Why is the early decision acceptance rate LOWER than the normal decision?

<p>The school in question is Cal Poly SLO, which I applied early decision to a while back. It turns out that the early decision acceptance rate is lower than the normal decisions rate. Whats the point in applying to it than for me? That is my choice school and there is a greater chance that I will be denied because I've said to them I want to go to your school, where is the logic in that?
My GPA and test scores are both slightly above the admitted averages for last year, and they much higher than the admitted and attending rates. Does anybody know why this is true for this school?</p>

<p>I dont knw anything specific, but some schools cap the number of students it will accept EA/ED, so as the volume increases the acceptance rate will decrease. Don’t they roll over any qualfied applicants into the RD pool? In which case, it is still worth doing.</p>

<p>For SLO, no one is denied admission during Early Decision; you will either be admitted or deferred to regular decision; thus you do not have a greater risk of being denied admission. Stated purpose is to capture highest quality students, top 5% to 10% of class with high test scores. Unlike other colleges, SLO does not use ED to assure capturing some specific percentage of its class. Moreover, it is not really an ED program. When you get your notice of admission you need to respond with acceptance by mid-Jan. If you don’t, your admission is simply withdrawn and otherwise there is no penalty – in other words, it is not really binding and is more like an Early Action program but requires you to respond quickly and choose to be bound after learning decision.</p>

<p>They don’t determine applications based on percent in class though. I am like 13% in my class, but my school is ranked very highly in the state and the nation… That shouldn’t impact my chances right?</p>
