Looking for a way to enhance admission odds? Here's a list of schools with early decision admission rates that are at least twice as high as their regular decision admission rates.  

Because Early Decision is a binding commitment, it only makes sense if you're a competitive applicant, affordability isn't an issue, and you're absolutely certain it's the school for you. But as the list shows, there can be a meaningful advantage in applying this way if you are.  For example, at Swarthmore College, over half of the incoming class is admitted through Early Decision, and the admission rate is 34% vs. 11% for those who applied via regular decision.  That's a difference too big to ignore.
