Physicians are increasingly choosing the Longitudinal Knowledge Assessment (LKA) over the traditional, 10-year Maintenance of Certification (MOC) exam, according to the American Board of Internal Medicine (ABIM).

Participants have noted in particular the flexibility the LKA offers as well as the ability to learn as they go. In an effort to best reflect what physicians see on a daily basis, the ABIM announced last year it was developing five new focused LKAs in three specialty areas.
