Do some college not like certain high schools?

<p>I think it’s less about not liking a high school or turning down admission and more about being unfamiliar with it. Our high school in Northern California (which is ranked approx. 200 of public HS by US News) typically has 5+ kids attending U of M every year. Michigan knows our high school, the kids do well and pay the out of state fees. Our high school always does well with Stanford too (anecdotally most admits are legacies), but almost never gets a kid into Georgetown or Notre Dame. Do those colleges dislike the our high school? I say doubtful. I just think there’s only so many slots for California and they don’t know our high school. We’re told (no proof) the our local parochial schools get many more admits Georgetown and Notre Dame. If true, is that because they like Catholic/Jesuit kids better or the kids from those schools do well and therefore they have an established base. I think it’s the latter. Who knows. </p>
