The RISE is in early May. The scores do not impact fellowship chances. The test is simply a way to gauge your progress, as Global said. However, I wonder how good of a gauge it really is. I scored at 4th year level for forensics without having had any forensics except for a month in medical school. And I know residents who have scored better in 3rd year than in 4th or 5th year. Also, the program directors only see scores from subjects in which you have had rotations (you have to fill out a survey at the beginning to indicate which rotations you've had). The scores for areas in which you haven't rotated don't count in the final score that the director sees. I don't think it's a great predictor for how you will do on boards. It is a good way to see where you are and what you need to improve on, though.
