<p>Do colleges take the highest ACT subscores from different administrations to arrive at a higher composite, in the same way that they take the highest SAT subscores?</p>
<p>Of the schools my D has looked at atttending, very few do. It has been stated by me and others that WashU, Michigan, Hendrix, and possibly Centre do allow mix and match scores. (I have recently learned that some schools call this a "super score".) All four of those schools are in the Midwest or South. I know of no other region that allows this.</p>
<p>I read that University of Chicago does.</p>
