A recent report by the College Board found students at for-profit colleges graduated with significantly more debt than their counterparts at public and private non-profit schools. President Obama recently overhauled the federal student loan program, changing the landscape for college lenders. Now Congress is considering ways to increase oversight of these for-profit colleges, which receive significant amounts of federal financial aid.

We interview Frontline correspondent Martin Smith, who investigated the rise of for-profit universities that cater to non-traditional students, and the efforts to regulate this booming industry. Smith worked on a new documentary produced by our partner WGBH. “College, Inc.” will be broadcast on PBS tonight; you can watch an excerpt below.
