The Headline Number: 56% for 2025
Cardiovascular Credentialing International (CCI) reports a 56% first-time pass rate for the Registered Vascular Specialist (RVS) examination for 2025. That figure appears in CCI's FAQ and is echoed on its student-community page. It is the most concrete, citable data point available about how candidates fare on this credential, and it is the anchor for everything in this article.
Put plainly: in 2025, roughly 56 of every 100 first-time RVS candidates passed, which means a little under half did not. For a registry-level vascular ultrasound exam, that is a sobering number, and it tells you the exam rewards real preparation rather than familiarity with the work alone. If you are still deciding how seriously to take it, our guide on how hard the RVS exam is unpacks the difficulty from several angles.
How to Read a First-Time Pass Rate Correctly
A first-time pass rate measures a specific population: candidates sitting the exam for the first time. It excludes retakers, who tend to be a different group. That matters in two ways.
- It is a floor-setting statistic, not a ceiling. Candidates who fail once and return after additional study are not counted in the first-time figure, so the overall proportion of people who eventually earn the credential is a separate question the published data does not answer.
- It reflects one year. The 2025 figure should not be projected forward as a guarantee for 2026 test-takers. Pass rates can shift with cohort composition, and CCI's current examination matrix was reviewed in October 2026, so treat the 56% as a benchmark rather than a forecast.
- It blends different candidates. RVS applicants arrive through several pathways, from working sonographers with documented clinical volume to recent graduates of accredited programs. A single blended rate hides those differences.
The practical takeaway is not to panic or to be complacent. A 56% rate means the exam is passable by well-prepared candidates and genuinely unforgiving of underprepared ones. For a plan that matches that reality, see our RVS study guide for passing on the first attempt.
Why 650 on a 0-900 Scale Is Not a Percentage
One of the most common misreadings of pass-rate data is assuming the passing mark is a raw percentage. It is not. The RVS passing score is 650 on CCI's 0-900 scaled-score range. A scaled score converts your raw performance onto a common reporting scale so results remain comparable across different exam forms.
That has two consequences for how you interpret the 56% figure and plan your own attempt:
- You cannot reverse-engineer "I need X questions right" from 650. The conversion from raw to scaled performance is CCI's, and it is not a simple proportion.
- You cannot treat practice-test percentages as a direct prediction. A practice score is a useful signal about readiness, not a forecast of your scaled score.

Where First Attempts Likely Fall Apart: The Seven Domains
CCI does not publish a failure breakdown by domain, so we cannot say which section candidates miss most often. What we can do is look at the exam's published structure and reason about where preparation effort has the most leverage. The percentages below are CCI's published approximate shares of exam score from the current live RVS Examination Matrix and Task List, reviewed October 14, 2026.
| Domain | Approx. share of score |
|---|---|
| Domain 1: Maintaining Patient Care and Safety | 11% |
| Domain 2: Applying Principles of Physics and Hemodynamics | 15% |
| Domain 3: Performing Abdominal/Visceral Examinations | 10% |
| Domain 4: Performing Extracranial/Intracranial Examinations | 20% |
| Domain 5: Performing Arterial Examinations of the Upper and Lower Extremities | 22% |
| Domain 6: Performing Venous Examinations of the Upper and Lower Extremities | 19% |
| Domain 7: Performing Hemodialysis Examinations | 3% |
The Big Three: Domains 5, 4 and 6 (61% combined)
Upper/lower-extremity arterial examinations carry the single largest weight at 22%, followed by extracranial/intracranial at 20% and extremity venous at 19%. A candidate who is shaky on any one of these is exposed on a large slice of the exam.
- Arterial: waveform interpretation, stenosis criteria, and the protocols you perform on the extremities
- Cerebrovascular: carotid and intracranial exam technique, velocity-based interpretation and the indications behind each study
- Venous: thrombosis evaluation, reflux assessment and protocol choices for upper versus lower extremity
Domain 2: The Hidden Differentiator (15%)
Applying Principles of Physics and Hemodynamics is where this exam differs from a pure protocol test. Because the RVS is a single, one-part registry-level exam rather than a separate physics exam followed by a specialty exam, physics and hemodynamics are folded into the same sitting. Candidates who learned the work by doing it but never revisited the underlying principles are the ones most likely to be surprised here.
The Smaller Domains Still Count
Maintaining Patient Care and Safety (11%), Performing Abdominal/Visceral Examinations (10%) and Performing Hemodialysis Examinations (3%) add up to 24% of the score. Ignoring them because they are smaller is a classic way to lose points you could have banked. Hemodialysis is the smallest slice at 3%, but it is still tested.
Format and Time Pressure: 170 Questions in 170 Minutes
Pass-rate data is partly a story about exam mechanics. The RVS is delivered at Pearson VUE test centers year-round and contains 170 questions: 150 scored and 20 unidentified, randomly distributed unscored items. You are given 170 minutes (2 hours 50 minutes) to answer them, and the three-hour appointment includes an additional 10 minutes for a tutorial and survey.
That works out to about one minute per question, which is tight for items that require reading an image or working through a calculation. A few format details shape how candidates should practice:
- Four item formats: single-best-answer multiple-choice, multiple response, image hot spot and drag-and-place. Do not assume the exam is multiple-choice only; the hot-spot and drag-and-place items demand visual and procedural fluency rather than recognition.
- Unscored items are invisible. You cannot tell which 20 questions do not count, so treat every item as scored.
- You can skip and mark for review. Use this deliberately: bank the quick wins first, then return to time-consuming image items.
- Closed book, with tools supplied. An on-screen calculator and an erasable board are provided, and two valid identification documents are required at check-in.
Key Takeaway
Because roughly one minute per question is all you get, train under timed conditions with image-based and drag-and-place items, not just text recall. Pacing failures are an avoidable reason to land below 650.
Eligibility Pathways and Who Sits the Exam
The 56% figure covers a mixed population, and it helps to know who that population is. All applicants need a high school diploma or GED plus one qualifying pathway, supported by typed documentation and the applicable medical or program-director verification letters. The current pathways are:
| Pathway | Who it is for | Core requirement |
|---|---|---|
| RVS235 | Experienced practitioners with health-science education | Health-science diploma, associate or baccalaureate qualification; one year FTE vascular ultrasound work; at least 600 vascular studies |
| RVS4 | Graduates of programmatically accredited vascular ultrasound programs | Graduation from the program; pregraduation testing possible with documentation, but credential release depends on graduating |
| RVS5 | Graduates of non-programmatically accredited vascular ultrasound programs | At least one year of vascular training and 800 clinical hours completed within the program |
| RVS6 | Already credentialed in ultrasound | Active ultrasound credential; six months FTE vascular ultrasound work; participation in at least 100 vascular studies |
RVS1 closed to first-time applicants on July 1, 2023, so you will not find it available to new candidates. Full detail is in our RVS requirements guide. Note that these pathways reflect very different levels of hands-on exposure, which is one reason a single blended pass rate should be read cautiously.
Retake Economics: Fee, Window and Waiting Period
The 44% of first-time candidates who did not pass in 2025 faced a concrete set of costs and constraints, and understanding them is part of understanding the stakes of a first attempt.
- Exam fee: $365 USD, which includes a $100 nonrefundable application-processing portion.
- Testing window: Your Authorization to Test opens a 90-day window in which to sit the exam.
- Retakes: A new application, the examination fee again and a 45-day wait before you can retest.
In other words, a failed first attempt costs you another full fee and at least a month and a half of calendar time, before you factor in re-studying. That is a strong financial argument for preparing thoroughly the first time. Our RVS certification cost breakdown covers the full pricing picture, and RVS exam dates and scheduling explains how the testing window works in practice. CCI's published processing estimates and rescheduling deadlines are not fully consistent across its materials, so confirm the applicable deadlines directly with CCI and Pearson VUE rather than relying on any unconditional turnaround promise.
Sequencing Your Prep Around the Domain Weights
Generic study advice is plentiful. What is specific to the RVS is how to allocate effort across its seven domains. One reasonable way to sequence an eight-week plan, weighted to the published shares, looks like this:
Physics, Hemodynamics and Patient Safety
- Domain 2 (15%) first, because it underpins interpretation in every other domain
- Domain 1 (11%) alongside it, since safety and patient-care items are quick to consolidate
The Large Vascular Domains
- Domain 5 arterial extremity (22%), Domain 6 venous extremity (19%) and Domain 4 extracranial/intracranial (20%)
- Spend the most time on image-based and drag-and-place practice here
Abdominal/Visceral and Hemodialysis
- Domain 3 (10%) and Domain 7 (3%), so the smaller domains do not get skipped
Timed Full-Length Practice
- Simulate 170 questions in 170 minutes and review every miss against its domain
The logic is simple: build the physics foundation first, then spend the bulk of your time where 61% of the score lives, then close the gaps. A single-page recap is useful in the final days, and our RVS cheat sheet is designed for exactly that.
After You Pass: Credential Period and Renewal
Passing is the start of a maintenance cycle, and it is worth knowing before you commit. The initial credential period is 9-12 months. The first renewal costs $165 and requires a Code of Ethics attestation but no CEUs. After that you renew every three years for $165, attest to the Code of Ethics and complete 36 CEUs, at least 30 of them cardiovascular-related. The remaining CEUs must be medical-related under CCI's dedicated CEU policy. CCI's renewal page and its dedicated CEU requirements word the last point differently, so plan on medical-related credit rather than assuming any topic will count.

Frequently Asked Questions
CCI reports a 56% first-time pass rate for the Registered Vascular Specialist exam for 2025. This is the figure published in CCI's FAQ and confirmed on its student-community page.
No. The passing score is 650 on CCI's 0-900 scaled-score range. It is a scaled score, not a percentage of questions answered correctly, so you cannot convert it into a simple number of correct answers.
By published weight, extremity arterial examinations (22%), extracranial/intracranial examinations (20%) and extremity venous examinations (19%) make up the largest share. Physics and hemodynamics at 15% is also significant because it supports interpretation across the exam.
You must submit a new application, pay the examination fee again and wait 45 days before retesting. Your Authorization to Test opens a 90-day window for each attempt.
Yes. Of the 170 questions, 150 are scored and 20 are unidentified, randomly distributed unscored items. Because you cannot tell which are which, answer every question with full effort.
The 56% first-time pass rate is a useful reality check, not a verdict on your chances. Candidates who align their preparation with the published domain weights, practice under real time pressure and understand the format are positioned to land on the right side of that statistic. When you are ready to test yourself, take a timed run on the RVS Exam Prep practice test site and review the broader credential background in our what is RVS certification overview.
