Faculty and staff (along with their immediate families) receive remission, which equates to no class fees and 20% off classroom accessories ...including books. I went to school under this program. They still have books, a smaller portion of their student fees (all general fees) and room/board to pay for. If am not mistaken, because of the number of schools abusing I-AA scholarships (aka Herdgate), the NCAA no longer allows scholarships to be split beyond 2 parts (half class and half room & board). They way to get partial is to live at home and have the school pay for the classes, or be smart enough to get academic scholarship then take your partial for room & board. However, once you are are playing, a player really wants to live on campus and hopes for a full ride. Of course, to truly compete against our MAC brothers, we have to offer full rides.
Although you would be surprised how many IA/FBS schools do not offer as much as we do. The difference being if the FBS school offers as much as single dollar in public scholarship to an athlete (at least in most sports, including football) it counts as a full scholarship.
