Student Loan Question

I am hoping DU can help me sort through something. My husband still has student loan debt from his Doctorate. Someone told us if he taught at a public institution for 10 years it could be forgiven, is that true? He has taught for 15 years now. I cannot find anything online about it and Sallie Mae is not at all helpful, as usual. We don't have a lot left, but it would make a huge difference in our financial life if it the last 5 years of it were gone. With my health issues, and no raises it is getting pretty tight here.

I don't want to seem ungrateful, we know we have been blessed to have jobs and be able to help our elderly parents when things got tight but it just seems like we are getting squeezed even tighter than we were when we were helping pay a nursing home bill.....

Any help would be appreciated!
