Middle tier schools that are more selective than you expected

I’d love to chime in on this thread since many of our high achieving kids choose OSU, but I have to ask…how do you all know who is in the top x% of your kids’ classes? Other than a general sense of who has a high GPA from awards nights (honor roll lists published in the paper, NHS and Cum Laude induction, etc), I have absolutely no idea what rank was for any of these kids. Do some schools publish that or do you all discuss it or what?
