One of many positive features of our new Online Longitudinal Assessment (OLA) is its ability to immediately tell a diplomate whether he or she answered a question correctly. While the majority of diagnostic radiology diplomates and subspecialties are faring well on OLA, there naturally have been incorrect responses submitted to the more than 380,000 questions issued since the system started this past January. So what happens then? Anyone who submits a wrong answer will receive a similar question several weeks later. Our analytics show that most diplomates correctly answer the second question. This suggests that participants are noting the rationale feedback and possibly seeking out OLA references to learn more before receiving the next question in that topic area. As is the case with all our exams, OLA questions are written by professionals from the field. We work with more than 1,000 volunteers each year to ensure our content is relevant to the many disciplines it covers. Interventional radiology, medical physics, and radiation oncology diplomates will start OLA in January. They will have an opportunity to try the system later this year before it goes live. We will schedule interactive webinars before and after OLA rolls out for those fields.
