Students admitted full-time to the program usually get scholarships worth 25%-75% of tuition, with most falling in the mid-range of 50%. Two or three of the students admitted straight into the PhD receive full funding with fellowships that usually require some non-paid internship over the course of their enrollment. From what I understand its usually a semester or two and you'd set up the internship with approval of your advisor. This is part of Drew University's mission to craft public intellectuals who give back to the community. There are a few (2-3) TA positions available each semester that usually pay $1,000/semester. The workload for that position varies depending on the professor and the course. The idea behind that is to give students some experience more than provide you with a hefty paycheck.
Some caveats regarding financial aid: Because its a small school you have to take the initiative to find out what you need and when, especially when it comes to getting your loan money and deferral paperwork. Also, if you take out extra loans to pay for housing or living costs you will have to email the financial aid office about two weeks after the last drop date to request that they actually give you a check for whatever loan money is left after your costs are paid. What this usually translates into is that you will not get any money for living expenses until almost midway through the semester. So if you enroll in Drew University you will have to have some outside resources to tide you over until Mid-October and then again Mid-February.
As far as admissions, this year Drew University had the highest number of applicants it has every received. We were told during orientation it was somewhere in the 300-range. Approximately 30 or so were admitted this year and most of those students accepted. I believe the faculty are looking at
