More than half of the students who enroll in for-profit colleges—many of them veterans, single mothers, and other low- and middle-income people aiming for jobs like medical technician, diesel mechanic or software coder—drop out within about four months. Many of these colleges have been caught using deceptive advertising and misleading prospective students about program costs and job placement rates. Although the for-profits promise that their programs are affordable, the real cost can be nearly double that of Harvard or Stanford. But the quality of the programs are often weak, so even students who manage to graduate often struggle to find jobs beyond the Office Depot shifts they previously held. The US Department of Education recently reported that 72 percent of the for-profit college programs it analyzed produced graduates who, on average, earned less than high school dropouts.
