PA-COS Certification Cost 2026: Complete Pricing Breakdown

The Core Fee Structure: $350 and What It Covers

When people search for the cost of the PA-COS credential, they are really asking about the Certificate of Added Qualifications in Orthopaedic Surgery (CAQ-OS), awarded by the National Commission on Certification of Physician Assistants (NCCPA) and held alongside your PA-C. It is not a replacement for initial PA certification. If you need a refresher on the terminology, see our explainer on what PA-COS certification is.

The published fee for initial CAQ qualification is $350 in total, and it breaks into two parts:

That is the entire NCCPA charge for a first-time candidate who passes on the first attempt. There is no separate application surcharge in the facts NCCPA publishes for this credential, and the registration fee is paid once, not once per attempt.

Six Years, One Fee: How the Timeline Affects Spending

NCCPA allows six years to complete the initial requirements. That window matters financially because it shapes when you pay and how much slack you have if the first attempt does not go your way. The same six-year frame appears in the eligibility rules:

• 4,000 hours of specialty experience in the preceding six years
• 75 Category I specialty CME credits in six years, including 25 in the preceding two years
• A current PA-C and unrestricted licensure (all held licenses must be unrestricted)
• An attestation from a specialty physician, lead/senior PA, or physician/PA postgraduate program director, due within 90 days of your score report

Notice that the attestation requirement does not carry a separate NCCPA fee in the published material, but it does require coordination with a supervisor who knows your procedural and patient-case experience. Build that relationship early. For scheduling mechanics, see PA-COS exam dates, windows, and deadlines.

What a Second Attempt Costs

If you do not pass, another examination attempt within the six-year period costs $250. The $100 registration does not repeat. That makes the worst plausible NCCPA spend for two attempts $600 ($100 + $250 + $250), and each further attempt within the window adds another $250.

The arithmetic is simple, but the strategic point is not: the exam fee is modest compared with the opportunity cost of waiting. A failed attempt delays whatever credential-linked benefit you were pursuing. If you want to understand how demanding the test is before you pay, read how hard the PA-COS exam is, and for scoring thresholds see the passing score breakdown.

Costs the $350 Does Not Include

The NCCPA fee is the smallest line item for most candidates. These are the expenses that actually move your budget:

Specialty CME (75 Category I credits)

You need 75 specialty Category I CME credits within six years, with at least 25 in the last two. Many orthopaedic PAs accumulate these through conferences, institutional programs, and online courses they would take anyway. Your out-of-pocket cost depends entirely on whether your employer funds CME. Because the credits must be specialty-relevant, generic CME may not count toward the requirement.

Time away from work

The exam itself involves two hours of testing plus a 15-minute tutorial and a 15-minute break, so budget at least half a day including travel and check-in at the Pearson VUE center. Add any study days you plan to take.

Optional ACLS

ACLS is recommended but not mandatory for this CAQ. If your employer already requires it, it costs you nothing extra; if not, you can treat it as optional and skip that expense without affecting eligibility.

Licensure upkeep

You must hold unrestricted PA licensure in a US jurisdiction or territory (or unrestricted government practice privileges), and every license you hold must be unrestricted. Routine license renewal fees are an ongoing cost, but they are not specific to this credential.

Practice Exam and Prep Spending

NCCPA sells a separate practice examination for $50. It has 60 questions, a 60-minute timer, and 180 days of access. It is deliberately limited: it does not provide item-by-item explanations and it does not predict whether you will pass. That makes it useful as a format rehearsal rather than a diagnostic tool.

The free sample-question critiques published by NCCPA, by contrast, do include explanations, so they are the best no-cost starting point. A reasonable layering looks like this:

Note that the real exam has two 60-question, 60-minute blocks, and review is limited to the active block. The NCCPA practice exam mirrors exactly one such block, which is why it pairs well with explanation-rich question banks.

Ten-Year Validity and Maintenance Costs

The CAQ is valid for ten years. To keep it, you must maintain your PA-C and unrestricted licensure, earn 125 specialty Category I CME credits during the cycle, and pass a maintenance examination. This is where long-term cost planning matters more than the initial $350.

The maintenance-only online option is open-reference, with 120 questions, five minutes per question, and an approximately six-week completion window. That format is different from the proctored initial exam, so do not assume your initial-exam strategy transfers directly. NCCPA's published maintenance fee schedule is the authoritative source for what that pathway costs; check it before you plan, since this article's verified figures cover the initial qualification.

Building a Realistic Budget

Because the exam spans nine content domains with very uneven weighting, you can also budget your study spending more intelligently. Two domains, Fractures/Dislocations and Soft-Tissue Injuries and Disorders, carry 25% each; Joint Disorders carries 20%. Together they account for 70% of the exam. Prioritize paid resources that go deep there before spending on smaller domains. Our complete guide to all nine content areas maps the full blueprint.

The blueprint also classifies questions by overlapping task categories, not additional domains: Formulating Most Likely Diagnosis (25%), Treatment/Intervention (25%), History Taking and Performing Physical Examination (20%), and Ordering and Interpreting Diagnostic and Laboratory Studies (20%) dominate. In practice, that means you are paying for decision-making skill, not rote recall, so favor resources that train case-based reasoning.

Weighing the Cost Against the Value

At $350 for a first-time pass, the NCCPA fee is low relative to many professional credentials. The question for most orthopaedic PAs is whether the CAQ strengthens their position with employers, credentialing committees, and specialty practices. We examine that tradeoff in Is the PA-COS certification worth it?, and you can see how the credential relates to compensation in the PA-COS salary guide. We avoid quoting salary or ROI figures here because the verified facts for this credential cover fees and requirements, not earnings.

If you are still deciding whether to invest, estimate three numbers for yourself: your likely number of attempts (see what the pass-rate data shows), your out-of-pocket CME cost for the 75 required credits, and any employer reimbursement available. Many employers fund certification and CME for specialty PAs, so ask before you pay.
