"The state’s commitment to higher education is what drew me here three years ago, and it’s what propelled me forward every day on the job,” Spellings said. “I will forever be honored and humbled by the opportunity to serve alongside our terrific chancellors, faculty, staff, students and our Boards of Trustees and Board of Governors."

Under President Spellings’ leadership, the university says, the UNC System capped tuition, created a national model for accountability and transparency, modernized its data systems, and shifted its focus to tackle key issues of upward mobility and economic impact in all of the state's100 counties.

“Under Margaret’s strong and capable leadership, we have worked together to achieve a lot of great things – keeping college affordable, holding ourselves and our institutions accountable, and getting the facts, data, and details we need to be world-class," says Harry Smith, Chair of the UNC Board of Governors.
