I get your point, and understand, its not an "eligibility" thing. The SLOE doesn't require proof that you are a fourth year for someone to download the form and have someone fill it out. The hospital janitor could download a SLOE and fill it out for a nurse. There's no magic key in obtaining the form. The bigger point is the "spirit" of the SLOE, who it is meant for (fourth years) and who it is meant to be filled out by (faculty at EM residencies). I've seen tons of SLOEs from people who aren't faculty at residencies. I've seen SLOEs on many 3rd years, sometimes interns, I've seen SLOEs from research rotations (I have NO IDEA why that is valid, since its a clinical evaluation), US rotations, etc. I've seen SLOEs from people who didn't even rotate at a place, but just showed up at conference... Again, there's a difference between "can you get a SLOE" and "should you get a SLOE". Some are going to be far more valid and informative than others, that is for sure.
My point wasn't to say that you CAN'T get a SLOE, because you absolutely may be able to get someone to write you one. It's more what places will consider a valid evaluation. Because once you graduate, you aren't a student anymore, you are a physician. Which means, you can't just set up "rotations" anymore. You aren't a student, you are a doctor, a doctor without malpractice insurance. At best you'd be able to shadow, and some places won't even let physicians shadow. You are VERY unlikely to be able to secure a rotation as a physician who isn't a resident. And without being able to actually rotate somewhere, I'm not sure how you can get a valid evaluation of your performance.
