Verify Credentials

This directory is the primary source for verifying someone’s ARRT certification and registration status. We update it daily, listing:

  • R.T.s who are currently certified and registered 
  • R.T.s who are on Continuing Education (CE) probation
  • R.T.s who have a sanctioned status
  • People who are ineligible for certification and registration because of an ethics sanction

For people who recently took examinations, we don’t display credentials until the score results are final.

Note: ARRT no longer issues annual seals. Use this directory to verify status instead.

  • The search isn’t case sensitive. 

What to Do If Someone Isn’t Listed

If you can’t find a listing for someone, that person might not be certified and registered or might have requested exclusion from this directory.

To obtain verification for someone who isn’t listed, call 651.687.0048, ext. 8901. Be prepared to provide two personal identifiers for the individual you’re seeking to verify (e.g., the person’s ARRT identification number, Social Security number, or date of birth).

What to Do If a Listing Doesn’t Show Credentials

If the person you’re attempting to verify is listed, but their entry doesn’t display any credentials, call 651.687.0048, ext. 8580, for additional information.
