The American Registry of Radiologic Technologists (ARRT*) has implemented a system of Structured Education and Continuing Qualification Requirements (CQR). If you were certified as a Radiologic Technologist before January 1, 2011, the new requirements will not apply to you. However, technologists who first earned their certificate on or after this date have a license that is time-limited to 10 years. Renewing certification for an additional 10 years requires completion of the CQR process. Also, moving forward as of now, R.T.’s who pursue additional credentials using the ARRT's* postprimary pathwaywill need CE credits based on specific subjects. This is known as structured education.
