I heard that USC doesn't offer anything else than loans for the OT program (with exception to merit based scholarships, which I already applied for). I hope you're right, though...I guess we will wait and see! I once talked to a USC OT alumni, and she said that she regretted going to USC, and that she is super stressed by having $100,000 in loans.
Depending on what setting you are looking at going into there is always the public service forgiveness program. You make income based payments for 10 years and the remainder of the debt is forgiven. A lot of OT work would qualify for the program, whether it's in schools or a non-profit hospital setting. My girlfriend is a school psych with considerable debt from her masters program and is participating in the forgiveness program. I don't know that I will ever pay off the debt that I am sure to come out of school with, but I know that I will be able to make enough money that even with a monthly payment I will be ahead of where I am now. I will also be much more satisfied with going to work every day, and that you can't really put a price on that.
