<p>Single choice early actions prevents you from applying to any other school with the exception to public instate schools during the early admissions cycle.</p>
<p>By restricting such action you'd expect that it'd somehow show commitment for Yale, and thus boost chances. </p>
<p>However, on Yale's website they say it does not help chances of getting in.</p>
<p>So what's the purpose of applying SCEA if it only restricts you? Is Yale's statement false, what does SCEA actually do for you.</p>
<p>The advantage is that is you’re accepted, you have a magnificent option in your back pocket by December.</p>
<p>The disadvantage is that Yale’s SCEA rules eliminate the possibility of using your early “card” at another school where an early application offers a greater admissions boost.</p>
It allows an applicant to express a “special interest” in Yale that falls short of commitment but still excludes peer schools like Harvard, Princeton, Stanford, etc. The special interest is emphasized somewhat now that H and P have restored their early programs. This increases Yale’s ability to shape its class insofar as the SCEA admits yield at a higher rate than the RD admits. As a result the admissions office then has a better idea of who will be coming in the Fall and can use this information to shape its RD choices.</p>
