How to Use the ARRT's Verify Credentials Lookup
Five steps on the ARRT's own directory, from the search to a verification on ARRT letterhead.
Open Verify Credentials
Go to the ARRT's Verify Credentials page, the official directory of the medical imaging and radiation therapy professionals it certifies and registers.
Tip: The page can ask you to tick a box that confirms you are a person before the search runs.
Verify Credentials, ARRTSearch by name
Enter at least a few characters of the technologist's first and last names, then open the technologist's result.
Tip: Print a copy of the verification from the result.
Read the credentials
The result lists each credential with its description, the Valid Thru date, the CE biennium and any CQR compliance period, beside the technologist's city, state and ZIP code.
Tip: Valid Thru is the technologist's annual renewal date, which falls on the last day of the birth month.
Check the sanctioned list
Search the ARRT's sanctioned list by name, or list everyone added in the past year or from one state. Public reprimands stay on it for one to three years; the ARRT does not publish private reprimands.
Tip: For a question about a name on the list, call 651.687.0048 and choose the option for ethics information.
Sanctioned List, ARRTVerify on ARRT letterhead
The ARRT calls the directory the primary source for verifying certification and registration status. For a verification on ARRT letterhead by download, email or fax, start a request with two of the technologist's Social Security number, date of birth and ARRT ID.

What Each Status Means
The ARRT certifies and registers a technologist only while they meet its requirements. Each meaning is the ARRT's own, and links the page behind it.
| Status | What it means |
|---|---|
| Certified and registered | The technologist meets the ARRT's requirements for certification and registration and may use the ARRT credential. ARRT Rules and Regulations |
| Discontinued | The technologist did not renew, did not meet the renewal requirements or missed the deadline for information, so the ARRT discontinued the certification and registration. Annual Renewal |
| Suspension | The certification and registration is suspended for a period of time, and the person may not use an ARRT credential for any purpose during it. Types of Sanctions |
| Revocation | The ARRT has removed the certification and registration, its most serious ethics sanction, and the person may not use an ARRT credential for a set period. Types of Sanctions |
| Denied Reinstatement | The ARRT's Ethics Committee denied the person the chance to reinstate, so they are not certified and registered. Types of Sanctions |
An ARRT credential is not a state license: in some states a technologist also needs the state's license to work, and applies to the state for it.

Technologists renew ARRT certification and registration every year for $65, whatever the number of credentials, and report continuing education every two years.
