I don’t think that legacy status alone (i.e., without substantial donation dollars) is a true hook when you are talking about Ivy level schools. I’ve seen too many high achieving students at my kids’ HS who have been rejected by their parent’s Ivy League alma maters. Some of these schools (Penn and Cornell) don’t even consider legacy status except in the ED round. I also agree with what the others have said about “Ivy material.” With true admission rates at or below 5% for unhooked applicants, spending your HS years gunning for the Ivies is usually a fool’s errand.
