A New York City Public School teacher has joined public employees from across the country in a lawsuit against Education Secretary Betsy DeVos for her gross mismanagement of a loan forgiveness program, court papers said.

The American Federation of Teachers filed the suit in Washington, DC, on behalf of the group of public employees, including Kelly Finlaw, a city public school teacher, according to the lawsuit filed on Thursday.

The student loan-forgiveness program for public employees was initiated by Congress in 2007 “to relieve the burden of student debt for teachers, nurses, police officers, firefighters, and others who had made 120 qualifying payments on eligible student loans on a qualifying repayment plan, while working at a qualifying job.”

However, Finlaw didn’t qualify for the program because one of her two federal loans was ineligible. Even when Finlaw made 120 payments on her Federal Family Education Loan and Direct Loans, she was still denied because she had the “wrong” loans.

The filing says that the Education Department has failed “to make good on Congress’s promise, denying PSLF to applicants on arbitrary and capricious grounds.”

Furthermore, the suit claims the department has forgiven less than 1% of the borrowers applying for PSLF, the plaintiffs allege.

Finlaw’s lawyer did not immediately comment.
