1.1 RCS Identity, Exam Format, Application, and Retesting
Key Takeaways
- RCS is CCI's cardiac sonography credential with an adult echo focus; RCCS, ARDMS RDCS, and CCI ACS are different credentials.
- The current RCS exam has 170 items in three hours, with 150 scored and 20 unidentified unscored items across traditional and innovative formats.
- A passing result is a scaled score of 650 on a 0–900 scale, not a fixed raw percentage.
- Eligibility, ATT timing, identification, rescheduling, and retesting each require exact compliance with current CCI and Pearson instructions.
Know the credential before studying for it
The Registered Cardiac Sonographer, or RCS, is Cardiovascular Credentialing International's credential for professionals working in echocardiography. In this guide, its clinical center is the adult transthoracic echo laboratory: acquiring and optimizing images, applying Doppler and other modalities, recognizing adult abnormalities, integrating clinical information, and communicating findings within the sonographer's role. Keep preparation adult-focused even though the matrix includes congenital-heart recognition.
| Label | What it means | Why the distinction matters |
|---|---|---|
| CCI RCS | Registered Cardiac Sonographer; the credential taught here | The current task matrix emphasizes adult echo performance, valves, hemodynamics, anatomy, physiology, and physics |
| CCI RCCS | Registered Congenital Cardiac Sonographer | This is a separate CCI credential centered on congenital cardiac sonography |
| ARDMS RDCS | Registered Diagnostic Cardiac Sonographer | This belongs to a different credentialing organization, with its own application and examination rules |
| CCI ACS | Advanced Cardiac Sonographer | This is an advanced-level credential, not another name for entry-to-practice RCS |
The RCS matrix is practice based. Performing Non-Imaging Responsibilities accounts for approximately 9% of the score, Echocardiographic Imaging 24%, Valvular Findings 25%, Anatomy, Physiology, and Hemodynamics 29%, and Ultrasound Physics 13%. The non-imaging domain matters from the first patient interaction: history review, prior-study review, order verification, ergonomics, patient preparation, preliminary reporting, and communication of significant findings.
Current examination facts
CCI lists the RCS as a three-hour, computer-based examination delivered year-round at Pearson test centers, subject to appointment availability. It contains 170 questions: 150 scored items and 20 unidentified unscored items distributed through the examination. Candidates receive 2 hours 50 minutes for questions and 10 minutes total for the tutorial and post-exam survey. Treat every item as scored because CCI does not identify the experimental items.
The detailed RCS examination page lists four formats: traditional single-answer multiple choice, multiple response, hot spot, and drag-and-place. A later generic exam-day sentence refers to four-choice questions; for preparation, the credential-specific item-format list is the more complete description. This guide uses several interactive structures to practice selection and organization even though a web matching exercise is not a claim about Pearson's exact interface.
Scores run from 0 to 900, and 650 is the passing scaled score. A scaled score is not the number or percentage correct; equating supports comparability across forms. CCI reports a 74% first-time RCS pass rate for 2025, but a population statistic neither predicts one candidate's outcome nor changes the passing standard. The current fee is $365, including a $100 nonrefundable filing and processing component.
Eligibility pathways are evidence pathways
Every applicant needs a high school diploma or equivalent, must satisfy one pathway, and must submit typed supporting documentation. Choose the pathway your evidence actually proves.
| Pathway | Core qualification | Typical proof identified by CCI |
|---|---|---|
| RCS235 | Health-science program graduate plus one year full-time or equivalent cardiac ultrasound work and at least 600 career cardiac ultrasound studies | Completion record plus employment and, when applicable, clinical-experience verification |
| RCS4 | Graduate of a programmatically accredited cardiac ultrasound program | Completion record and student verification; CCI separately explains pregraduation applicants |
| RCS5 | Graduate of a non-programmatically accredited cardiac ultrasound program with at least one year of specialty training and 800 required enrolled clinical hours | Completion, student, and clinical-experience records; hours completed after graduation or outside program requirements do not count toward 800 |
| RCS6 | Active ultrasound credential plus six months full-time or equivalent cardiac ultrasound work and at least 100 cardiac ultrasound studies | Active credential card plus employment and, when applicable, clinical-experience verification |
Do not blend pieces from several pathways unless CCI instructs you to do so. Names, dates, workload, study counts, signatures, and program status should agree across the application and verification letters. CCI's pathway tool is guidance, not an eligibility guarantee.
From application to result
Build a complete file before submission. CCI's FAQ describes typical processing as 15–30 business days but also posts a current portal-transition delay of 30–45 business days; incomplete or corrected applications can take longer. After approval, the current FAQ says the Authorization to Test email arrives within 24 hours. The ATT opens a 90-day eligibility window, after which the candidate schedules with Pearson. Do not promise an employer a date before Pearson confirms the appointment.
CCI allows one 90-day ATT extension. Current instructions direct a candidate to cancel any Pearson appointment first, observe the two-full-business-day cancellation deadline, and follow the live FAQ or account workflow for the request. Because operational instructions can change, use the current portal and CCI page rather than a saved screenshot. Ordinary rescheduling also requires contact with Pearson at least two full working days before the appointment.
On test day, bring two original, valid, unexpired IDs. The registered first and last names must match both IDs exactly. The primary ID must be government issued and include name, recognizable photo, and signature; the secondary must include at least name and signature or name and recognizable photo. Country-of-testing rules also apply.
Pearson provides an unofficial score report onsite. CCI says the official results letter, certificate, and wallet card arrive approximately 15 business days later. After an unsuccessful attempt, the candidate completes a new application and pays the full fee. An application may be resubmitted one day after testing, but the next attempt cannot occur until the 45-day waiting period is met. Previously submitted support need not be uploaded again when it still qualifies and was submitted within the preceding two years. Use that interval to diagnose content gaps, not merely repeat the same study routine.
Verify changing logistics
Fees, portal steps, processing delays, telephone numbers, and Pearson availability can change. Confirm them on the live CCI RCS and FAQ pages before applying, rescheduling, extending an ATT, or retesting.
