MOC Landing


what is MOC?


Maintenance of Certification (MOC) is for ABR-certified diplomates who are required to participate in order to maintain certification, or for lifetime certificate holders who voluntarily enroll to participate.

Diplomates who hold TIME-LIMITED certificates, or CONTINUOUS CERTIFICATES issued in 2012 or 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 American Board of Radiology has a history of ensuring the excellence of the professionals who practice in our field. As clinical applications, technologies, and methodologies continue to expand and develop, we recognize that lifelong learning is critical to ensure that new information and knowledge are incorporated into routine clinical practice. All ABR trustees participate in ABR-MOC.


Maintenance of Certification is an integral part of the quality movement in healthcare. Patients, your physician peers, and your colleagues all value MOC because it demonstrates your support for continuous quality improvement, professional development, and quality patient care.

The MOC program evaluates, on a continuous basis, the SIX ESSENTIAL COMPETENCIES as defined by the Accreditation Council on Graduate Medical education (ACGME) and the American Board of Medical Specialties (ABMS):

Medical knowledge
Patient care and procedural skills
Interpersonal and communication skills
Practice-based learning and improvement
Systems-based practice

MOC utilizes FOUR PARTS to evaluate the six competencies:

Part 1: Professional Standing
Part 2: Lifelong Learning and Self-Assessment
Part 3: Cognitive Expertise
Part 4: Practice Quality Improvement (PQI)

Requirements for competencies and the four parts of MOC depend on your practice area. For more detailed information, check the menu at the upper right for your area of interest.

The MOC Continuous Certification Policy also provides detailed guidelines for evaluating acceptable participation.
