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, including those:
    • who are on Continuing Education (CE) probation;
    • who have a sanctioned status. 
  • People who are ineligible for certification and registration because of an ethics sanction.

Note: ARRT no longer issues annual seals. Use one of the options below to verify status instead.

Search Online Directory

Enter at least a few characters of the person’s first and last names. You will be able to view results with an option to print a copy of the verification.
