It's rare and almost unheard of to get a full ride to PT school, but despite common belief there are some programs that offer some scholarship money. They are just very hard to get being that the programs are competitive and hard to get into as it is. Drexel offers up to $60 or 65k in scholarship (over 2.5 yrs), Thomas Jefferson offers scholarships, and Delaware does as well. These are only the ones I know of based on personal experience, I'm sure there are plenty more.
