Maintenance of Certification (MOC)


PLEASE NOTE: All diplomates participating in Maintenance of Certification (MOC), except those initially certified in 2013, 2014 and 2015, will have their first "full" annual look-back on March 2, 2016. To maintain certification, these diplomates must attest to meeting MOC requirements no later than March 1, 2016. Diplomates initially certified in 2013 or later must only attest to Part 1-medical licensure. Simplified attestation will be available on myABR beginning Monday, January 4, 2016. Diplomates should log in to myABR and affirm that MOC requirements have been met. Entering detailed data is not necessary, but diplomates should keep this information in case of an audit. Diplomates may continue to complete MOC requirements for the March 2 look-back through March 1. Questions? Contact ABR Connections at information@theabr.org or 520-519-2152.

The American Board of Radiology's Maintenance of Certification (MOC) process is designed to facilitate and document the professional development of each diplomate through its focus on the essential elements of quality care. ASTRO offers numerous opportunities for physicians and physicists to satisfy their MOC requirements through in-person meetings and online educational offerings. Explore the tabs below to see how ASTRO can help you meet your individual MOC requirements.

What should I be doing to maintain my certification?

Under the new rolling certification process that was implemented by the ABR in 2013, there will be an annual look-back that will evaluate a diplomate's participation in the three previous calendar years. To help diplomate’s adjust to the new process, the first three look-back years (2013, 2014 and 2015) will only check that a diplomate is meeting the licensure and exam requirements. The first full look-back will occur in 2016 and will review a diplomate’s participation in all four part of MOC. 

At the time of each annual look-back, you must have: 

  • An active, current, valid and unrestricted license relevant to all of your locations of practice. 
  • Completed 75 CME (at least 25 of which are SA-CME) within the three previous calendar years. (Participate in ASTRO's CME and SA-CME offerings.)
  • Passed the exam within the 10 years previous calendar years.
  • Completed one PQI project within the three previous calendar years. (Participate in ASTRO's PQI offerings.)

Where can I learn more about MOC?
