Students attending for-profit colleges wind up with much higher student-loan debts, are less likely to be employed after graduation and generally earn less than similar students at public or private nonprofit schools, according to a recent paper [1] from the National Bureau of Economic Research [2], the Huffington Post reports. The study, conducted by a group of Harvard researchers, examines a bevy of federal data tracking student graduation rates, federal loan repayment rates and student success in securing jobs. The researchers ask one central question: Are for-profit colleges “nimble critters” responding to higher demand for college degrees, or “agile predators” that target low-income students with the intent of reaping profits through federal student aid dollars?
