There are many examples of these schools nationwide and in Baltimore. One school, PSI Institute, had a physical location near Lexington Market and recruited students from the local foot traffic. Another, USA Training Academy, involved a door-to-door salesperson who targeted poor Baltimore neighborhoods to enroll students in a bogus home study program. Both programs came under federal scrutiny for fraudulent practices, both schools closed in the early 1990s, and both left students with loans that they could not repay for an education that they never received. Many low-income Baltimore residents are still struggling to repay these debts.
