How to Verify a Radiologist Assistant Credential
Radiologist assistants (RAs) are advanced-practice radiologic technologists who work under radiologist supervision to perform expanded clinical functions. The credential landscape involves two certifying bodies — ARRT and ARCPA — and state-level authorization requirements that vary significantly. Here is how to verify RA credentials correctly.
Quick answer
The two recognized radiologist assistant credentials are R.R.A. (Registered Radiologist Assistant) from ARRT and RRA (Radiologist Assistant) from ARCPA. Verify ARRT credentials at arrt.org and ARCPA credentials at arcpa.org. Also confirm that the candidate holds the underlying ARRT R.T. credential and any state-specific authorization required for expanded RA practice.
Radiologist assistant vs. radiologic technologist
The distinction between a radiologic technologist (RT) and a radiologist assistant (RA) is important for credential verification:
| Role | Credential | Scope |
|---|---|---|
| Radiologic Technologist | R.T.(R) or specialty ARRT credentials | Imaging procedures; does not independently assess or perform fluoroscopic, interventional, or advanced clinical functions |
| Radiologist Assistant | R.R.A. (ARRT) or RRA (ARCPA) | Expanded clinical role under radiologist supervision: patient assessment, IV contrast administration, fluoroscopic procedures, image evaluation guidance, and certain interventional assistance |
An RA credential requires the underlying R.T. credential as a prerequisite. Verify both the base ARRT R.T. credential and the RA-specific credential.
ARRT R.R.A. credential verification
The American Registry of Radiologic Technologists (ARRT) administers the R.R.A. (Registered Radiologist Assistant) credential. Eligibility requires an active ARRT R.T.(R) credential and completion of an ARRT-approved radiologist assistant program.
Verify ARRT credentials at: arrt.org → Verify Credentials (search by name or registration number). The ARRT verification portal shows all credentials held by the registrant, including both the base R.T. credential and the R.R.A. advanced credential.
ARRT credentials require continuing education (CE) for renewal. ARRT credentials operate on a biennial (2-year) renewal cycle requiring 24 CE credits. Confirm the CE cycle is current and the R.R.A. is in Active standing.
ARCPA credential verification
The American Registry of Radiologist Assistants (ARCPA) issues a separate Radiologist Assistant (RRA) credential. ARCPA and ARRT operate independent credentialing pathways; the credentials are not interchangeable, though both are nationally recognized.
Verify ARCPA credentials at: arcpa.org → Verify a Credential. The ARCPA portal confirms credential status and expiration. Like ARRT, ARCPA requires continuing education for renewal.
State authorization requirements
RA practice scope is not uniformly authorized across states. Some states explicitly define and license radiologist assistant practice; others operate under general radiologic technology licensing that may or may not address RA expanded scope. A few states have not yet adopted RA practice authorization.
When verifying RA credentials for a specific state, confirm:
- Whether the state has specific RA practice authorization or licensing
- Whether the RA holds the required state license or registration to practice at the expanded RA scope
- Whether the supervising radiologist has formally documented the supervision arrangement as required by the state
Contact the state radiologic technology or medical imaging licensing board for current RA authorization requirements. The American Society of Radiologic Technologists (ASRT) at asrt.org maintains a state legislative tracker for RA practice acts.
Underlying ARRT R.T. credential verification
Because all radiologist assistants must first hold an ARRT R.T.(R) (or equivalent), verify the base radiologic technology credential as well as the RA-specific credential. Common base ARRT credentials to check include:
- R.T.(R): Registered Technologist in Radiography — the standard base credential required for RA eligibility
- R.T.(R)(CT): Radiography plus Computed Tomography post-primary certification
- R.T.(R)(MR): Radiography plus Magnetic Resonance Imaging post-primary certification
Verification checklist
- 1. Confirm which RA credential the candidate holds — ARRT R.R.A. or ARCPA RRA (different systems)
- 2. Verify the RA credential at the issuing organization: arrt.org or arcpa.org — confirm Active status and expiration
- 3. Verify the underlying R.T.(R) base credential at arrt.org — the base credential must also be Active
- 4. Confirm CE requirements for the current renewal cycle are satisfied
- 5. Check state RA practice authorization requirements for the state where the RA will practice
- 6. Confirm any required state radiologic technology license is active and covers the RA expanded scope
- 7. Confirm supervising radiologist documentation requirements are met per state and facility credentialing rules
Verify radiologic science program accreditation
Radiologist assistant programs and radiologic technology programs must be accredited by JRCERT (Joint Review Committee on Education in Radiologic Technology). ARRT credential eligibility requires graduation from a JRCERT-accredited program. Use VerifyED to confirm a candidate's program was properly accredited.
