If you don't get at least a 50% scholarship to Vandy, then you should look to wherever you got money. Otherwise it is simply too expensive. This of course is assuming you got money from a good school.
Graduates from Vanderbilt do tend to make more money than those from many other schools. This is partly due to the reputation, as well as the networking that goes on from day one. However, the biggest reason by far is because Vandy produces excellent audiologists. Due to the faculty and facilities, it is easier to be excellent coming out of Vandy than elsewhere. However, with a little more effort, you could also be excellent coming out of a solid state school. If you get full funding at a U. of Memphis or another comparable school, I would go there, from a purely educational perspective.
In my opinion and that of multiple Audiology professors, it is absolutely foolish to take more than 80k in debt for an Audiology degree. There are tons of ways to make money in other fields without that kind of debt. When you look at salary data and the strongest predictive variable for salary is years experience, you know that lots of debt is not a wise choice.
Do not, however, go to a crappy school (and there are lots of them) just because they cover your bills. There are schools that should not be allowed to stay open. Don't take the PC perspective of everyone is equally amazing. If you choose a bad school this April, you will pay for it the rest of your career in the form of lower pay and ******ed advancement.
In sum, if Vandy, or any expensive private school, does not give you at least 50%, take a walk. You're diploma may not be as shiny, but your brand new car will be!
