $2,650 | Standard on-time application |
| Late application fee | +$500 | Added to the base fee if you miss the standard deadline |
| MOC annual fee | $400/year | Recurring after certification, part of the ten-year cycle |
| CAP annual questions | 80 questions/year (two blocks) | Open-resource, ten minutes per question |
Notice what is not on this list: there is no published domain-by-domain fee, no charge tied to the number of subdomains tested, and no separate fee structure for the Basic Science versus Clinical Science cross-cutting classification. The $2,650 fee is flat regardless of how your preparation time is distributed across Allergy and Hypersensitivity Principles and Disorders (54%), Immunological Disorders (45%), or Emerging Health Priorities (1%). For a full breakdown of how those weights translate into study priorities, see the Allergy & Immunology Exam Domains Guide.
Why the Fee Structure Matters for Study Planning
Because you pay one flat fee for the entire 225-question exam, there is no financial incentive to "skip" a lower-weighted domain. Emerging Health Priorities is only 1% of the blueprint, but a wasted attempt costs the full $2,650 again - so comprehensive coverage protects your investment more than narrow cramming.
- Immunodeficiencies is the single largest named subdomain at 16% of the whole exam - a disproportionately high-value area relative to its narrow scope.
- Food and Drug Allergy/Hypersensitivity Reactions is tested separately from eosinophilic gastrointestinal disease, which falls under the Eosinophilic and Gastrointestinal Disorders subdomain - a distinction that trips up candidates who conflate the two.
Late Application and Timing Penalties
The $500 late application fee is the single largest avoidable cost in the entire certification process. Because the 2026 exam window is fixed at September 28-October 2, and the exam is delivered only within that window via Pearson VUE/DRC test centers, there is no flexible rescheduling the way some computer-based exams offer year-round.
Practically, this means your cost planning has to start well before the testing window itself. Candidates who wait until late summer to confirm eligibility documentation - ABIM and/or ABP certification status, verification of 24 consecutive months of full-time qualifying fellowship training, and unrestricted medical licensure - risk missing the standard deadline and absorbing the $500 penalty on top of the $2,650 base fee. For a full eligibility checklist, review the Allergy & Immunology Requirements guide, and confirm exact deadlines on the Allergy & Immunology Exam Dates page.
Key Takeaway
Treat the standard application deadline as a hard financial cutoff. Submitting early is the cheapest "test prep" decision you can make - it saves $500 with zero study effort required.
Maintenance of Certification Costs After You Pass
Passing the initial exam is not the end of the financial relationship with ABAI. New certificates carry a ten-year term, but maintaining that certificate requires ongoing participation and fees that candidates should factor into their long-term career budgeting.
- $400 annual MOC fee - a recurring charge separate from the one-time initial exam fee.
- 25 relevant AMA PRA Category I CME credits required every year.
- Annual license attestation confirming valid, current, unrestricted licensure.
- A patient-safety module completed once every ten years.
- A practice-assessment/quality-improvement module completed once every five years.
- Continuous Assessment Program (CAP) participation, using 80 open-resource questions annually across two blocks, at ten minutes per question, with an aggregate 80% passing standard over a five-year cycle after the two lowest-scoring blocks are dropped.
These MOC mechanics are governed by separate renewal rules - they do not affect the initial exam's content, format, or passing standard. If you're still preparing for the initial exam itself, the Allergy & Immunology Passing Score guide explains how the absolute minimum standard works for that first assessment.
Hidden and Indirect Costs Candidates Forget
Beyond the fees ABAI charges directly, candidates preparing for the initial certification exam typically incur several indirect costs worth planning for:
- Travel and lodging to a Pearson VUE test center for the fixed September 28-October 2 window, since the exam is not offered on-demand or remotely.
- Study materials covering both the Basic Science (~25%) and Clinical Science (~75%) cross-cutting balance, plus content-specific resources for immunodeficiencies, hypersensitivity mechanisms, and eosinophilic disorders.
- Time away from clinical duties during a seven-hour, two-session testing day.
- Potential repeat-attempt costs if the initial pass does not occur, since the full $2,650 fee applies again to any retake.
None of these are published as fixed dollar amounts by ABAI, so avoid trusting any source that cites a specific "average prep cost" - treat indirect expenses as variables you control through preparation quality rather than fixed fees. A structured approach, like the one outlined in the Allergy & Immunology Study Guide, reduces the odds of paying the exam fee twice.
Is the Investment Worth It?
When physicians weigh the $2,650 exam fee plus the ongoing $400 annual MOC fee against career trajectory, the calculation typically hinges on how the credential is used. ABAI certification is the recognized standard credential referenced by employers, hospital credentialing committees, and payer panels when verifying an allergist/immunologist's qualifications. Because the certificate carries a ten-year term before renewal cycles restart, the effective annual cost of the initial fee is modest when spread across a decade of practice.

Cost-to-Content Ratio
Given the 225-question format spread across the three blueprint categories, the effective "cost per tested concept" is lower than it appears once you account for the ten-year validity period. Spending study hours proportional to blueprint weight - heaviest on Allergy and Hypersensitivity Principles and Disorders, then Immunological Disorders, with minimal time on Emerging Health Priorities - protects your fee investment better than even coverage.
Budgeting Timeline for Your Exam Year
Financial planning for the exam should run parallel to content planning. A simple way to align both is to map fee deadlines against your study calendar, using resources like the Allergy & Immunology Cheat Sheet for rapid review once your budget and schedule are locked in.

Frequently Asked Questions
The base exam fee is $2,650. If you miss the standard application deadline, a $500 late fee is added, bringing the total to $3,150. This does not include travel, study materials, or the recurring MOC fees that begin after you pass.
Yes. The $2,650 figure applies specifically to the initial physician certification exam. The fellows' In-Training Examination and Maintenance of Certification assessments are separate processes with their own requirements, including the $400 annual MOC fee and CAP participation.
No. The $2,650 fee is flat regardless of how the 225 questions are distributed across Allergy and Hypersensitivity Principles and Disorders, Immunological Disorders, and Emerging Health Priorities. There is no itemized per-domain pricing.
Because passing is determined against an absolute minimum standard rather than a percentage curve, ABAI does not publish a "close miss" discount. A retake requires paying the full $2,650 exam fee again for the next available testing window.
Plan for the $400 annual MOC fee, 25 CME credits per year, and periodic module requirements (patient-safety every ten years, practice-assessment/quality-improvement every five years), plus ongoing CAP participation with its 80 annual questions.
