Governor Bill Haslam says he wants to put Tennessee on a path to improve college graduation rates from 32 percent to 55 percent by 2025. To help he has appointed a higher education adviser, Randy Boyd is chairman of a wireless radio company and will now join a working group to look for ways to accomplish this goal working full time with no pay. The governor dubbed it the iron triangle, which deals with the affordability, access and quality of public colleges and universities. A panel will consist of the governor and representatives of the Tennessee Higher Education Commission, Tennessee Board of Regents and the University of Tennessee. (bg)
