The schools she went to for grad school include 1 completely unaccredited "university" as well as another that is under Federal scrutiny for financial aid fraud and is not, to my knowledge, regionally accredited (it's run by Jerry Falwell's people and does not have public Board meetings - so cannot be regionally accredited, IMO).
These schools give people nice paychecks every month (out of Federal financial aid) even if they have tuition for free (say, on some military program or because a spouse pays). If their completion rates drop below 50% (her university's completion rates are averaging around 30%), they get a red flag with the Feds.
Meantime, hundreds of thousands of Americans use this financial aid (and as everyone knows, this is the same group that defaults). If a 'college' is giving out financial aid and even if a person completes, if they cannot find a paying job and do not pay back their loans, those are 2 black marks on the college's record (can't find job, isn't paying back loan).
