Persis Yu is an attorney with the National Consumer Law Center. Last March, Yu requested documents describing the incentives and bonuses built into the contracts of private companies the Department of Education hires to collect student loan debt. The documents she received were redacted to the point of being useless, Yu said. After appealing the redactions, the NCLC never heard back from DOE. Earlier this month, the NCLC filed a suit against the department for the documents.
