While the Education Department cannot legally tell accreditors precisely how to evaluate colleges and universities, it does oversee some key requirements, and these new rules dramatically expand those requirements and the department’s authority with them.

Most notably, accreditors must now evaluate school policies on intellectual diversity, “ensuring that students are exposed to a range of viewpoints,” according to a department press release.

It’s not entirely clear how that requirement will work in practice, but opposition has been loud.

“For the first time,” Shireman says, “you will have an avenue for the federal government to go in at least to an accreditor, but through accreditors to colleges, and tell them what balance of points of view the federal government thinks they should have.”
