For-profit colleges expanded dramatically over the last two decades, with enrollment rising from around 230,000 in the early 1990s to a record 2 million in 2010. They recruited aggressively, targeting non-traditional students — usually older people who had jobs and could study only part-time. They also focused heavily on women, people of color and veterans. But after graduating, many students struggled to find jobs that were promised to them or to transfer credits to other schools, leading to massive student loan defaults. A 2010 government study found that all 15 of the for-profit colleges evaluated by undercover agents made deceptive statements to prospective students and that four of them encouraged fraudulent practices.
