The topic of school tier is a messy one. Unless you're in a big org that's running really active recruiting efforts at the source of top tier schools, you may not have a real representative set of high tier applicants to ultimately check for differentiation. This topic also gets political and ideological really quick, but we do have some reasonably sound data that says for example that (and I'm speaking broadly here) people with MBA's from "division 1" style schools tend to annihilate (to put it lightly) lower tier MBA's in work simulation exercises involving business acumen related competencies.
