The thing is, great students (high boards, great clinical grades) generally get great SLOEs. Because they are great students. Is it the SLOEs or the scores?
I generally believe its the SLOEs, because they reinforce what the rest of the application tells you. I think the PD survey data backs this up, as well as personal experience. I've talked with students with outstanding board scores who don't match because of low 1/3 SLOEs. I have seen many many students match with low board scores but good SLOEs. I have absolutely never seen a student not match in EM with top 1/3 or above SLOEs. Never. Not once. So to me, all of the data and my personal experience dictates that the SLOEs essentially will absolutely dictate competitiveness. But its to a point. Someone with middle 1/3 SLOEs with outstanding scores will still be competitive. Someone with middle 1/3 sloes with board failures won't. So the scores do matter. Its the SLOEs on the higher and lower ends that really seem to make up for bad scores or kill peoples chances regardless of scores.
So for people with high scores, ts really when there is a discrepancy (high boards but several low 1/3 SLOEs) that the SLOEs break the application chances. It's not common but it sometimes does happen. Why? Usually because of interpersonal issues, you see a lot of comments like "will be difficult to train" or "overbearing" on these SLOEs. Just be a normal person on rotation, don't act like you are gods gift to medicine, don't be defensive about feedback, etc. Also, don't try to sleep with someone in the department unless you are damn sure they #1 feel the say way and #2 aren't going to rat you out for trying to sexually harass them in the work place, which I can't believe I have to say but it happens. Have common sense, be normal, and if you are a high scoring, great grades student, you are going to be just fine.
