MOC > Radiation Oncology


Radiation Oncology




Diplomates who hold TIME-LIMITED certificates, and those with CONTINUOUS certificates issued in 2012 and thereafter (with no "valid-through" dates), are automatically enrolled in the MOC program when they attain initial certification, and may start participating immediately.

Diplomates who hold LIFETIME certificates must voluntarily enroll in the program to begin the MOC process. Click here for more information.

The ABR believes in the value of Maintenance of Certification. All ABR volunteers, including governors and trustees, participate in MOC.
