<p>Does MIT give extra consideration to deferred Early Action candidates during the regular decision round, since they in effect have shown a greater desire to attend MIT?</p>
<p>And overall does applying Early Action improve the odds of getting accepted in either round?</p>
<p>Early action applicants are accepted at a higher rate than regular decision applicants, when the total number of EA admits + deferred EA admits accepted RD are considered. (Last year, 19.4% of EA applicants were admitted in the end, while 9.7% of RD applicants were admitted; numbers here</a>.)</p>
<p>You could interpret that as MIT favoring EA applicants. You could also interpret it as reflecting a stronger EA applicant pool. There is not much concrete evidence that could help you decide, but I think the second scenario is probably more likely. It's not, therefore, applying EA that makes you more likely to get into MIT, it's being the kind of student who applies early that makes you more likely to get in.</p>
<p>^^It does say in the Common Data Set that MIT "considers" interest in the school in determining whether an applicant is admitted. You could extend this to argue that an EA applicant should have an advantage even in the regular decision round because of their demonstrated strong interest in MIT.</p>
