Online Longitudinal Assessment (OLA) questions are written and reviewed by your peers. These volunteers’ mission is to create content based on “walking-around knowledge,” questions based on work performed during a routine day with value in patient care.
One question raised about Online Longitudinal Assessment (OLA) is, “When will I know how I’m doing?” If you’re a diagnostic radiology diplomate or one with a DR subspecialty certificate who’s regularly participating, you’ll see your progress on your OLA dashboard before the end of the year.
