The short answer
CCI publishes three RCIS eligibility pathways, and your education and work history decide which one you are on — you do not choose. RCIS235 is the experience route, RCIS4 the accredited-program route, and RCIS5 the non-accredited-program route. All three additionally require a high school diploma or GED.
The three pathways in full
RCIS235 — the experience pathway
The route most working cath lab staff use: nurses, radiologic technologists, respiratory therapists, paramedics.
What CCI requires:
- Graduate of a health science certificate or degree program
- One year of full-time work experience in invasive cardiovascular technology
- 600 cardiac diagnostic or interventional procedures in their career
- High school diploma or GED
RCIS4 — the accredited-program pathway
Graduates of programmatically accredited invasive cardiovascular technology programs.
What CCI requires:
- Graduate of a programmatically accredited program in invasive cardiovascular technology
- High school diploma or GED
That is the entire requirement. No work-experience minimum, no procedure count.
RCIS5 — the non-accredited-program pathway
Graduates of non-programmatically-accredited invasive cardiovascular programs, including many hospital-based programs.
What CCI requires:
- Graduate of a non-programmatically-accredited program in invasive cardiovascular technology
- A minimum of one year of specialty training including a minimum of 800 clinical hours in the specialty
- High school diploma or GED
| Pathway | Core requirement | Work experience? | Procedure count? |
|---|---|---|---|
| RCIS235 | Health science program graduate | Yes — 1 year full-time invasive CV | Yes — 600 |
| RCIS4 | Programmatically accredited invasive CV program | No | No |
| RCIS5 | Non-accredited invasive CV program | Yes — 1 year specialty training, minimum 800 clinical hours | No |

The word that decides RCIS4 versus RCIS5
"Programmatic." What matters is programmatic accreditation of the invasive cardiovascular program specifically — not institutional accreditation of the college, which nearly every legitimate school holds.
A school can be entirely reputable, fully institutionally accredited, and still route its graduates to RCIS5 rather than RCIS4. This is the single most consequential thing on this page for anyone still choosing a program, because it changes your requirements by a full year of documented specialty training.
If you have not enrolled yet: confirm a program's programmatic accreditation status in writing, from the accrediting body, before you pay tuition. Admissions departments have been known to answer the institutional question when the programmatic one was asked — not usually from bad faith, but the distinction is easy to blur and expensive to get wrong.
The documentation requirements people underestimate
Requirements rarely disqualify people. Documentation delays them, routinely and avoidably.
If you are on RCIS235: log procedures from day one
The 600-procedure requirement is a record-keeping problem long before it is a clinical one. Most people hit the number well before they think about applying — and then have to reverse-engineer it out of old schedules and memory. Start a running log on your first shift in the lab. It costs about thirty seconds a day and saves a genuinely awful weekend later.
If you are on RCIS5: get your clinical-hour record while you are still enrolled
The 800 clinical hours are similarly a documentation problem. Ask your program director now how hours are recorded and whether you will be able to obtain that record after graduating. Tracking down a program coordinator two years after you left is far harder than asking while you are in the building.
If you are on RCIS4: get the accreditation status in writing
Your entire eligibility rests on one fact about your program. Have documentation of it rather than an assumption about it.
Does your experience count?
The RCIS235 requirement specifies work experience in invasive cardiovascular technology. Time in telemetry, echocardiography, or a non-invasive cardiology clinic is clinically valuable but is a different category for eligibility purposes.
If you are unsure whether your particular role qualifies — and hybrid roles genuinely do create grey areas — ask CCI before you apply and pay, not after. CCI is the only body that can answer that question about your specific situation, and a summary page like this one cannot.
Is there an RCIS license?
No. There is no RCIS license. RCIS is a professional certification awarded by CCI, a credentialing organization — not a state regulator. People often say "RCIS license" when they mean the credential, and the words matter here.
A license is issued by a state board and grants legal authority to practice a profession. A certification demonstrates that you met an independent knowledge standard. The RCIS is the second kind. It does not by itself permit you to perform any task; your permitted scope comes from your own license where you hold one, from state law, and from your employer's policies. That distinction is worked through properly on RCIS scope of practice.
The practical upshot is that "RCIS licensure requirements" is not a thing that exists. What exists is CCI's eligibility criteria, which is what this page covers.
How do you verify an RCIS credential?
CCI operates a public credential verification tool, so employers, recruiters, and individuals can confirm whether someone currently holds an active CCI credential. It is available through CCI's credential verification page.
Two things worth knowing about verification:
- Credentials expire. Verification shows current status, not that someone once passed. CCI renews registry-level credentials on a three-year cycle requiring 36 CEUs, of which a minimum of 30 must be cardiovascular-related. A lapsed credential is not a current one.
- Verify at the source. A certificate on a wall or a line on a resume is not verification. If you are hiring, check CCI's tool directly — it takes less time than the phone call you would otherwise make.
Verification is provided by CCI at myaccount.cci-online.org; renewal and CEU requirements per CCI's renew credentials page and CCI's continuing education page, retrieved 2026-08-15.
Eligible is not the same as ready
Meeting the requirements means CCI will let you register. It does not mean you will pass. Those are separate clocks, and treating them as one is how a capable person ends up paying a second exam fee.
Once you know your pathway: confirm current requirements with CCI directly, assemble your documentation early, then find out what the exam actually tests. The blueprint is public and heavily weighted — diagnostic procedures at 40% and interventional at 34%. Study to the weights using the RCIS study guide, and see the whole process end to end on how to get RCIS certification.

What are the requirements for the RCIS?
One of three CCI pathways plus a high school diploma or GED. RCIS235: health science program graduate, one year full-time invasive cardiovascular experience, 600 procedures. RCIS4: programmatically accredited invasive cardiovascular technology program graduate. RCIS5: non-accredited program graduate plus at least one year of specialty training including at least 800 clinical hours.
Is there an RCIS license?
No. RCIS is a certification from CCI, not a state-issued license. A license grants legal authority to practice; a certification demonstrates you met an independent standard.
How do you verify an RCIS credential?
Through CCI's public credential verification tool, which shows whether a credential is currently held and active.
Do you need a degree for the RCIS?
Not necessarily a degree, but every pathway requires formal education plus a high school diploma or GED — a health science certificate or degree program for RCIS235, or an invasive cardiovascular technology program for RCIS4 and RCIS5.
How many procedures do you need for the RCIS?
600 cardiac diagnostic or interventional procedures, but only on the RCIS235 experience pathway. RCIS4 and RCIS5 carry no procedure count.
Does telemetry or echo experience count?
The requirement specifies invasive cardiovascular technology experience. Non-invasive cardiology roles are a different category — confirm your specific role with CCI before you apply.
