- CVTS here means NCCPA's Certificate of Added Qualifications in Cardiovascular and Thoracic Surgery, used as PA-C, CAQ-CVTS.
- It supplements PA-C; it is not an initial PA certification or a physician surgical-board exam.
- The initial exam is 120 multiple-choice questions in two 60-question blocks, delivered at Pearson VUE.
- You need 4,000 specialty hours and 75 Category I CME credits, including 25 in the last two years.
What the Credential Actually Is
The Certificate of Added Qualifications in Cardiovascular and Thoracic Surgery is a specialty credential for physician assistants who already hold PA-C status. It is awarded by the National Commission on Certification of Physician Assistants (NCCPA) and is written as PA-C, CAQ-CVTS. The word "added" matters: the certificate sits on top of your general PA certification. It does not replace it, and it is not a separate route into the profession.
It is also not a physician credential. Surgeons earn their specialty certification through physician surgical boards, with their own training pathways and examinations. The CAQ is a PA-specific recognition that you have documented experience, continuing education, peer-attested competency, and examined knowledge in cardiovascular and thoracic surgical practice. If you are searching for a broader explanation of the acronym itself, our pages on what CVTS stands for and what CVTS certification is cover the naming in more detail.
Who Issues It and Who Tests It
NCCPA is the issuer and sets every rule: eligibility, exam content, scoring, and renewal. The initial examination is delivered at Pearson VUE test centers. NCCPA publishes the program details on its specialty certificates page, and its policy documents are the authority for anything that changes, including the May 2026 review of the CAQ program policies.
Because policies are revised, treat any third-party summary (including this one) as a map and NCCPA's documents as the territory. Our CVTS requirements guide walks through the eligibility paperwork step by step.
Eligibility: What You Must Have Before You Apply
This credential is gated by experience and continuing education, not just by an exam. Every item below must be satisfied for the award.
| Requirement | What NCCPA Expects |
|---|---|
| PA certification | Current PA-C status |
| Licensure | Unrestricted PA license in a U.S. jurisdiction, or unrestricted government-agency PA practice privileges; every license you hold must be unrestricted |
| Specialty experience | 4,000 hours of cardiovascular/thoracic surgical PA experience within six years before you attest that the experience requirement has been met |
| Specialty CME | 75 specialty-focused Category I CME credits within six years before exam application, with at least 25 in the preceding two years |
| Attestation | Signed competency attestation from a qualified collaborating physician or lead/senior PA |
ACLS and perioperative or critical-care CME are recommended, but they are not additional mandatory course requirements. The practical lesson is to plan your CME early. Because 25 of the 75 credits must fall in the last two years, candidates who front-load their education and then pause can find themselves short at the moment they want to apply.
The Competency Attestation
Many candidates assume a surgical specialty credential includes a hands-on practical test. This one does not. Instead, a collaborating physician or a lead/senior PA who works in the specialty and knows your practice must attest that you have the required procedural and patient-management knowledge. A physician or PA postgraduate program director may sign for a PA who is enrolled in, or has graduated from, that program.
NCCPA publishes a dedicated attestation form for the CVTS specialty, and the procedural expectations are laid out there. Timing is flexible: the attestation may be submitted before you sit for the exam or within 90 days after score notification. It is a competency attestation, not a separate timed practical examination.
Exam Format and Test-Day Rules
The initial exam consists of 120 multiple-choice questions delivered in two blocks of 60 questions, with 60 minutes per block. The two hours of testing time exclude a 15-minute tutorial and a 15-minute break, which is why the appointment allocation is 2.5 hours.
- Closed book: personal books, notes, and calculators are prohibited.
- No going back across blocks: once you complete a block, it cannot be reopened. Use your within-block review time wisely, and do not count on revisiting early items after the break.
- Pacing: 60 questions in 60 minutes averages about a minute per item, so clinical-vignette questions need disciplined reading.
These conditions apply to the initial exam. The online maintenance option used later in the cycle works differently (covered below), so do not carry those open-reference habits into your first attempt. For a realistic sense of the challenge, see how hard the CVTS exam is.
Inside the Content Blueprint
NCCPA's Content Blueprint for the Cardiovascular and Thoracic Surgery CAQ examination classifies the exam in two separate ways. Keep them distinct, because they describe the same questions from different angles.
Classification one: medical content categories
Domain 1: Cardiac (38%)
The largest category and the natural anchor of your preparation. Expect the physiology, diagnosis, operative considerations, and postoperative management that surround adult cardiac surgery.
- Coronary, valvular, and aortic disease as they present to a surgical team
- Interpreting the diagnostic data that drives operative decisions
- Perioperative and postoperative patient management
Domain 2: Thoracic (28%)
The second-largest category, covering the chest conditions managed surgically and the care pathways around them.
- Pulmonary, pleural, mediastinal, and esophageal conditions
- Preoperative evaluation and postoperative care for thoracic procedures
- Complications and their recognition
Domain 3: Vascular (10%)
A smaller slice, but one that rewards targeted review. Use the blueprint's 10% weight rather than older figures you may see elsewhere.
- Arterial and venous disease relevant to the surgical patient
- Diagnostic evaluation and treatment decisions
Domain 4: Critical Care (19%)
The third-largest category and the one that most reflects daily life on a cardiothoracic ICU or step-down unit.
- Hemodynamic management and organ-system support
- Ventilation, sedation, and postoperative physiologic monitoring
- Recognizing and responding to deterioration
Domain 5: Legal/Ethical Issues and Emerging Topics (5%)
Small in weight, easy to neglect, and therefore a source of avoidable misses.
- Professional, legal, and ethical aspects of surgical practice
- Newer developments in the field
The blueprint's illustrative subtopics are examples, not an exhaustive syllabus, and the five domain lines describe exam content categories rather than a preparation curriculum. Our complete guide to all five CVTS content areas goes deeper on each one.
Classification two: cross-cutting tasks
The same blueprint separately weights the kinds of clinical work a question asks you to perform. These percentages describe the same exam questions as the domains above; they are not eight more domains and should not be added to the medical-content distribution.
| Task Category | Weight |
|---|---|
| History and Physical | 10% |
| Ordering and Interpreting Diagnostic and Laboratory Studies | 20% |
| Formulating a Diagnosis | 15% |
| Health Maintenance | 5% |
| Clinical Intervention | 20% |
| Pharmacotherapy | 20% |
| Applying Scientific Concepts | 5% |
| Legal/Ethical Issues and Emerging Topics | 5% |
Read that table as a study signal. Diagnostic studies, clinical intervention, and pharmacotherapy together represent a large share of what you will be asked to do, so a candidate who knows anatomy cold but is shaky on perioperative drug management and test interpretation is exposed.
Key Takeaway
Study across both grids at once. When you review a Cardiac topic, ask which task it tests: interpreting a study, choosing an intervention, or selecting a drug. That habit maps your preparation onto how the exam is actually built.
Fees, Scoring Timeline, and Award
The initial fee totals USD $350: a $100 registration/administrative fee plus a $250 examination fee, per NCCPA's FAQs. Our CVTS certification cost breakdown covers related costs such as CME and the optional practice exam.
Passing the specialty exam is necessary but not sufficient. The award requires a passing result and completion of all non-exam requirements. NCCPA releases scores after validation, generally eight to ten weeks after administration, so do not plan around instant results. The initial CAQ process must be completed within six years after initiation.
A numeric passing threshold and an official specialty-specific pass rate were not verified for this article, and commercial pass-rate claims are not official statistics. If you want context on what is and is not known, read our pages on the CVTS passing score and the CVTS pass rate. For scheduling, see CVTS exam dates and deadlines.
Ten-Year Validity and Renewal
The certificate is valid for ten years, provided you maintain PA-C status 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 may make three maintenance-exam attempts during years nine and ten, and an earlier pass can reset the ten-year cycle. Maintenance can be taken at a test center or through a distinct online exam: 120 questions, five minutes per question, and roughly a six-week completion window. The online version permits printed or online references but requires independent work. Those are maintenance conditions, not initial-exam conditions.
Official Preparation Sources
Two NCCPA resources are directly relevant. First, the Sample Cardiovascular/Thoracic Surgery Questions & Critiques document (copyright 2021) shows question style and rationale. Second, NCCPA sells an optional $50 practice examination. NCCPA lists one practice form for this specialty, with a 180-day completion window; its feedback is educational and does not predict whether you will pass.
One caution: the 2021 sample-question annotations retain older weights, including Cardiac 40% and Vascular 5%. Use the content blueprint's Cardiac 38% and Vascular 10% when planning. Pair these official materials with the CVTS study guide and a quick-reference CVTS cheat sheet, and use realistic question practice on the CVTS Exam Prep practice test site to build timing under closed-book conditions.
Sequencing Your Study by Blueprint Weight
Because the exam is dominated by Cardiac, Thoracic, and Critical Care, a sensible order front-loads those areas and keeps the small domains alive with short, recurring touchpoints. This is one possible eight-week arrangement; adjust to your own experience.
Cardiac (38%)
- Work through disease states alongside diagnostic interpretation and drug management
- Tag each practice miss as a content gap or a task gap
Thoracic (28%)
- Pair preoperative evaluation with postoperative complication recognition
- Revisit Cardiac items briefly to keep them fresh
Critical Care (19%)
- Focus on hemodynamics, ventilation, and monitoring decisions
- Practice commit-and-move pacing within 60-minute blocks
Vascular (10%) and Legal/Ethical (5%)
- Short, targeted reviews of both smaller domains
- Confirm you are using the blueprint weights, not the older sample-critique weights
Integration
- Take the optional NCCPA practice exam as a diagnostic, not a prediction
- Simulate two 60-question blocks with a break and no references
Who Hires PAs With This Credential
PAs working in cardiovascular and thoracic surgery typically practice in settings such as hospital cardiac surgery programs, thoracic surgery services, cardiothoracic ICUs, and surgical teams that manage both the operating-room and postoperative phases. Roles often span first-assisting, rounding, perioperative management, and critical-care coverage, which is why the exam blends operative, thoracic, vascular, and ICU content.
Whether the credential changes your employment prospects or pay is a separate question, and this article does not assume a certification-caused pay premium. Hiring practices vary by institution, and many employers value documented experience first. For a measured look at the trade-offs, see whether the CVTS certification is worth it, the CVTS salary guide, and our overview of CVTS jobs. If you are still building specialty experience, CVTS training options are worth exploring.
Frequently Asked Questions
No. It is NCCPA's Certificate of Added Qualifications for PAs who already hold PA-C. It supplements your PA certification and is not a physician surgical-board examination.
