Does Dartmouth have a cap on Early Decision Admits?

No. That said, the Admissions Office typically admits about 35% of the entering class through the Early process. We want to make sure that there are ample opportunities for both our Early Decision applicants and our Regular Decision applicants and we have found over the years that the ~35% range allows us to respond favorably to a strong cohort of our ED applicants without infringing on the opportunities of our Regular applicants.
