How to Verify a Radiologic Technologist License
Radiologic technologists (rad techs) perform diagnostic imaging including X-rays, CT scans, MRI, and fluoroscopy. ARRT certification is the primary national credential. Most states also require a state license. Fluoroscopy and mammography require additional endorsements.
Quick answer
Verify ARRT credentials (radiography, CT, MRI, mammography, and others) at arrt.org using the public credential verification tool. For state licensing, verify through the state radiologic technology licensing board — most states have public online lookup tools. Fluoroscopy and mammography require separate state endorsements in many states.
ARRT credentials for radiologic technologists
The American Registry of Radiologic Technologists (ARRT) is the primary national credentialing body. ARRT credentials cover primary certifications and post-primary specializations:
| ARRT Credential | Modality | Type |
|---|---|---|
| RT(R) — Radiography | General X-ray; most common entry-level rad tech credential | Primary |
| RT(CT) — Computed Tomography | CT scanning | Post-primary |
| RT(MR) — Magnetic Resonance | MRI scanning | Post-primary |
| RT(M) — Mammography | Mammographic imaging | Post-primary |
| RT(F) — Fluoroscopy | Real-time X-ray imaging; separate state permit often required | Post-primary |
| RT(VI) — Vascular Interventional | Interventional radiology procedures | Post-primary |
To verify ARRT credentials:
- Go to arrt.org and use the “Verify Credentials” public tool
- Search by name or ARRT ID number
- Confirm all credentials listed, their Active status, and expiration dates
State licensing
The majority of states license radiologic technologists. State licenses are required in addition to ARRT certification. Most states base their licensing requirements on ARRT certification but issue separate state credentials.
State licensing lookup resources
- California: Radiologic Health Branch, CA Dept. of Public Health — cdph.ca.gov
- Texas: Medical Radiologic Technologist Certification — dshs.texas.gov
- Florida: Dept. of Health, Radiologic Technology Board — flhealthsource.gov
- New York: Office of Professions — op.nysed.gov
- All states: ASRT maintains a state licensing resource at asrt.org
States without rad tech licensing
A small number of states (including Colorado, as of recent years) do not have state-level radiologic technologist licensing requirements. In those states, ARRT certification is the primary credential to verify. Check current state status with ASRT's legislative resources.
Fluoroscopy and mammography endorsements
Fluoroscopy and mammography involve additional radiation dose or specialized procedures, so many states require separate permits or endorsements beyond the general rad tech license:
- Fluoroscopy permit: California requires a separate fluoroscopy permit issued by the state. Texas and others have similar requirements. Verify through the state radiation control program
- Mammography: FDA regulations under the Mammography Quality Standards Act (MQSA) require mammography technologists to meet specific training and qualification standards — beyond ARRT RT(M) certification. Facilities must be MQSA-certified and maintain technologist qualification records
When hiring for fluoroscopy or mammography roles, confirm the relevant state permit and any MQSA qualification records in addition to ARRT certification and state license.
Red flags
- ARRT credential not found or listed as expired at arrt.org
- State license not found when the state requires licensure
- Technologist performing CT or MRI without the relevant post-primary ARRT credential
- Performing fluoroscopy in California without a state fluoroscopy permit
- Mammography technologist without MQSA qualification documentation
- ARRT credential that lists only a post-primary (CT, MRI) without an underlying primary credential — post-primary credentials require a primary first
Verification checklist
- 1. Verify all ARRT credentials at arrt.org — confirm each credential type, Active status, and expiration
- 2. Confirm ARRT credentials match the imaging modalities the technologist will perform
- 3. Verify state license with the state radiologic technology board if the state requires it
- 4. For fluoroscopy roles: confirm state fluoroscopy permit if required (California, etc.)
- 5. For mammography roles: confirm ARRT RT(M) credential and MQSA qualification documentation
Verify radiologic technology program accreditation
Radiologic technology programs are accredited by JRCERT. Use VerifyED to confirm whether a school's radiologic technology program is properly accredited.
