Her charges are part of a federal lawsuit filed by seven former employees against Harris and its parent company, Premier Education Group, which owns more than two dozen trade schools and community colleges operating under several names in 10 states. The suit contends that while charging more than $10,000 for programs lasting less than a year, school officials routinely misled students about their career prospects, and falsified records to enroll them and keep them enrolled, so that government grant and loan dollars would keep flowing.

Though they vary widely in quality, for-profit schools have drawn scrutiny in recent years for aggressive recruiting, high prices, low graduation rates and heavy borrowing by students who often have poor job prospects afterward. They have been a particular target of overhaul efforts by the Obama administration. Much of the attention has gone to a handful of large, visible national chains, like the University of Phoenix, DeVry University and Corinthian Colleges, that are publicly traded. But like Premier, which had 17,000 students in 2012, most are privately owned and receive far less scrutiny.

In a separate case in New Jersey, dozens of former Harris students say that the school lied about what professional certifications they would qualify for after completing their courses; some were given a brochure saying they could sit for a dental assistant certification exam — an exam that had not been offered for years. Premier settled a similar case a few years ago before it went to trial.

The former employees’ federal suit also charges that the school enrolled people who should not have been in its programs — like a student enrolled for massage therapy, though he had been convicted of a sex crime, which would prevent him from being licensed. They say the schools enrolled students who had not graduated from high school, though their programs required it, including some who presented diplomas from known fraudulent “diploma mills.”

The company’s lawyers and executives flatly denied many of the charges, and said others, like phony diplomas, reflected only isolated instances resulting from having a hard-to-serve clientele.
