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 certified and registered.

  • We don’t display credentials of people who recently took examinations until the score reports are final.
  • R.T.s who have a sanctioned status are not displayed here; search for them on our Sanctioned List.

ARRT no longer issues paper credential cards. Use one of the options below to verify status instead.

If you can’t find a listing, that person may have requested exclusion from the online directory. Try using the Request Verification on ARRT Letterhead tool.
