The vast majority of doctoral programs specify a single date each year by which
applications must be received. The due dates typically fall somewhere between December
1 and March 1 for entry into a program the following fall. A few doctoral programs have
application deadlines falling in March or April, and due dates for master’s programs tend
to be a little later than those for doctoral programs. Very few graduate programs offer
rolling deadlines (meaning that you can send in your application any time) or both fall
and spring admissions (meaning there are two deadlines each year).
