About the exam. The Radiologic Technology Licensure Program is currently contracting with the ARRT for their Limited Scope Examination for State Purposes. This is not the same examination that Registered Radiologic Technologists take for their national registry. This is the national examination that is the standard for almost every state with a State Licensure Program.
