<p>Isn’t it obvious?  Look at it from the school’s standpoint.  The purpose of grants is to meet financial need.  An outside scholarship is a resource which can be used to pay for college, reducing the need.  If a third party is willing to kick in part of that need, why shouldn’t the school reduce their need-based package?</p>
<p>I understand your desire for a comprehensive list, but the fact that someone hasn’t already done this should tell you that it’s not really practical.  As other posters have mentioned, school policies vary and the only real way to tell is to check with the specific school.</p>
<p>One example:  My D applied to 5 schools, and even among that tiny sample, we ran into 4 different policies.  One school reduces grants first, one reduces work/study first, and two reduce federal loans first.  If the scholarship exceeds that “first”, it will then be applied against one of the other elements, and this also will vary by school.  Only the fifth school allowed outside scholarships to be applied to EFC, and even then, only up to a certain amount.  After that, they would be applied to either grants, loans, or work/study (I can’t remember which).</p>
<p>So you can see that there are so many permutations of this phenomenon that it’s difficult to compile a Yes/No list.  But as a general rule, from our experience and from what I’ve read elsewhere, most schools are going to use outside scholarships to reduce some piece of the need-based aid.  Not all, but most.  </p>
<p>When my D was a senior and I found out about this issue, I told her not to waste her time applying for such scholarships.  In addition to the problem you identify, there were plenty of other things not to like.  For starters, most of them are in the $500-1000 range, nickel-and-dime stuff compared to the cost of college.  And most of them are one-year scholarships only, and available only to freshmen – what about sophomore year and up?  I asked her instead to spend that time researching schools which are known for giving good merit money for applicants with her stats.  With that strategy, she won a very nice scholarship *from the school <a href=“renewable%20–%20meaning%20that%20she%20doesn’t%20have%20to%20re-apply%20for%20it%20every%20year”>/I</a>.   This, on top of a generous need-based grant, made college possible.</p>
<p>Finally, I got some great advice which you might want to pass on to your students:  More than 95% of the scholarship dollars are awarded by the schools themselves.  Go where the money is.  ;)</p>
