CCI RCS Exam Guide 2026: Adult Echo Prep That Matches the Current Blueprint
The CCI Registered Cardiac Sonographer (RCS) exam is for professionals working in adult echocardiography. It validates the knowledge and task performance needed to produce diagnostic-quality echo studies, evaluate valves, interpret anatomy and hemodynamics, optimize ultrasound imaging, and communicate clinically significant findings.
The official CCI page lists the RCS passing score as 650 scaled, not 670 or 400 as some older or third-party summaries state. The current exam is a 3-hour computer-based exam with 170 questions, including 150 scored and 20 unscored, administered at Pearson VUE test centers after CCI approves your application and issues Authorization to Test.

Official RCS Content Weights
CCI bases the RCS exam on a Job Task Analysis. The official task weights are:
| RCS Content Area | Approx. % of Exam Score | What to Practice |
|---|---|---|
| Evaluating Anatomy, Physiology, and Hemodynamics | 29% | Chambers, systolic and diastolic function, cardiomyopathies, ischemia, pericardial disease, great vessels, pulmonary hypertension, masses, congenital findings, devices, strain, and infiltrative disease |
| Evaluating Valvular Echocardiographic Findings | 25% | AS, AR, MS, MR, TR, TS, PR, PS, prosthetic valves, endocarditis, gradients, valve area, regurgitation severity, and hemodynamics |
| Performing Echocardiographic Imaging | 24% | 2D TTE, M-mode, color Doppler, spectral Doppler, contrast, agitated saline, stress echo, TEE assistance, strain, 3D TTE, and 3D TEE |
| Applying the Physics of Ultrasound | 13% | Waveforms, artifacts, resolution, frame rate, Doppler optimization, color optimization, 2D, 3D, and contrast imaging |
| Performing Non-Imaging Responsibilities | 9% | History review, prior studies, order verification, ergonomics, patient preparation, reports, and communication of significant findings |
This is why adult echo prep must be visual and quantitative. You need to recognize views and pathology, but you also need to calculate and interpret gradients, valve areas, E/e', LAVi, TAPSE, S', FAC, wall motion, Doppler artifacts, and stress echo findings.
Who Can Sit for the RCS Exam? Eligibility Pathways
CCI evaluates RCS applicants through its online Pathways tool, but the substance of the routes breaks down into four general tracks:
- Health-science degree route. A diploma, associate, or bachelor's degree in a health-science field (cardiovascular technology, ultrasound, radiologic technology, respiratory therapy, or nursing) plus 1 year of full-time cardiac ultrasound work experience and a minimum of 600 documented cardiac ultrasound studies.
- Accredited program route. Graduation from a programmatically accredited cardiac ultrasound program, with no separate post-graduation experience requirement.
- Non-accredited program route. Graduation from a non-accredited cardiac ultrasound program with at least 1 year of specialty training and a minimum of 800 clinical hours completed during the program.
- Credentialed-sonographer route. An active ultrasound credential plus 6 months of full-time cardiac ultrasound experience and a minimum of 100 documented cardiac ultrasound studies.
Every route requires at least a high school diploma or GED, and CCI may request additional documentation before issuing Authorization to Test. Run your exact background through CCI's official Pathways tool before you apply — the general routes above can have edge cases CCI evaluates case by case.
RCS vs RDCS: Which Credential Are You Studying For?
RCS is issued by CCI. RDCS is issued by ARDMS. Many employers accept either adult echo credential, but they are different exam programs with different application systems and exam requirements. CCI RCS is a one-part CCI registry exam after you qualify through a CCI pathway. ARDMS RDCS adult echo candidates must satisfy ARDMS requirements and pass the ARDMS specialty path.
If you are applying for a job or clinical site requirement, read the exact wording. If it says RCS, use CCI. If it says RDCS, use ARDMS. If it says RCS or RDCS, either may satisfy the credential requirement, but verify with the employer or program.

High-Yield RCS Formulas and Thresholds to Know
- Simplified Bernoulli equation: pressure gradient equals 4V squared.
- Continuity equation for aortic valve area: LVOT area times LVOT VTI divided by AV VTI.
- Simpson biplane EF and how foreshortening changes volume estimates.
- Diastolic function inputs: E/A, septal and lateral e', E/e', LAVi, and TR velocity.
- Severe aortic stenosis pattern: high Vmax, high mean gradient, and AVA below 1.0 cm2, interpreted with flow state.
- Tamponade signs: chamber collapse timing, IVC plethora, and respiratory inflow variation.
- Constriction clues: septal bounce, respiratory variation, and hepatic vein expiratory diastolic reversal.
Exam-Day Strategy for Hot Spot, Drag-and-Place, and Image Items
The RCS exam mixes traditional multiple choice with innovative item types, and those formats reward a different habit than text-only questions.
For hot spot items, name the structure or measurement point out loud before you click. A wrong click on the right image still counts as wrong, so confirm the view (PLAX vs PSAX vs apical) and the cardiac cycle phase (systole vs diastole) before you mark a location.
For drag-and-place items, build the sequence or labeling from the anchor points you are most certain of first, then fill in the remaining slots by elimination. Do not leave the most confident answers for last; lock them in to narrow the remaining choices.
For multiple-response items, treat each option as its own true/false statement rather than searching for "the" answer. Severity-grading questions (aortic stenosis, mitral regurgitation, diastolic dysfunction) are common multiple-response traps because two findings can both be technically true while only one combination matches the official severity criteria.
For calculation-heavy stems (continuity equation, Bernoulli, Simpson EF, PISA), write down what each given value represents before you plug it into a formula. Most missed calculation questions come from substituting the wrong VTI or velocity, not from the algebra itself.
Common RCS Mistakes
- Using 670 as the passing score. CCI's current RCS page states that a scaled score of 650 is required to pass.
- Overstudying physics while underdrilling valves. Physics matters, but valvular findings are 25% and hemodynamics/anatomy is 29%.
- Memorizing thresholds without image context. The exam tests how echo measurements are acquired, not only what the numbers mean.
- Ignoring innovative item types. Hot spot and drag-and-place items punish weak anatomy and view recognition.
- Skipping non-imaging responsibilities. Patient history, order verification, ergonomics, reporting, and communication are a real 9% of the exam.
- Not scheduling promptly after ATT. Your CCI Authorization to Test starts a 90-day eligibility window, with only one 90-day extension available.
- Assuming a quick retake. CCI requires a minimum 45-day wait and a brand-new application with fees before you can retest.
If You Don't Pass: CCI's Retake Policy
CCI's official policy requires a minimum 45-day waiting period before a candidate can sit for the RCS exam again. You cannot simply rebook the next available seat; you must submit a new application and the required fees. If your supporting documentation was submitted within the last two years and still meets current requirements, CCI generally does not require you to resubmit it, but you should confirm this with CCI directly when you reapply. Build the 45-day window into your plan rather than discovering it after a missed pass — use that time for focused remediation on your weakest domain rather than a full re-study of everything.

Final Two-Week Readiness Plan
Two weeks before exam day, stop measuring progress by pages reviewed and start measuring it by repeatable performance. Your target is not one lucky high score; it is several timed blocks where the same weak area no longer appears in your miss log.
During week one, alternate blocks: one targeted weak-domain set, one mixed timed set, one review block, and one closed-book recall session where you write formulas, severity thresholds, and view-recognition rules from memory before checking them against the official content outline.
During the final week, reduce new material. Keep daily contact with your hardest domain, but shift toward pacing and clean execution on hot spot and drag-and-place items specifically, since those formats punish hesitation more than text-only questions. Confirm your testing-center identification requirements and Authorization to Test window with CCI before exam day so logistics do not disrupt your performance.
Passing the RCS exam is less about finding a secret resource and more about running a tight loop: verify facts against CCI's current page, drill the highest-weighted domains (anatomy/hemodynamics and valves), practice the innovative item types deliberately, and review why each missed answer was wrong. Keep that loop tight, and every practice session has a job.
