>> reporter: the problem is that delinquent student loans are growing, passing late credit card payments for the first time and federal law requires schools to collect and sometimes sue. unlike most forms of debt, you can't get out of a student loan , not even by declaring bankruptcy, but with delinquencies rising and budgets shrinking, lenders and colleges are getting more aggressive about collecting, including taking their alumni to court. we found cases filed by yale and the university of pennsylvania which filed some two dozen suits just last year for bad loans and unpaid tuition, a 35% jump from the year before. the university has declined to comment. graff hopes his case starts a dialogue.

>> reporter: it's a conversation colleges are willing to have, but they also want their money. for "today," scott cohn, nbc news, philadelphia.
