So there are significant implications for financial aid, across the entire university, and there are legal implications as well flowing from that. So, the immediate question is, do private schools have less leeway in tinkering with that number? I am assuming that proportionally more students receive financial aid at private schools than at government schools, given the generally higher tuition costs.
Take the University of Georgia. I believe that the HOPE scholarship program essentially pays tuition for you if you maintain some minimum academic standing and achievement through high school. I would expect that most of the students at UGA are from Georgia, and a great many (most?) are there on the HOPE scholarship. Since the taxpayers of the state are already paying the tuition costs for that chunk of the student body, there is less dependence on Pell grants and other traditional forms of financial aid. So UGA can jack up the TCoA number if desired, because it has little effect on the student body at large, but it could be a boon toward the athletics folks. Right?
