In her own speech to the Higher Learning Commission’s members on Sunday, Sylvia Manning, the group’s president, cited several signs that the new administration seemed willing to delve into territory that not long ago would have been viewed as off-limits to federal intrusion. Among them: A recently published “draft” of a guide to accreditation that many accrediting officials believe is overly prescriptive. A just-completed round of negotiations over proposed rules that deal with the definition of a “credit hour” and other issues that touch on academic quality -- areas that have historically been the province of colleges and their faculties. And, of special relevance for the Higher Learning Commission, a trio of critical letters from the Education Department’s inspector general challenging the association’s policies and those of two other regional accreditors on key matters -- and in North Central’s case, questioning its continued viability. With that stroke, Manning noted, the department’s newfound activism “has come to the doorstep, or into the living room, of HLC.”
