When and why did the MOC exam change from an open book exam to a computer-based exam?
In 2006, in response to requirements set forth by the American Board of Medical Specialties (ABMS), the ABPMR transitioned to a closed-book, computer-based exam administered through Pearson VUE testing centers nationwide. The pass rate for the closed-book exam, shown to be greater than 95%, is extremely similar to that of the open-book exam.
