Art schools do not pay
The for-profit Art Institutes programs that failed the federal test trained students in fields including commercial photography, video production, radio broadcasting, culinary arts, interior decorating and video game design. Other programs that crop up frequently on the failing list include cosmetology and barbering, acupuncture and massage therapy, criminal justice studies and low-level jobs in health care fields.
What these programs have in common is a combination of marketing appeal to young people -- design video games for a living! -- and little or no outside pressure to ensure that the education is both of high quality and leads to jobs that pay enough to finance the cost of student loans. Sure, there are good programs in all of these fields, including some offered by for-profit schools. But it can be very hard for the average consumer to know the difference beforehand.
