The 2026 D. ABDSM Fee Schedule at a Glance
Earning the Diplomate of the American Board of Dental Sleep Medicine (D. ABDSM) designation is not a single-payment event. The cost has layers: prerequisite education, the examination fee itself, possible retake fees, and an ongoing maintenance obligation once you hold the credential. This guide breaks each layer down using the figures in the ABDSM Certification Program Guidelines and Policies, effective August 5, 2026, which is the governing document for fees and rules.
If you are still deciding whether the credential is right for you, pair this article with our ROI analysis of the D. ABDSM certification. If you want the full eligibility picture before spending anything, see D. ABDSM requirements and how to qualify.
| Cost Item | Amount (USD) | Who It Applies To |
|---|---|---|
| Exam fee, new applicant | 995 | First-time applicants and those reestablishing eligibility |
| Exam fee, standard retake | 395 | Eligible candidates retaking within their eligibility period |
| Exam fee, Federal Service | 250 | Qualifying full-time US/Canadian Federal Service dentists, including eligible retakes |
| Annual maintenance fee | 200 | Diplomates holding the credential |
| Annual maintenance fee, Federal Service | 50 | Qualifying Federal Service dentists with verified active-duty status |
Exam Fees: Who Pays $995, $395 or $250
The standard application fee: USD 995
This is the figure most candidates will pay. It applies to new applicants and also to anyone who is reestablishing eligibility after their original window closed. The fee covers the 150-question, three-hour proctored computer examination administered by Kryterion, which can be taken at a test center or remotely. The exam is offered twice yearly, so timing your application matters; our guide to D. ABDSM exam dates, windows and deadlines explains how to plan around the schedule.
The retake fee: USD 395
If you do not pass, you may retake the exam during your eligibility period. Up to two retakes are permitted, and each eligible standard retake is priced at USD 395. That is substantially less than the original fee, but it is still a real cost, and it does not include any additional preparation spending you decide to make after a first attempt.
The Federal Service rate: USD 250
The guidelines set USD 250 for qualifying full-time US/Canadian Federal Service dentists, and this rate extends to eligible retakes. Note a wrinkle: the application webpage describes the discount more narrowly as active-duty military. If you work in federal service but are not on active duty, confirm your category directly with ABDSM and read it against the dated guidelines before assuming you qualify.
Costs You Incur Before You Can Apply
The exam fee is not your first expense. Eligibility requires US/Canadian permanent residency, a DDS/DMD or equivalent degree, and either an active unrestricted US (including territories) or Canadian dental license, or a permitted restricted faculty license combined with full-time employment at an accredited US/Canadian dental school. Those are credentials you likely already hold, so they add no new cost. The real upfront investment is the AADSM Mastery Program (or an AADSM-accredited Mastery Program). Under the dated guidelines, you must complete it before applying. The older FAQ phrases this as completion before the exam, which is a looser reading, but planning to finish before you submit your application is the safe course. The tuition, travel and time away from your practice for that program are separate from ABDSM's fees, and you should price them from the program provider rather than from ABDSM.
Two cost-relevant points follow from this:
- Initial eligibility lasts three years after Mastery completion. The clock is a budgeting constraint, because a lapse triggers extra cost (covered below).
- ABDSM does not require case submissions. Unlike some specialty boards, you are not paying to compile, photograph and document cases for review, which removes a common hidden expense.

What a Retake or Lapse Costs You
The cost curve bends sharply depending on whether you stay inside your eligibility window.
Staying within eligibility
Inside the three-year window you may retake up to two times at USD 395 each. In the worst case within that window, you would pay the original USD 995 plus two retakes, a total of USD 1,785 in exam fees alone. That figure is simple arithmetic on published fees, not a prediction of how many attempts any candidate needs.
Reestablishing eligibility
If your eligibility expires or your retakes are exhausted, reestablishing it means paying the USD 995 new-applicant rate again, plus meeting an education requirement. You can satisfy that requirement in one of two ways:
- Complete the entire Mastery Program again, or
- Earn 65 additional qualifying CE hours from the preceding three years that have not previously been submitted.
The 65-hour route is usually the cheaper path in tuition terms, but only if you have been accumulating CE you have not already counted. This is the most expensive failure mode in the whole process, which is why preparing properly the first time pays for itself. Our difficulty guide and pass rate analysis explain what is and is not publicly known about outcomes; notably, no official pass rate was published in the sources we reviewed, and ABDSM does not release candidate scores or the passing threshold.
Key Takeaway
Treat the three-year eligibility window as a budget deadline. Letting it lapse converts a USD 395 retake into a USD 995 application plus either a repeat Mastery Program or 65 fresh CE hours.
Keeping the Credential: Maintenance Costs
Certification has a recurring price. Under the 2026 guidelines, maintenance requires:
- 25 qualifying CE hours every two years, including at least five hours in dental sleep medicine.
- Up to 20 qualifying sleep-medicine CME credits may count toward that total.
- A USD 200 annual administrative fee, reduced to USD 50 for qualifying Federal Service dentists with verified active-duty status.
The maintenance webpage notes the annual fee is waived in the year certification is awarded, which softens the first-year cost. Over a two-year cycle the standard fee totals USD 400 (USD 100 for qualifying active-duty Federal Service dentists), before counting the price of whatever CE courses you take to hit your 25 hours.
Category caps that affect your CE spending
The dated guidelines cap practice-management, billing and coding credit at six hours, and lecturing and authorship at six hours. Because these caps limit how much of your 25 hours can come from cheaper or more convenient categories, you will need clinical dental sleep medicine CE to fill the remainder. Plan your CE purchases around the five-hour dental sleep medicine minimum and the caps rather than discovering them at renewal.
When ABDSM's Own Pages Disagree
Several fee-adjacent details differ between ABDSM's dated policy document and its webpages. These are the ones that can change what you pay or when you must act:
| Topic | 2026 Guidelines (dated) | Webpage or FAQ |
|---|---|---|
| Reduced exam fee eligibility | Qualifying full-time US/Canadian Federal Service dentists | Described as active-duty military |
| Mastery Program timing | Complete before applying | FAQ says before the exam |
| Practice-management CE cap | Six hours | Five hours |
| Lecturing/authorship cap | Six hours | 50% limit |
| Results notification | ABDSM certification portal | Regular mail |
The practical rule: default to the guidelines effective August 5, 2026, and confirm any ambiguity with ABDSM before paying. A misread category can mean paying USD 995 when you qualified for USD 250, or applying before you are eligible.
Spending on Preparation Without Wasting Money
ABDSM's official preparation materials are the exam blueprint, the device-characterization nomenclature, and the required reading list. These are the free baseline and should anchor your plan. The reading list does not cover every possible examination topic, and third-party study guides and practice questions are not official ABDSM study materials, so any paid resource is a supplement you choose, not a requirement.
A cost-conscious plan puts money where the exam puts weight. Domains 1, 2, 4 and 10 each carry 13%, the largest published share, together accounting for 52% of a typical exam (weights are approximate and may vary). That is where paid review time yields the most return:
Domain 1: Sleep physiology, pathophysiology and SDB consequences (13%)
The scientific foundation under everything else on the exam.
- Mechanisms and comorbidities of sleep-disordered breathing
- Medical consequences you must be able to explain to patients and physicians
Domain 2: Sleep testing (13%)
Understanding testing well enough to manage diagnosed SDB patients.
- Interpreting results to inform appliance therapy decisions
Domain 4: History, examination and imaging (13%)
Candidacy, treatment planning, goals, expectations and informed consent.
- Record keeping and appropriate imaging
- Determining who is a candidate for therapeutic intervention
Domain 10: Side effects of oral appliance therapy (13%)
Anticipating and managing side effects with proper informed consent.
- Linking side-effect management to documented consent
Smaller domains still add up. Domain 5 (appliance selection, impression and fitting) is 12%, Domain 3 (evidence-based treatment alternatives) is 9%, Domains 6 and 8 are 8% each, Domain 9 (medical versus dental model) is 6%, and Domain 7 (long-term follow-up) is 5%. For a full walkthrough, read the exam domains guide and the D. ABDSM study guide; the one-page cheat sheet works well as a final review.
One scheduling idea tied to the weights
Front-load the 13% domains
- Spend your first blocks on Domains 1, 2, 4 and 10, since they carry the most weight
- Use the blueprint to check each objective against what you know
Appliance and calibration skills
- Cover Domains 5 and 6 together, since selection feeds directly into titration
Fill the remaining domains and practice
- Review Domains 3, 7, 8 and 9, then take timed 150-question practice sets on the practice test site
Because the exam is 150 questions in three hours, you have roughly 72 seconds per question, so practicing under timed conditions is a cheap way to avoid the USD 395 retake. Unauthorized notes, documents and electronic aids are prohibited in the exam, so your practice should mirror that closed-resource condition.
Building Your Total Budget
Here is a straightforward way to map the cost of the credential across its life, using only published fees:
| Phase | Standard Dentist | Qualifying Federal Service Dentist |
|---|---|---|
| Exam fee (first attempt) | USD 995 | USD 250 |
| Each standard retake | USD 395 | USD 250 (eligible retakes included) |
| Annual maintenance fee | USD 200 (waived in award year per webpage) | USD 50 with verified active-duty status |
| Prerequisite Mastery Program | Priced by program provider | Priced by program provider |
| CE for maintenance | 25 hours per two years, at your course costs | 25 hours per two years, at your course costs |
Two items in that table, Mastery Program tuition and ongoing CE, depend entirely on the providers you choose, so we have not put numbers on them. Quote them yourself and add them to the fixed ABDSM fees above.
Whether the total makes sense depends on how you plan to use the credential. Our earnings analysis and D. ABDSM jobs overview cover the career side, and the passing score article explains what ABDSM does and does not disclose about scoring. If you are newer to the credential itself, start with what D.

Frequently Asked Questions
The exam fee is USD 995 for new applicants or those reestablishing eligibility, USD 395 for an eligible standard retake, and USD 250 for qualifying full-time US/Canadian Federal Service dentists, including eligible retakes. These figures come from the Certification Program Guidelines effective August 5, 2026.
No. The AADSM Mastery Program, or an AADSM-accredited Mastery Program, is a separate prerequisite you must complete before applying. Its cost is set by the program provider, not by ABDSM.
Maintenance requires 25 qualifying CE hours every two years, including at least five in dental sleep medicine, plus a USD 200 annual administrative fee. Qualifying Federal Service dentists with verified active-duty status pay USD 50 annually, and the webpage notes the fee is waived in the year certification is awarded.
Up to two retakes are permitted during your eligibility period. If eligibility lapses or is exhausted, you reestablish it by paying the USD 995 application fee and either repeating the entire Mastery Program or completing 65 additional qualifying CE hours from the preceding three years that were not previously submitted.
No. ABDSM does not require case submissions, so you avoid the documentation and review costs that some other credentials impose. Your main costs are the Mastery Program, the exam fee, and ongoing maintenance.
