RCS Pass Rate 2026: What the Data Shows

What the Published Numbers Say

If you are searching for the Registered Cardiac Sonographer pass rate for 2026, the honest answer starts with a limitation: Cardiovascular Credentialing International (CCI) has not published a 2026 cohort rate, and no sample size accompanies the figures it does release. What exists are two first-time-candidate figures from different reporting years.

These two numbers are not contradictory. They describe different years. A four-point difference between cohorts is the kind of movement you would expect from year-to-year variation in who sits the exam, and neither figure tells you whether the exam itself became easier or harder. If you want a broader view of difficulty beyond the rate, see our guide on how hard the RCS exam is.

How to Read a Pass Rate Correctly

A headline percentage is useful for orientation but weak for planning. Three cautions apply to the RCS figures.

The figures are first-time rates

CCI reports the rate for first-time candidates. It does not, in the sources reviewed, break out repeat test-takers. That matters because a first-time rate describes the cohort that prepared once and sat once; it does not tell you how many people eventually earn the credential after a retake.

The figures are not 2026 data

The most recent number covers 2025. Treating it as a 2026 forecast is reasonable as a rough guide, but it is an assumption, not a published fact. CCI had not issued a newer rate when this article was researched in October 2026.

A pass rate cannot tell you your odds

Roughly three in four first-time candidates passing in 2025 says little about an individual whose preparation, clinical exposure, and test familiarity differ from the average. The candidates who sit the RCS exam arrive through several different eligibility pathways, which brings us to who the number actually describes.

650 on a 0-900 Scale Is Not a Percentage

The passing standard for the RCS exam is a scaled score of 650 on a 0-900 range. A common mistake is to convert that into a percentage-correct target. CCI explicitly states that scaled scores do not equal raw correct-answer counts or percentages, so 650 is not 72.2% correct, even though 650 divided by 900 happens to produce that figure.

Scaling exists so that scores remain comparable across different forms of the exam. Because individual questions vary in difficulty, the number of items you need to answer correctly can shift from one exam form to another. The practical consequence is that you should not study toward a magic raw percentage. Instead, aim for consistent strength across all five content areas. Our dedicated article on the RCS passing score walks through this in more detail.

Who the Numbers Actually Describe

RCS candidates are not a uniform group. CCI requires a high-school diploma or GED plus one documented qualification pathway, and the pathways differ sharply in how candidates have prepared.

• RCS235: a health-science diploma, associate, or baccalaureate program plus one year of full-time-equivalent cardiac-ultrasound work and at least 600 cardiac studies.
• RCS4: graduation from a programmatically accredited cardiac-ultrasound program.
• RCS5: a non-programmatically accredited cardiac-ultrasound program with at least one year of specialty training and 800 required in-program clinical hours.
• RCS6: an active ultrasound credential plus six months of full-time-equivalent cardiac-ultrasound work and at least 100 studies.

The RCS1 pathway ended on June 30, 2023 for new applicants, so it is not an option today. Eligible students can also test before graduation with program-director authorization, but the credential does not become active until educational completion is verified.

Because first-time candidates include recent graduates, working sonographers with years of bedside experience, and credentialed professionals adding cardiac ultrasound, the aggregate rate blends very different starting points. The detailed eligibility rules, including how full-time equivalent is defined and which clinical hours count, are covered in RCS requirements.

Where Candidates Lose Points: The Five Domains

CCI does not publish a domain-by-domain pass analysis, so any claim about which area fails the most candidates would be invented. What CCI does publish is the weighting of the five content domains. Those weights are labeled approximate, and the published percentages total 100%. They tell you where the scored questions are concentrated, which is the most defensible guide to where preparation time pays off. For a full walkthrough, see the complete guide to all five RCS content areas.

Domains 3 and 4 together account for 54% of the exam, and Domain 2 adds another 24%. A candidate who is excellent at physics but shaky on valves and hemodynamics is exposed where the points are. A reference for rapid review of these areas is our RCS cheat sheet.

Format, Clock, and Test-Day Mechanics

The exam format influences how candidates perform independent of content knowledge, and it is worth understanding before you schedule.

A few details deserve emphasis. The 20 unscored questions are indistinguishable from scored ones, so you cannot safely coast on any item. The mix of image hot spots and drag-and-place items means you must be able to identify structures and findings on an image rather than only recognize terminology. CCI's page also contains a later paragraph describing four-option, single-correct-answer questions; that wording is inconsistent boilerplate and does not remove the innovative formats from the exam. There is no separate hands-on scanning assessment, and adaptive delivery is not specified.

Test-day conditions are center-proctored with no personal books or notes unless the sponsor expressly authorizes them. An on-screen pop-up calculator and an erasable board are provided, and two acceptable IDs are required. Candidates receive a 90-day eligibility window through the Authorization to Test. Scheduling rules and rescheduling deadlines are covered in RCS exam dates.

Retake Math: Cost and Timing of a Failed Attempt

With roughly one in four first-time candidates not passing in 2025, the cost of a miss is relevant. The exam fee is USD 365, which includes a USD 100 non-refundable application-processing portion. No member versus nonmember price distinction is published. A failed attempt requires a brand-new application and the full fee again, plus a 45-day waiting period before you can retest.

That structure makes a first-attempt pass more valuable than it might seem. Beyond the fee, the 45-day wait plus processing time can push your credential well out, which matters if you are tied to a job offer or a program deadline. CCI's published processing estimates also vary across its own pages, from up to 15 business days to a dated 2025 notice citing 30 to 45 business days, so do not plan around a single turnaround. For the full financial picture, see RCS certification cost.

Turning the Data Into a Prep Plan

The only prep principle that follows directly from the data is to spend time in proportion to domain weight, and to make sure no domain is neglected. A sample sequence for a candidate with several weeks to prepare might look like this:

After You Pass: Validity and Renewal

Earning the credential is the start of a maintenance cycle. Initial validity runs 9 to 12 months depending on the quarter in which you earn it. The first renewal costs USD 165 plus Code of Ethics compliance, with no continuing education units required. After that, renewal occurs every three years for USD 165 plus ethics compliance and 36 CEUs, at least 30 of them cardiovascular-related.

CCI's own pages disagree on the remaining credits: the dedicated CEU page and FAQ say they must be medical-related, while the renewal and credential pages say any topic. Planning around approved medical-related credits is the conservative interpretation. CCI uses an audit model, so keep your records through the following triennial cycle. Passing a CCI examination can also satisfy the triennial requirement at the full examination fee.
