Your school may have its own loan repayment program. The school-specific programs vary greatly from school to school, but many barely make a dent for most people. For instance, I think my school only gave $5000 a year for loan payments, and if you are married, it's much harder to qualify. You should go to your school's financial aid department or find out who does exit interviews for loan before graduation. They will have the most info on if your school has a LRAP program, and the details.
There will be a federal program available in the next year or so for public interest employees. It wasn't available right after graduation this year, but it may be in effect next year; I can't remember for sure. I *think* the terms require 10 years of public service, but I don't think it has to be consecutive (could be wrong about that). You must make loan payments during the time you're working, but after you reach the 10 years of service, the remaining balance of your *federal* loans are forgiven. Working as an ADA would qualify under this program as public service. Again, your financial advisor or someone at your school will know more, and I'm sure you can find more info on the web.
As for private loans, I don't know of any loan forgiveness programs, but it may vary by lenders. I'd speak with your lender for what options they might have available.
As for repayment plans, federal loans have different repayment options. IIRC, you can either pay a fixed rate every month (standard), or graduated (pay very little now, and payments increase as time goes on), and income based (calculated by some formula). Private lenders usually have similar options.
Bottom line, check with your lender(s) to assess your options, and speak with someone at your school about any available school programs.
