- The CAQ-CVTS is an NCCPA credential for certified PAs, added on top of PA-C, not a standalone certification.
- You need 4,000 hours of cardiovascular/thoracic surgical PA experience within six years before attesting that the requirement is met.
- 75 specialty Category I CME credits are required, with at least 25 earned in the preceding two years.
- A collaborating physician or lead/senior PA must attest to your procedural and patient-management knowledge.
What the CAQ-CVTS Actually Is
Before looking at eligibility, it helps to be precise about what you are qualifying for. The Certificate of Added Qualifications in Cardiovascular and Thoracic Surgery is issued by the National Commission on Certification of Physician Assistants (NCCPA) and is used as PA-C, CAQ-CVTS. It supplements your existing PA-C credential. It is not a separate initial PA certification, and it is not a physician surgical-board examination. If you have seen the abbreviation "CVTS" attached to other credentials elsewhere, set those aside: everything on this page concerns the NCCPA specialty certificate for physician assistants working in cardiothoracic surgery.
That framing shapes every requirement. NCCPA is not testing whether you can become a PA; it already certified that. It is asking whether you have enough sustained, documented experience in cardiovascular and thoracic surgery, enough specialty-focused education, and enough verified competence to carry a formal specialty designation. If you want the broader picture first, our overview of what CVTS certification is covers the basics, and this article focuses squarely on how to qualify.
The Requirements at a Glance
The requirements fall into four buckets: credential and licensure status, practice experience, continuing education, and a competency attestation. Then there is the exam itself. The table below summarizes the structure before we examine each piece.
| Requirement | What NCCPA Expects | Timing Rule |
|---|---|---|
| PA-C status | Current NCCPA certification | Must remain current |
| Licensure | Unrestricted PA license in a U.S. jurisdiction, or unrestricted government-agency PA practice privileges | Every license you hold must be unrestricted |
| Experience | 4,000 hours of cardiovascular/thoracic surgical PA experience | Within six years before attesting the requirement has been satisfied |
| CME | 75 specialty-focused Category I credits | Within six years before exam application, with at least 25 in the preceding two years |
| Attestation | Collaborating physician or lead/senior PA confirms procedural and patient-management knowledge | Before the exam, or within 90 days after score notification |
| Exam | 120 multiple-choice questions at a Pearson VUE test center | Whole process completed within six years of initiation |
A passing exam result alone does not earn the certificate. NCCPA requires a passing specialty-exam result and satisfaction of all non-exam requirements before the award is made. Candidates sometimes treat the attestation or hours documentation as an afterthought; it is not.
Active PA-C and Unrestricted Licensure
The foundation is a current PA-C. If your core certification has lapsed, there is no path to the specialty certificate until it is restored. Because the CAQ supplements PA-C, the validity of the added credential is also conditional on maintaining PA-C and licensure for as long as you hold it.
The licensure language deserves a careful read. You need either an unrestricted PA license in a U.S. jurisdiction or unrestricted government-agency PA practice privileges, and the standard applies to every license you hold. That means a restriction on a secondary-state license, even one you rarely use, can be a problem. Federal-service PAs, for example, may practice under government-agency privileges rather than a state license, and that route is explicitly recognized as long as the privileges are unrestricted.
The 4,000-Hour Experience Requirement
The experience requirement is the one that most often determines when a PA becomes eligible. NCCPA asks for 4,000 hours of cardiovascular and thoracic surgical PA experience, accumulated within the six years before you attest that the requirement has been satisfied. The hours must be PA experience in the specialty, which points to work in settings such as operating rooms, cardiothoracic ICUs, surgical floors, and the perioperative pathways that surround cardiac, thoracic, and vascular cases.
Thinking About What Counts
The exact accounting rules for specific duties live in NCCPA's policy documents, so read the Policies and Procedures for CAQ Non-Exam Requirements before you assume a role or rotation qualifies. As a practical matter, you should be able to describe your hours in terms of the clinical territory the exam itself draws on: cardiac surgery, thoracic surgery, vascular surgery, and the critical care of those patients. A PA whose day is split between a general surgery service and a heart program should document carefully rather than estimate generously.
Why the Six-Year Window Matters
Because hours must fall within six years of your attestation, an early-career PA cannot simply pile up years of experience and cash them all in later. Experience that ages out of the window no longer counts. Keep a running record of employers, dates, and approximate hours from your first day in the specialty, so you are never reconstructing it from memory.
The 75 Category I CME Credits
You must hold 75 specialty-focused Category I CME credits earned within six years before your exam application, and at least 25 of those must fall within the preceding two years. The two-year floor is the part that catches people. A PA who front-loaded education years ago may have plenty of total credits but too few recent ones.
"Specialty-focused" is the operative phrase: general CME that has nothing to do with cardiovascular or thoracic surgery does not do the job. Credits drawn from cardiac surgery conferences, thoracic and vascular surgical education, and critical care relevant to those patients are the natural fit.
Recommended, Not Required
NCCPA recommends, but does not mandate, additional preparation that many CVTS PAs already hold.
- ACLS is a recommendation, not an extra required course.
- Relevant perioperative and critical-care CME is encouraged, though only the 75 specialty-focused credits are the formal CME requirement.
- Do not let a recommended item delay your application if you meet every mandatory requirement.
The Competency Attestation
This is the requirement that surprises candidates who expect a hands-on practical test. There is no separate timed practical exam. Instead, a qualified person attests, in writing, to your required procedural and patient-management knowledge, using NCCPA's CVTS attestation form (Attestation of Knowledge and Skills of a Board Certified PA, CVTS).
Who Can Sign
- A collaborating physician who works in the specialty and knows your practice.
- A lead or senior PA who works in the specialty and knows your practice.
- A physician or PA postgraduate program director, for a PA who is enrolled in or has graduated from that program.
The signer must actually know your clinical work. Asking a respected surgeon who has never watched you manage a post-bypass patient is a weaker plan than asking the physician or senior PA who has seen your judgment daily.
When the Attestation Is Due
The attestation may be completed before you sit for the exam, or it may arrive within 90 days after score notification. That flexibility is useful, but do not treat it as permission to postpone. A late attestation can hold up an award you have already earned on the exam.
Key Takeaway
Line up your attesting physician or senior PA before you register. Share the CVTS attestation form early so there is no scramble inside the 90-day post-score window.
Fees and Exam Format
The initial exam costs $350 in total: a $100 registration/administrative fee and a $250 examination fee. For a fuller look at what else you may spend on preparation, see our breakdown of CVTS certification cost.
The exam is delivered at Pearson VUE test centers and consists of 120 multiple-choice questions in two 60-question blocks, with 60 minutes allotted per block. Two hours of testing time excludes a 15-minute tutorial and a 15-minute break, which is why the appointment allocation is about 2.5 hours. The exam is closed book: personal books, notes, and calculators are prohibited, and once you finish a block you cannot reopen it. That last rule has a real strategic consequence, because you cannot return to a flagged item in block one after moving to block two.
NCCPA releases scores after validation, generally eight to ten weeks after administration. NCCPA has not published a verified numeric passing threshold or an official specialty-specific pass rate that we can cite, so be cautious with any site that quotes one; our discussion of the CVTS pass rate and the CVTS passing score explains what is and is not verifiable.
What the Exam Covers
Qualifying is only the first gate; the exam content is the second. NCCPA's content blueprint organizes the exam two ways, and it is important not to confuse them. The five medical content categories are:
| Domain | Weight |
|---|---|
| Domain 1: Cardiac | 38% |
| Domain 2: Thoracic | 28% |
| Domain 3: Vascular | 10% |
| Domain 4: Critical Care | 19% |
| Domain 5: Legal/Ethical Issues and Emerging Topics | 5% |
Separately, the same blueprint weights cross-cutting tasks: Ordering and Interpreting Diagnostic and Laboratory Studies (20%), Clinical Intervention (20%), Pharmacotherapy (20%), Formulating a Diagnosis (15%), History and Physical (10%), Health Maintenance (5%), Applying Scientific Concepts (5%), and Legal/Ethical Issues and Emerging Topics (5%). These tasks are a second classification of the same exam, not eight extra domains and not additional percentages to stack on the medical-content distribution.
Cardiac, Thoracic, and Critical Care together account for the large majority of the medical content, which fits the profile of the PA who qualifies: someone managing operative patients and the intensive postoperative period around them. For a deeper look at each area, read our guide to all five CVTS exam domains.
Planning Your Qualification Timeline
Three clocks run at once: the six-year experience window, the six-year CME window with its two-year recency floor, and the six-year limit on completing the whole initial process once you initiate it. Treat them as separate deadlines, because satisfying one does not satisfy the others. The sequence below shows one sensible way to organize the work, keyed to the specific requirements rather than generic study habits.
Audit and document
- Total your cardiovascular/thoracic surgical hours and confirm they sit inside the six-year window.
- Verify every license is unrestricted.
- Tally specialty-focused Category I CME and check the 25-credit recency floor.
Secure the attestation and register
- Identify your attesting collaborating physician or lead/senior PA and share the CVTS form.
- Pay the $350 and schedule at Pearson VUE.
Prepare weighted by domain
- Spend the most time on Cardiac (38%) and Thoracic (28%).
- Give Critical Care (19%) dedicated blocks, since it overlaps every operative topic.
- Use NCCPA's sample questions with critiques and the optional $50 practice exam.
On preparation, NCCPA's optional $50 practice examination offers one practice form for this specialty with a 180-day completion window; it provides educational feedback and does not predict whether you will pass. Pair it with the official sample questions, remembering the weight discrepancy noted above. Our CVTS study guide lays out how to structure the preparation phase, and the CVTS exam dates article covers scheduling mechanics.
After You Pass: Validity and Renewal
Once awarded, the certificate is valid for ten years, conditional on maintaining PA-C and licensure. Renewal requires 125 specialty Category I CME credits earned during the cycle and submitted by the renewal-exam application, plus passing the specialty examination.
Under the May 2026 governing policy, you have three maintenance-exam attempts during years nine and ten, and an earlier pass can reset the ten-year cycle. Maintenance may use a test center or a distinct online examination: 120 questions, five minutes per question, and a roughly six-week completion window. The online format permits printed and online references but requires independent work. Those conditions apply to maintenance only; they are not initial-exam conditions, so do not plan to bring references to Pearson VUE.
Whether the credential justifies the effort depends on your own situation; we do not assume a certification-caused pay premium. If you are weighing that question, our analyses of the CVTS certification's value and the CVTS salary guide discuss the tradeoffs without inflating the numbers. You can also test your readiness with our CVTS practice tests as you approach your exam date.
Frequently Asked Questions
Yes. The certificate supplements your PA-C credential, so you must hold current NCCPA certification and an unrestricted PA license (or unrestricted government-agency practice privileges), with every license you hold unrestricted.
You need 4,000 hours of cardiovascular and thoracic surgical PA experience within the six years before you attest that the experience requirement has been satisfied. Hours that fall outside that window do not count toward it.
No. The procedural and patient-management requirement is met through a written competency attestation from a collaborating physician, a lead or senior PA in the specialty, or a qualifying postgraduate program director. It is not a separate timed practical exam.
Yes. The attestation may precede the exam or arrive within 90 days after score notification. Both the passing exam result and all non-exam requirements must be in place before NCCPA awards the certificate.
The initial CAQ process must be completed within six years after you initiate it. Separately, the experience and CME requirements each carry their own six-year lookback windows, so track all three timelines.
