- CVTS here means Certificate of Added Qualifications in Cardiovascular and Thoracic Surgery, written CAQ-CVTS and held alongside PA-C.
- NCCPA issues the credential; it supplements PA-C and is not a physician surgical-board exam.
- Eligibility requires 4,000 specialty surgical hours and 75 Category I CME credits, both within six years.
- The initial exam is 120 questions in two 60-question blocks, with a $350 total fee.
The Short Answer: What the Letters Spell Out
On this site, CVTS stands for Certificate of Added Qualifications in Cardiovascular and Thoracic Surgery. The four letters compress the specialty name: CardioVascular and Thoracic Surgery. Credentialed clinicians write it as PA-C, CAQ-CVTS, which tells a reader two things at once: the person is a certified physician assistant, and they have earned an added qualification in this surgical specialty.
The word "added" matters. A CAQ is not an entry-level certification and it does not replace anything. It sits on top of the PA-C credential and signals that a physician assistant has documented specialty experience, specialty continuing education, and a passing exam result in cardiovascular and thoracic surgery. If you are looking for the broader overview, the site also covers the topic in What Is CVTS? and CVTS Meaning; this article focuses on unpacking the name itself and what each part of it commits you to.
Who Issues the Credential and What It Is Not
The credential is issued by the National Commission on Certification of Physician Assistants (NCCPA), the same organization that certifies PAs. NCCPA lists the program under its specialty certificates, and the initial exam is delivered at Pearson VUE test centers.
Understanding what the name does not mean prevents most of the confusion candidates run into:
- It is not a separate initial PA certification. You must already hold a current PA-C to pursue it.
- It is not a physician surgical-board examination. It is a PA specialty credential with its own eligibility rules and content blueprint.
- It is not a practical or operative exam. The procedural side is handled through a competency attestation signed by a qualified colleague, not a timed hands-on test.
- It is not a license. State licensure and practice authority are separate from the certificate.
Why the Acronym Causes Confusion
"CVTS" is a common abbreviation in cardiothoracic surgery generally. Hospital departments, divisions, and job postings use it informally to describe cardiovascular and thoracic surgery as a service line, and other credentials and programs may borrow the same four letters. That informal use is the reason search results for the acronym can mix very different topics.
For a physician assistant, the practical filter is simple: if the credential is issued by NCCPA, requires PA-C, and is written CAQ-CVTS, it is the one covered here. Anything describing a different certifying body, a different fee schedule, or a physician-level surgical board belongs to a different credential and should not be used to plan your preparation. For a plain-language companion piece, see What Does CVTS Mean? and What Is CVTS Certification?.
How the Name Maps to the Exam Content
The title "Cardiovascular and Thoracic Surgery" is reflected directly in how NCCPA organizes exam content. The blueprint classifies questions into five medical content categories, and the weights below come from the official content blueprint.
| Part of the Name | Blueprint Domain | Weight |
|---|---|---|
| Cardio- | Cardiac | 38% |
| Thoracic | Thoracic | 28% |
| -vascular | Vascular | 10% |
| Surgery (perioperative and ICU course) | Critical Care | 19% |
| Professional practice | Legal/Ethical Issues and Emerging Topics | 5% |
Cardiac is the largest single category, so the first half of the acronym carries the most weight on the exam. Thoracic is the second-largest, and Critical Care is a substantial third because the postoperative period is such a large part of surgical PA work. Vascular is smaller at 10% but still meaningful. For a full walk-through of what each area covers, read CVTS Exam Domains: Complete Guide to All 5 Content Areas.
A Second Classification: Tasks
The same blueprint also weights cross-cutting tasks. These are a second way of slicing the same exam, not extra domains and not additional percentages to add on top of the medical categories.
- 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%
In practice, any given question sits in one medical category and tests one task. A question about a postoperative patient, for example, might be a Critical Care item that tests Pharmacotherapy. The blueprint's illustrative subtopics are examples, not an exhaustive list, so treat the document as a map of emphasis rather than a complete syllabus.
Who Qualifies to Sit for It
The "added" in Certificate of Added Qualifications is earned through documented experience, not just exam performance. The requirements are detailed in CVTS Requirements: Eligibility, Prerequisites & How to Qualify, but the core elements are:
- Current PA-C certification.
- Unrestricted licensure: an unrestricted PA license in a U.S. jurisdiction, or unrestricted government-agency PA practice privileges, with every license you hold unrestricted.
- 4,000 hours of cardiovascular and thoracic surgical PA experience within the six years before you attest that the experience requirement is satisfied.
- 75 specialty-focused Category I CME credits within six years before the exam application, including at least 25 within the preceding two years.
- A competency attestation from a collaborating physician or a lead/senior PA who works in the specialty and knows your practice. A program director may sign for a PA who is enrolled in, or graduated from, that program.
The attestation covers required procedural and patient-management knowledge. It may be submitted before the exam or within 90 days after score notification. Because this is a signed competency attestation rather than a timed practical, it is worth lining up your attesting colleague early. ACLS and perioperative or critical-care CME are recommended but are not additional mandatory course requirements. The overall initial process must be completed within six years after you begin it.
Key Takeaway
Passing the exam alone does not earn the certificate. NCCPA requires a passing specialty-exam result and completion of all non-exam requirements, so track your hours, CME, and attestation as carefully as your study schedule.
Exam Format, Fees, and Test-Day Mechanics
The initial examination has a fixed structure that candidates should know before they register. The financial side is covered in CVTS Certification Cost: Complete Pricing Breakdown, and timing details are in CVTS Exam Dates: Testing Windows, Deadlines & Scheduling.
| Item | Detail |
|---|---|
| Question count | 120 multiple-choice questions |
| Structure | Two blocks of 60 questions |
| Time per block | 60 minutes |
| Appointment length | About 2.5 hours, including a 15-minute tutorial and a 15-minute break |
| Total initial fee | $350 ($100 registration/administrative fee plus $250 examination fee) |
| Delivery | Pearson VUE test centers |
| Resources | Closed book; personal books, notes, and calculators prohibited |
Two mechanics deserve attention. First, the exam is closed book, so you cannot bring references or a calculator. Second, a completed block cannot be reopened, which means you need to finish your review of each 60-question block before you submit it. Scores are released after validation, generally eight to ten weeks after administration.
A numeric passing threshold and an official specialty-specific pass rate have not been verified, so be cautious with any site that quotes one. The topic is addressed with appropriate caution in CVTS Passing Score: Exactly What You Need to Pass and CVTS Pass Rate: What the Data Shows.
What the Credential Looks Like After You Pass
The certificate is valid for ten years, conditional on maintaining your PA-C and licensure. Maintenance has its own rules, and they differ from the initial exam in useful ways:
- CME: 125 specialty Category I CME credits earned during the cycle and submitted by the renewal-exam application.
- Exam: You must pass the specialty examination again. Current policy allows three maintenance-exam attempts during years nine and ten.
- Delivery options: Maintenance may use a test center or a distinct online exam with 120 questions, five minutes per question, and an approximately six-week completion window. The online version permits printed or online references but requires independent work. Those open-reference conditions do not apply to the initial exam.
Where the Credential Matters in Hiring
The CAQ-CVTS is most relevant to PAs working in surgical and perioperative settings centered on the heart, lungs, chest, and vasculature. Typical environments include:
- Hospital cardiac surgery programs, including operating room first-assist roles and inpatient surgical service coverage
- Thoracic surgery services handling pulmonary, esophageal, and mediastinal cases
- Cardiovascular and surgical intensive care units
- Vascular surgery practices and combined cardiovascular surgery groups
- Academic medical centers with surgical residency or fellowship programs
Employers may view the credential as evidence of specialty commitment and verified experience, but outcomes vary by employer, region, and role. Whether it changes your compensation or opens specific doors is a separate question that depends on your situation, and no pay premium should be assumed.

Preparing With the Name in Mind
Because the credential's name maps so directly onto the blueprint, the most efficient preparation mirrors the weights. Use NCCPA's own materials first: the Content Blueprint, the Sample Cardiovascular/Thoracic Surgery Questions & Critiques, and the optional $50 practice exam. NCCPA lists one practice form for this specialty with a 180-day completion window; its feedback is educational and does not predict an exam pass.
Cardiac First
- Spend the largest block here: 38% of content
- Pair each topic with the tasks that dominate the exam: diagnostic interpretation and pharmacotherapy
Thoracic and Vascular
- Thoracic carries 28%, so it earns more time than its smaller neighbor
- Vascular is 10% on the current blueprint, double what the older sample annotations suggest
Critical Care and Professional Issues
- Critical Care at 19% rewards postoperative management fluency
- Legal/Ethical and Emerging Topics is 5%: short but worth a focused pass

Key Takeaway
Let the name guide your time allocation. Cardiac, then Thoracic, then Critical Care deserve the bulk of your hours, and every topic should be studied through the lens of the heavily weighted tasks: diagnostics, interventions, and pharmacotherapy.
Frequently Asked Questions
It stands for Certificate of Added Qualifications in Cardiovascular and Thoracic Surgery, an NCCPA specialty credential for certified physician assistants, written as PA-C, CAQ-CVTS.
No. It supplements the PA-C credential and is not a separate initial PA certification. You must hold a current PA-C and maintain it for the CAQ to remain valid.
No. It is a PA specialty credential issued by NCCPA, not a physician surgical-board examination. Other credentials may share the "CVTS" abbreviation, so confirm the certifying body before relying on any information.
The blueprint lists Cardiac 38%, Thoracic 28%, Critical Care 19%, Vascular 10%, and Legal/Ethical Issues and Emerging Topics 5%. Separate task weights classify the same questions a second way.
Ten years, provided you maintain PA-C and licensure. Renewal requires 125 specialty Category I CME credits and passing the specialty exam, with the cycle-reset timing worth confirming directly with NCCPA.
