UPDATE (1:05 p.m.): The NCAA enforcement staff believes UNC has shown a lack of institutional control, the highest offense the NCAA can issue.
The NCAA has alleged several level one violations, which "seriously undermine or threaten the integrity of the NCAA collegiate model."
The report names former faculty members Jan Boxill, Deborah Crowder and Julius Nyang'oro as having engaged in "unethical conduct."
Nyang'oro and Crowder refused to be interviewed for the NCAA investigation.
The notice of allegations states that UNC did not monitor Boxill's activities, representing a lack of institutional control.
The NCAA cites a history of level one and two violations, including improper academic help and illegal benefits given to student-athletes in 2012 and UNC's first NCAA violation in 1961.
UNC released a 59-page notice of allegations on Thursday June 4.
