launched WGU Nevada, the sixth state-based WGU. The subsidiaries of WGU share the same academic model, faculty, services, accreditation, tuition, and curricula as WGU and were established to give official state endorsement and increased name recognition to WGU in those states, as well as qualifying students of those affiliates for state-based aid. WGU does not maintain physical campuses for these institutions. As of December 31, 2020, the university had 129,169 currently enrolled students and more than 214,194 people had graduated from the institution. The median age of WGU students is 37. 2017 U.S. Department of Education financial aid eligibility audit An audit by the Department of Education's Office of Inspector General, released on September 21, 2017, "concluded that Western Governors University did not comply with the institutional eligibility requirement that limits the percentage of regular students who may enroll in correspondence courses" and that "at least 69 of the 102 courses were not designed to offer regular and substantive interaction with an instructor and, therefore, did not meet the regulatory definition of distance education."

He noted that the Inspector General
