The schools have a strong incentive to enroll service members and veterans, in large part because of the “90-10 rule” created by the 1998 amendments to the Higher Education Act. Put simply, the rule says that a for-profit college must obtain at least 10 percent of its revenue from a source other than Title IV education funds, the primary source of federal student aid. Funds from Tuition Assistance and the G.I. Bill are not defined as Title IV funds, so they count toward the 10 percent requirement, just like private sources of financing.

Therein lies a problem. For every service member or veteran (or spouse or child, in the case of the post-9/11 G.I. Bill) enrolled at a for-profit college and paying with military education funds, that college can enroll nine others who are using nothing but Title IV money.

This gives for-profit colleges an incentive to see service members as nothing more than dollar signs in uniform, and to use aggressive marketing to draw them in and take out private loans, which students often need because the federal grants are insufficient to cover the full cost of tuition and related expenses.

One of the most egregious reports of questionable marketing involved a college recruiter who visited a Marine barracks at Camp Lejeune, N.C. As the PBS program “Frontline” reported, the recruiter signed up Marines with serious brain injuries. The fact that some of them couldn’t remember what courses they were taking was immaterial, as long as they signed on the dotted line.

Some for-profit colleges have also created Web sites with military-sounding names. Although they present themselves as offering unbiased advice on G.I. Bill benefits, some are using deceptive methods to bring in students.
