ABIM MOC Updates

August 2019: ABIM to Develop Longitudinal Assessment Option

The ABIM Board of Directors has committed to evolve its program to provide a longitudinal assessment option for Maintenance of Certification (MOC), offering a self-paced pathway for physicians to acquire and demonstrate ongoing knowledge. With this new option, physicians will be able to answer a question, and receive immediate feedback as to whether it was correct or not, along with the rationale, and links to educational material. By engaging in such a pathway, physicians can assure their medical knowledge is up to date and utilize — in real-time — learning activities to address gaps. The traditional, long-form assessment will also remain an option, as some physicians have expressed a preference for a point-in-time exam taken less frequently.

While ABIM works with the community to research and develop this new option, the current MOC program, with the choice and flexibility of the Knowledge Check-In and traditional exam will remain in effect. More details will be forthcoming in the months ahead. For now, share your suggestions and questions with ABIM.

Continuing Board Certification: Vision for the Future Commission

In 2017, the American Board of Medical Specialties (ABMS) launched its Continuing Board Certification: Vision for the Future initiative to "foster an inclusive, open, collaborative, and candid dialogue across stakeholder groups." This initiative is led by a Commission includes a diverse group of physicians and patients as well as representatives from professional medical organizations, national specialty and state medical societies, hospitals and health systems, and the general public.


  1. Will the ABIM Knowledge Check-In cover the breadth of my discipline or be more targeted?
    Initially, the Knowledge Check-In will cover the breadth of nephrology, but ABIM is continuing to explore how to move to assessing a subset of knowledge relevant to practice in the future.
  2. What does "no consequences" mean for the ABIM Knowledge Check-In?
    • If a physician is successful on the Knowledge Check-In in 2018, it will count as a pass. If a physician is not successful and their exam was due in 2018 or 2019, they will have another opportunity to take it again in 2020 without a change to their certification status.
    • This rule doesn't mean physicians can skip the assessment. If a physician skips it, and his/her certification expires in 2018, his/her status will change to Not Certified.
    • In addition to meeting other certification requirements, physicians with certifications expiring in 2018 will need to take the Knowledge Check-In or pass the traditional MOC exam or they will no longer be certified.
  3. What does "open-book" mean? What can I access?
    Open book means that physicians will begin to have access to UpToDate® during the new Knowledge Check-Ins and traditional MOC exams. UpToDate is an online, evidence-based clinical decision support resource. For the 2018 Knowledge Check-Ins in internal medicine and nephrology, physicians will be able to access UpToDate directly through the exam platform. Currently, UpToDate is the only "open book" resource that is available and acceptable.
  4. On which dates are the Knowledge Check-In offered for Nephrology in 2018?
    June 7, June 9, November 1, November 6
  5. What is the fee schedule?
