Legacy for College

<p>I have always wondered about different weights schools give for being a legacy (talking only parents matriculated-- not 5th generation or anything). Are there any prestigious schools known for weighing legacy status more than their peers? Any that hardly factor it into admissions (I've heard that Caltech is the latter)?</p>

<p>I'm merely curious as to what schools are most notorious for giving legacies preferential treatment.</p>
