<p>What happens if you apply early decision to a school and get in, but you don't withdraw your applications, as agreed under the early decision contract? I mean, I already withdrew all of my applications, but I was just curious what would happen if you didn't...?</p>
<p>Some schools share information among themselves regarding ED admits, and are rumored to revoke those that they discover didn’t hold their end of the agreement.</p>
<p>Run the risk of being blackballed when your ED school finds out and shares your duplicity with other schools, and, minimally, you incur bad karma.</p>
<p>Advice: do the right thing. It may become a habit.</p>
<p>ED schools share their applicant list with other colleges. If a student has applied to college X ED, and to College Y ED, EA, or RD, and College Y learns of the ED application to College X, both schools will deny the applicant. </p>
<p>If College X has already accepted the student ED, and learns from College Y of an open file, College X will rescind the admission offer.</p>
<p>Colleges with ED applicants do share that information broadly. The precise mechanism… I don’t know. I do believe that FAFSA lists all the schools to which an applicant has sent FAFSA with all the other colleges to which applicant has sent FAFSA.</p>
