<p>Does anyone know how the following colleges treat previous SAT administrations if an applicant takes the test more than once? (like averaging? highest combined score? highest individual sectional score?)</p>
<p>Harvard
Stanford
MIT
Princeton
Yale
Cornell
Columbia
Caltech
Williams
Amherst</p>
<p>Almost all colleges will take your highest score from each section. There have been a few schools have have insisted in single sitting scores, but they are few and far between. No college is known to average test scores</p>
<p>Each of the colleges you listed take highest subscores from multiple tests, except that both Yale and Harvard have made statements that go along the lines that they consider it unwise for you to take the test more than twice. They don't actually say they hold it against you if you take it three times or more but that could be implied from what they say. </p>
<p>I am unaware of any college on the undergrad level that averages scores from multiple tests. However, for the LSAT and law school admission that is standard practice.</p>
