Part of the expanding PassProfessor catalog: The Registered Vascular Specialist (RVS) is Cardiovascular Credentialing International’s registry credential for professionals working in vascular ultrasound. The RVS examination is a three-hour, computer-based examination of 170 questions — 150 scored and 20 unscored — built on CCI’s job task analysis and examination matrix, reported on a scaled range of 0 to 900 with a total scaled score of 650 required to pass. Candidates qualify through CCI’s published education and experience pathways. PassProfessor’s RVS program is in development at $59.

The RVS is the credential that names vascular ultrasound as a specialty in its own right: the work spans arterial, venous, extracranial, abdominal and dialysis territories, and it is unforgiving of shallow preparation. PassProfessor’s RVS program is in development as part of the expanding PassProfessor catalog, built on the examination matrix and qualification pathways CCI publishes at cci-online.org for the Registered Vascular Specialist examination. The program will be priced at $59 when enrollment opens.
Which cardiovascular credential is this?
This page covers RVS — the Registered Vascular Specialist credential from Cardiovascular Credentialing International (CCI) — for professionals working in vascular ultrasound. Three clarifications. First, CCI’s cardiovascular credentials are distinct examinations with distinct eligibility pathways and distinct content matrices: RVS is not the RCIS, the RCS or the RCES, and experience or study toward one does not substitute for another’s blueprint. The RVS is also not the RPhS: the RPhS examines venous ultrasound specifically, while the RVS examines vascular ultrasound across all of its territories. Second, RVS is a professional credential awarded by CCI on passing its examination; it is not a state license, and CCI states it does not endorse or recommend any third-party review course or material — this program is independent preparation. Third, eligibility is documentary: CCI approves an application against a named qualification pathway, with typed supporting documentation, before any examination date exists. The RVS is CCI’s vascular ultrasound credential — not ARDMS’s RVT, which is a different body’s examination with its own prerequisites.

Who can take the RVS examination?
Every CCI applicant must hold a high school diploma or GED at the time of application, meet one of the credential’s qualification pathways, and provide typed documentation supporting the pathway claimed; CCI may request additional information, and processing a complete application takes a minimum of 15–20 business days. This credential’s pathways are:
- RVS235 — a graduate of a diploma, associate or baccalaureate health science program (cardiovascular technology, ultrasound, radiologic technology, respiratory therapy, nursing and similar), plus one year of full-time or full-time-equivalent work experience in vascular ultrasound, plus performance of a minimum of 600 vascular ultrasound studies in the applicant’s career, counting work and formal-program clinical experience.
- RVS4 — a graduate of a programmatically accredited program in vascular ultrasound.
- RVS5 — a graduate of a non-programmatically accredited program in vascular ultrasound with at least one year of specialty training including at least 800 clinical hours in the specialty.
- RVS6 — an active ultrasound credential holder with six months of full-time or full-time-equivalent work experience in vascular ultrasound and participation in a minimum of 100 vascular ultrasound studies.
CCI notes that the former RVS1 pathway was sunset effective June 30, 2023: first-time applicants on or after July 1, 2023 select from the pathways above. Once approved, CCI issues an Authorization to Test and a 90-day eligibility window opens; the examination is then scheduled with Pearson VUE. CCI also operates a pre-application process for criminal matters ($50, non-refundable) for applicants who need a determination before applying, as CCI publishes it.
The outline, area by area
| Content area | Share of the examination |
|---|---|
| Maintaining patient care and safety | 11% |
| Applying principles of physics and hemodynamics | 15% |
| Performing abdominal and visceral examinations | 10% |
| Performing extracranial and intracranial examinations | 20% |
| Performing arterial examinations of the upper and lower extremities | 22% |
| Performing venous examinations of the upper and lower extremities | 19% |
| Performing hemodialysis examinations | 3% |
What does Maintaining patient care and safety cover? (11%)
The professional frame around the vascular study: identifying and assessing the patient; verifying the appropriateness of the examination and recognizing contraindications; eliciting the history and risk factors; positioning; identifying and documenting critical findings; standard and universal precautions and sterile technique; ergonomic safety; quality assurance and improvement; bioeffect safety and equipment care; and generating the preliminary findings for physician interpretation. The examination treats the report and the escalation as part of the specialist’s own work, not someone else’s.
How should you prepare for Maintaining patient care and safety? Survey the area early, note where your reasoning breaks down, and return with focused practice rather than rereading. The work here rewards applied judgment in realistic situations, so pair every block of reading with timed practice, then examine why each wrong option was wrong. Keep a running list of the distinctions this area tests most finely, and revisit the area in mixed practice before you test, so competence does not depend on knowing the topic in advance.
What separates strong candidates in Maintaining patient care and safety? Usually not more facts, but cleaner sequencing: recognizing the decisive feature of a situation first, discarding options that are true but not responsive, and choosing the action the situation calls for now rather than eventually. When you review practice in this area, classify every miss before you move on — knowledge gap, misread situation, or wrong priority — because each class has a different repair. Revisit the area in mixed practice before you test; competence that only appears when you know the topic in advance is not yet examination competence.
What does Applying principles of physics and hemodynamics cover? (15%)
The instrument understood, not just operated: setting up the equipment — transducer selection and examination presets; obtaining the optimal gray-scale image; applying hemodynamic principles; and optimizing each data channel in turn — pulsed-wave Doppler, continuous-wave Doppler, color Doppler and power Doppler — while detecting artifacts and reasoning about their causes. Physics and hemodynamics are the lens through which every later territory is read, and the matrix weights them accordingly.
How should you prepare for Applying principles of physics and hemodynamics? Start with the area’s core decisions and work outward to its edge cases. Preparation should alternate short reading blocks with timed questions on the same material, because retrieval under time pressure is the skill the sitting itself demands. Log every miss by cause — knowledge gap, misread situation, or wrong priority — since each cause has a different repair, and lumping them together hides the pattern your next study block should attack.
What separates strong candidates in Applying principles of physics and hemodynamics? Depth shows as discrimination: the strong candidate separates the option that is merely plausible from the option the facts of the case actually support, and can say why the plausible one fails. Train that discrimination deliberately — after every practice block, write one line per miss naming the feature of the situation you underweighted. Over weeks that log becomes the most personal syllabus you own.
What does Performing abdominal and visceral examinations cover? (10%)
The central vascular territories: renal duplex; mesenteric duplex; abdominal aortoiliac duplex, including endovascular repair; iliocaval duplex, including venous stents; and organ transplant duplex for kidney and liver. Each study is examined as a performance — windows, optimization and the judgment of what the study must answer — in anatomy where depth, bowel gas and post-intervention change punish shallow technique.
How should you prepare for Performing abdominal and visceral examinations? Treat this area as a set of decisions, not a set of facts: for each topic, ask what the practitioner must notice first, what must happen next, and what must never happen. Practise in timed blocks, review every error the same day, and return to the area after a gap of several days so that retention, not recognition, is what carries you.
What separates strong candidates in Performing abdominal and visceral examinations? Command of this area looks quiet on the surface: fewer rereads, steadier pacing, and answers chosen for the situation presented rather than for the situation remembered from a textbook example. Build it by practising against varied presentations of the same underlying problem, so the principle, not the surface story, is what you learn to recognize.
What does Performing extracranial and intracranial examinations cover? (20%)
A fifth of the examination on the vessels of the neck and brain: extracranial duplex; transcranial Doppler, imaging and non-imaging; and extracranial post-intervention duplex. Carotid disease, vertebral flow and intracranial assessment carry direct stroke implications, and the matrix weights the territory accordingly — criteria application and the recognition of when findings change management are the discriminating skills here.
How should you prepare for Performing extracranial and intracranial examinations? Build a one-page map of this area before drilling it: its central concepts, its recurring traps, and the situations in which its rules change. Then work timed practice against that map, correcting the map whenever a question exposes a gap in it. Finish the area with mixed practice alongside earlier areas, so the knowledge has to be selected, not merely recalled.
What separates strong candidates in Performing extracranial and intracranial examinations? Strong candidates protect this area’s marks by pacing: they bank time on the items they know cold and spend it where the situation is genuinely ambiguous, instead of bleeding minutes early and rushing late. Simulate that discipline in practice — set a per-block clock, mark-and-move on the second reread, and only return with time in hand.
What does Performing arterial examinations of the upper and lower extremities cover? (22%)
The examination’s largest area: extremity arterial duplex; post-intervention assessment of bypass grafts and stents; segmental pressures and ankle-brachial indices; pulse volume recording; exercise testing; specialty physiologic testing — Allen’s test, cold sensitivity, thoracic outlet and popliteal entrapment; and assessment for post-procedure arterial complications: pseudoaneurysm, arteriovenous fistula and hematoma. The duplex and physiologic halves of vascular testing meet in this area, and both are examined.
How should you prepare for Performing arterial examinations of the upper and lower extremities? Survey the area early, note where your reasoning breaks down, and return with focused practice rather than rereading. The work here rewards applied judgment in realistic situations, so pair every block of reading with timed practice, then examine why each wrong option was wrong. Keep a running list of the distinctions this area tests most finely, and revisit the area in mixed practice before you test, so competence does not depend on knowing the topic in advance.

Revisit the area in mixed practice before you test; competence that only appears when you know the topic in advance is not yet examination competence.
What does Performing venous examinations of the upper and lower extremities cover? (19%)
The venous half of peripheral vascular practice: extremity venous duplex; lower-extremity venous insufficiency testing; vein mapping; and peri-procedural venous assessment, including ablation and PICC-related studies. Compression technique, reflux assessment and the mapping discipline that procedural planning depends on are examined as performances — the candidate who can only repeat a protocol, without adapting it to the leg in front of them, is exactly who this area separates out.
How should you prepare for Performing venous examinations of the upper and lower extremities? Start with the area’s core decisions and work outward to its edge cases. Preparation should alternate short reading blocks with timed questions on the same material, because retrieval under time pressure is the skill the sitting itself demands.

Train that discrimination deliberately — after every practice block, write one line per miss naming the feature of the situation you underweighted. Over weeks that log becomes the most personal syllabus you own.
What does Performing hemodialysis examinations cover? (3%)
The smallest area by weight and a complete specialty in miniature: the hemodialysis access examination, and pre- and post-operative testing around access creation and revision. Three percent is roughly five scored questions — few enough to neglect, specific enough that neglecting them is a choice the results will show.
How should you prepare for Performing hemodialysis examinations? Treat this area as a set of decisions, not a set of facts: for each topic, ask what the practitioner must notice first, what must happen next, and what must never happen. Practise in timed blocks, review every error the same day, and return to the area after a gap of several days so that retention, not recognition, is what carries you.

How is the RVS examination scored?
CCI reports total scores on a scale from 0 to 900, and a total scaled score of 650 is required to pass. CCI is explicit about what that number is not: a scaled score does not equal the number or percentage of questions answered correctly. The number of correct answers needed to reach 650 was determined through a standard-setting (passing-score) study, and CCI reviews the passing score periodically with panels of experts from the specialty to assure its validity. Your score is based on the 150 scored questions; the 20 unscored questions are randomly distributed and unidentified, and exist so CCI can evaluate items for future examinations. At the test center you receive an unofficial report with your total score, your pass/fail status and a breakdown of the percentage of questions you answered correctly in each content area — that breakdown, not the scaled number, is the diagnostic tool for a candidate who must sit again.
An honest note about CCI’s innovative item types
Alongside traditional multiple-choice questions — four options, one correct or best answer — CCI examinations include innovative item types: multiple-response items, where two or three answers are correct from a list of four to six and the item tells you how many to select; hot-spot items, where you click one specific area of an image; and drag-and-place items, where labels must be dragged into the correct boxes on an image. PassProfessor’s program is question-based preparation: it trains the knowledge and clinical judgment those items examine, in question form — it does not reproduce CCI’s hot-spot or drag-and-place mechanics, and candidates should expect to meet those formats for the first time, as formats, inside CCI’s own published descriptions and self-assessment materials. The knowledge underneath them is the same knowledge this program drills, organized by CCI’s own examination matrix.
What does the path from application to sitting look like?
CCI’s process is documentary before it is anything else, and candidates lose more time to paperwork than to the examination itself. You apply through your CCI online account, selecting the credential and the qualification pathway you claim, with the supporting documents — transcripts or completion certificates, employment verification letters, and clinical experience letters where the pathway requires them — uploaded as typed documentation. CCI reserves the right to request additional information, and processing a complete application takes a minimum of fifteen to twenty business days, so the application belongs weeks ahead of any intended test date, not days. Once approved, you receive an Authorization to Test by email, typically within two business days, and your ninety-day eligibility window opens: the examination must be scheduled with Pearson VUE and taken inside it. One extension of ninety days may be requested through your CCI account; if the examination is not taken by the end of the extension, the fee is forfeited and you reapply. Rescheduling runs through Pearson VUE and requires contact at least two full working days before the appointment — miss that deadline and the appointment cannot be moved. On the day, bring the two forms of identification CCI’s policy requires, with names matching your registration exactly, and expect the unofficial score report — total score, pass/fail status and your per-area percentages — before you leave the center. Plan backwards from your target date: documents first, application second, and a study plan whose final timed phase lands inside the eligibility window, not before it. Candidates who have not tested under CCI before should also read CCI’s published examination-day and identification rules in full before the appointment — the two-ID requirement and the exact-name rule are administrative, unforgiving, and entirely avoidable as failure causes.
How should you plan your preparation?
Phase one — map the examination (week one). Read the outline end to end and mark, honestly, the areas where your training is deep and the areas where it is thin. The weights in the table above tell you what the examination itself values; your map tells you where your hours buy the most.
Phase two — build by area. Work one content area at a time: read the authoritative material for the area, then take timed practice on it the same day, while the distinctions are still warm. Log every miss by cause — knowledge gap, misread situation, or wrong priority — because each cause has a different repair.
Phase three — mix and lengthen. Once every area has been touched, practice stops being organized by area: mixed blocks force you to select the right framework before you apply it, which is the skill the sitting actually tests. Lengthen blocks toward the real sitting’s duration so stamina is trained, not hoped for.
Phase four — simulate and repair. Sit full timed practice under examination conditions, review every error the same day, and spend the remaining days on the two weakest areas your results identify. Book the real sitting when full-length practice is consistently strong across areas, not when one favourite area is polished.
Frequently asked questions
What is the RVS credential? The Registered Vascular Specialist: CCI’s credential for professionals working in vascular ultrasound, awarded on passing CCI’s 170-question examination after qualifying through one of CCI’s published pathways.
How many questions are on the examination? 170 questions in a three-hour sitting: 150 scored and 20 unscored. Two hours and fifty minutes are allotted to the questions, with ten minutes for the tutorial and post-exam survey. The unscored questions are not identified.
What score do I need to pass? A total scaled score of 650 on CCI’s 0–900 scale. CCI states that scaled scores do not equal a number or percentage of correct answers; the standard was set by a standard-setting study and is reviewed periodically with specialty expert panels.
Does the examination include non-multiple-choice items? Yes. Alongside traditional multiple-choice items, CCI uses innovative item types — multiple-response, hot-spot and drag-and-place items. This program is question-based preparation for the knowledge those items examine; it does not reproduce the hot-spot or drag-and-place mechanics. The exam guide covers this in full.
How do I know if I am eligible? CCI publishes named qualification pathways combining education, credentials and experience, summarized in the eligibility section above, with a pathway tool on CCI’s site. You must also hold a high school diploma or GED and document the pathway you claim; CCI approves the application before your 90-day testing window opens.
Are these CCI’s actual examination questions? No. When this program opens, its questions will be original practice questions written by PassProfessor to CCI’s published examination matrix. We never use actual examination items, recalled items, or another provider’s material. CCI does not endorse third-party review materials, and this program claims no endorsement.
How long do I have to test once CCI approves me? Approval opens a 90-day eligibility window: CCI emails your Authorization to Test, typically within two business days of approval, and the examination is scheduled with Pearson VUE inside that window. One 90-day extension may be requested through your CCI account.
Is the RVS the same as the RVT or the RPhS? No, on both counts. The RVT is ARDMS’s vascular credential — a different body, a different examination and different prerequisites. The RPhS is CCI’s own specialty credential for venous ultrasound specifically; the RVS covers vascular ultrasound across arterial, venous, extracranial, abdominal and hemodialysis territories. Each credential is earned on its own examination.
What happens if I do not pass? Your unofficial report at the test center breaks down the percentage of questions answered correctly in each content area of the matrix — that breakdown is your study plan for the next sitting, because it shows which duties, not just which topics, cost you. Reapplication and rescheduling follow CCI’s published policies; rescheduling with Pearson VUE requires contact at least two full working days ahead.
How is the credential maintained? As CCI publishes it: a first renewal in the following year carries a renewal fee and a Code of Ethics signature, with no CEU requirement; thereafter the credential renews triennially with the renewal fee and 36 CEUs per cycle for registry-level credentials, 30 of them cardiovascular-related.
What do CCI’s own self-assessment examinations do? CCI publishes self-assessment examinations whose items follow the approximate proportions of the real examination matrix. They return a performance profile — your percentage of correct responses by content area — but no report of missed items and no feedback on incorrect responses, and CCI states their results neither guarantee nor indicate success on the real examination. Used well, they are a matrix-proportioned readiness check near the end of preparation, not a study method.
What happened to the RVS1 pathway? CCI sunset it: the RVS1 qualification prerequisite ended effective June 30, 2023, and first-time applicants on or after July 1, 2023 select from RVS235, RVS4, RVS5 or RVS6.
When will enrollment open? The program is in development. Join the notify list on this page and we will email you when enrollment opens at the $59 program price.
