- Eligibility requires 4,000 hours of CVTS surgical PA experience and 75 Category I CME credits, 25 of them in the last two years.
- The initial exam has 120 multiple-choice questions in two 60-minute blocks, closed book, at a Pearson VUE test center.
- Cardiac (38%), Thoracic (28%) and Critical Care (19%) make up most of the blueprint.
What a CVTS Actually Is
"CVTS" shows up in many contexts, so precision matters. On this site, a CVTS is the Certificate of Added Qualifications in Cardiovascular and Thoracic Surgery, a specialty credential for physician assistants. Those who earn it use the designation PA-C, CAQ-CVTS. It signals that a certified PA has documented experience, continuing education, peer-attested competency, and exam-verified knowledge in the care of cardiac, thoracic, vascular, and critical care surgical patients.
If you are searching for alternate phrasings of the same question, you may also land on pages such as What Is CVTS?, What Does CVTS Stand For?, or CVTS Meaning. This article takes the practical angle: what the credential is, who qualifies, what the exam looks like, and what you need to know to pass it.
Who Issues It and What It Is Not
The credential is issued by the National Commission on Certification of Physician Assistants (NCCPA), the same organization that grants the PA-C. The CAQ is an add-on. It supplements your PA-C rather than replacing it, and it cannot be held without the base certification. Two clarifications prevent common confusion:
- It is not an initial PA certification. You must already be a current PA-C before you can apply.
- It is not a physician surgical-board examination. It is a PA-specific specialty credential, developed and administered through NCCPA's specialty certificate program.
For a broader look at how the credential is positioned, see What Is CVTS Certification?, or return to the main practice test site to start working through questions.
The Eligibility Stack: Credentials, Hours, and CME
The CAQ-CVTS is gated by several layers of prerequisites. Candidates need all of them before the credential can be awarded:
- Current PA-C certification.
- An unrestricted PA license in a U.S. jurisdiction, or unrestricted government-agency PA practice privileges. Every license you hold must be unrestricted.
- 4,000 hours of cardiovascular/thoracic surgical PA experience within the six years before you attest that the experience requirement has been satisfied.
- 75 specialty-focused Category I CME credits within six years before exam application, including at least 25 within the preceding two years.
The initial CAQ process must be completed within six years after it is initiated, so plan your timeline rather than starting the paperwork casually. For the full prerequisite walkthrough, read CVTS Requirements 2026: Eligibility, Prerequisites & How to Qualify.
The Competency Attestation
Unlike many certifications, the CAQ-CVTS includes a non-exam requirement: a signed attestation of procedural and patient-management knowledge. Understanding it early saves delays.
- Who signs: a collaborating physician, or a lead or senior PA, who works in the specialty and knows your practice. A physician or PA postgraduate program director may sign for a PA who is enrolled in or has graduated from that program.
- What they attest to: the required procedural and patient-management knowledge, using NCCPA's CVTS attestation form.
- When: attestation may precede the exam or arrive within 90 days after score notification.
- What it is not: a competency attestation, not a separate timed practical exam. Nobody watches you perform a procedure on test day.
A passing exam result alone does not earn the credential. A passing specialty-exam result and all non-exam requirements are necessary for the award. Candidates who pass and then discover their attestation is outstanding are the ones who feel this rule most painfully.
Exam Format and Test-Day Mechanics
| Feature | Initial CAQ-CVTS Exam |
|---|---|
| Questions | 120 multiple-choice |
| Structure | Two 60-question blocks, 60 minutes each |
| Appointment length | 2.5 hours (two hours of testing plus a 15-minute tutorial and 15-minute break) |
| Testing provider | Pearson VUE test centers |
| Resources | Closed book; personal books, notes, and calculators prohibited |
| Block rules | A completed block cannot be reopened |
The no-reopen rule changes how you should pace. Within a block you can navigate, but once you submit the first 60 questions, those answers are final. Use your 60 minutes per block deliberately: roughly one minute per question leaves little slack, so decide on a rule for flagging and moving on, and apply it consistently. Official logistics are in NCCPA's "What to Expect on Test Day" document.
Because the exam is closed book with no calculator, expect to recall thresholds, drug classes, and physiologic relationships from memory rather than compute them. For a realistic view of difficulty, see How Hard Is the CVTS Exam?
Content Map: Domains and Cross-Cutting Tasks
NCCPA's content blueprint classifies the same exam in two different ways. This is the single most misunderstood feature of the credential, so read carefully.
Medical content categories
| Domain | Weight |
|---|---|
| Cardiac | 38% |
| Thoracic | 28% |
| Vascular | 10% |
| Critical Care | 19% |
| Legal/Ethical Issues and Emerging Topics | 5% |
Cross-cutting task categories
Separately, the blueprint weights the kind of clinical task each question asks you to perform: 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%); and Legal/Ethical Issues and Emerging Topics (5%).
The blueprint's subtopics are illustrative, not exhaustive, and the domain lines describe exam content rather than a prescribed curriculum. One caution: NCCPA's 2021 sample-question critiques carry older annotations (for example Cardiac 40% and Vascular 5%). Use the blueprint's current figures of Cardiac 38% and Vascular 10%. For a domain-by-domain breakdown, see CVTS Exam Domains 2026: Complete Guide to All 5 Content Areas.
What Candidates Must Master in Each Domain
Cardiac (38%)
The largest category, and the one most candidates with adult cardiac surgery experience will find familiar. Expect questions that move from preoperative evaluation through intraoperative concepts to postoperative management.
- Coronary artery disease and revascularization decision-making
- Valvular disease: evaluation, timing of intervention, and postoperative issues
- Postoperative arrhythmias, pacing, and hemodynamic instability
- Anticoagulation and antiplatelet strategy around cardiac surgery
Thoracic (28%)
Second in weight, and often the weaker area for PAs who work primarily in adult cardiac programs. Do not under-prepare it.
- Pulmonary, pleural, and mediastinal disease relevant to surgical management
- Preoperative pulmonary risk assessment and postoperative complications
- Chest tube management and air leak evaluation
- Esophageal and airway conditions encountered in thoracic practice
Vascular (10%)
A smaller slice, but a meaningful one given the blueprint's weighting.
- Aortic and peripheral arterial disease presentation and evaluation
- Recognition of acute limb and visceral ischemia
- Perioperative vascular complications
Critical Care (19%)
The postoperative ICU is where cardiothoracic PAs spend much of their time, and the exam reflects it.
- Ventilator management, weaning, and respiratory failure
- Shock states, vasoactive and inotropic support, and mechanical circulatory support concepts
- Acute kidney injury, electrolyte disturbance, and fluid management
- Bleeding, coagulopathy, and transfusion decisions
Legal/Ethical Issues and Emerging Topics (5%)
Small, but it shares its name with a cross-cutting task weighting and is easy points for a prepared candidate.
- Informed consent, scope of practice, and documentation
- Professional responsibility in team-based surgical care
- Newer techniques and technologies entering the specialty
These bullets are illustrative of the kind of material the blueprint points toward, not a complete syllabus. For a structured approach, the CVTS Study Guide 2026 and the CVTS Cheat Sheet both help organize review.
Fees, Scoring Release, and Validity
The initial examination costs $350 total: a $100 registration/administrative fee plus a $250 examination fee. That figure covers the initial exam only and does not include travel, study materials, or the cost of earning your CME credits. A fuller breakdown is in CVTS Certification Cost 2026.
- Score release: NCCPA releases scores after validation, generally eight to ten weeks after administration. Plan around that gap, particularly if your attestation is still pending.
- Passing standard: NCCPA has not published a numeric passing threshold or a specialty-specific pass rate that we can verify, and commercial pass guarantees are not credible substitutes. See CVTS Passing Score and CVTS Pass Rate for what is and is not known.
- Validity: ten years, conditional on maintaining your PA-C and licensure.
Maintaining the credential
Renewal requires 125 specialty Category I CME credits earned during the cycle and submitted by the time you apply for the renewal exam, plus passing the specialty examination. Current policy allows three maintenance-exam attempts during years nine and ten. Maintenance can be taken at a test center or through a distinct online exam: 120 questions, five minutes per question, over roughly a six-week window. The online format permits printed and online references but requires independent work. Those conditions apply to maintenance only, not to the initial exam.
Official Prep Sources and a Domain-Weighted Plan
Start with what NCCPA itself provides. The Content Blueprint is a short, undated, three-page document, and the file's location is not evidence of an exam-version year. The Sample Cardiovascular/Thoracic Surgery Questions & Critiques (2021) show the question style, bearing in mind the outdated weight annotations noted above. NCCPA also sells an optional $50 practice examination: one form for this specialty, a 180-day completion window, and educational feedback that does not predict whether you will pass.
Weight your calendar to the blueprint rather than to your comfort zone. A sensible sequencing, tied to CVTS specifics:
Thoracic first
- Weighted at 28% and commonly the least familiar for cardiac-heavy PAs
- Pair it with the Vascular material so your weakest areas get the longest runway
Cardiac
- The 38% category deserves the most total hours
- Reinforce with Pharmacotherapy, since drug questions run through every domain
Critical Care and Legal/Ethical
- ICU physiology and ventilator logic at 19%
- Quick wins in the 5% Legal/Ethical category
Integration
- Timed 60-question blocks to rehearse the two-block format
- Review missed items by task type: diagnostics, intervention, pharmacotherapy
Adjust the length to your own timeline; the ordering logic is what matters. For timing considerations, see CVTS Exam Dates.
Who Hires CAQ-CVTS Physician Assistants
The credential is relevant wherever PAs support surgical patients with heart, lung, and vascular disease. Typical settings include:
- Academic medical centers with cardiac surgery, thoracic surgery, and transplant programs
- Community and regional hospitals with cardiac surgery and cardiovascular ICU services
- Private cardiothoracic and vascular surgical groups
- Federal and government facilities, which the eligibility rules explicitly contemplate through government-agency practice privileges
Roles span operating room first assistance, inpatient rounding, ICU management, clinic follow-up, and, in some programs, vein or conduit harvesting and procedural work. Whether the CAQ raises your pay or improves your hiring odds depends on the employer and market, and a pay premium should not be assumed. Look at CVTS Jobs, CVTS Salary Guide, and Is the CVTS Certification Worth It? before deciding. If you want hands-on practice questions, the main practice test is the place to begin.
