<p>From my experience with my school's admissions 2010 (I live in California), it went something like this:</p>
<p>Stanford SCEA: ~30+ applied, 4 accepted (1 recruit), 2 deferred, the rest rejected
Stanford RA: ~20+ applied, 2 accepted from RA pool, 1 deferree was accepted (other was rejected), the rest were rejected</p>
<p>Yale SCEA: ~6 applied, 1 accepted, 0 rejected, the rest were deferred
Yale RA: ~11+ applied, 1 accepted from RA pool, all deferrees were rejected (6), the rest were rejected</p>
<p>Harvard SCEA: ~4+ applied, 0 accepted, 0 rejected, all deferred (4)
Harvard RA: ~6+ applied, 3 accepted from RA pool, 0 deferrees accepted, 3 waitlisted (2 deferrees, 1 RA), rest were rejected </p>
<p>I won't list out Princeton, cuz they hate us. Suffice it say that no one was accepted to Princeton from our school.</p>
<p>So just from my school, it seems to me that Stanford really uses the rejection frequently in SCEA. They only defer those who actually have chances. Another thing to note is that Stanford accepted those who had KILLER essays. I mean it. We had three kids who had respective SAT scores of 2400, 2390, and 2350, and were all rejected SCEA. They also had arguably better EC's than the ones who were accepted (except for 2 of them). I read the accepted students' essays, and they too believe that's what put them over the top. Stanford doesn't have an interview, so it really needs to see your personality come through in your essays and recommendations, etc.</p>
<p>Yale and Harvard both seem big on deferring applicants. Trust me, those that were deferred weren't that great. NONE of them were accepted RA...</p>
<p>Oh if you want the matriculations...5/7 are going to Stanford, 0/2 Yale, 3/3 Harvard</p>
