The University of North Carolina at Chapel Hill on Friday released a report detailing academic fraud in a scandal set off by a report about inappropriate treatment received by a football player, The Raleigh News & Observer reported. The fraud involved inappropriate incidents in 50 classes, ranging from faculty members who didn't show up to unauthorized grade changes for students. Many of the questioned classes were taught by Julius Nyang’oro, former chair of the African and Afro-American Studies Department. He resigned from the chair position in September. With the release of the report, the university announced that Nyang’oro is retiring on July 1. “Professor Nyang’oro offered to retire, and we agreed that was in the best interest of the department, the college and the university,” said Nancy Davis, associate vice chancellor for university relations.
