This Monday, students attended the first classes held at Duke Kunshan University—a school that Duke has been developing and planning to open since 2009. The stretch of time in between saw many landmark occasions for both universities, as well as numerous delays, construction issues and controversy. DKU's progress is still unfolding even while programs start, as five out of six of the campus' buildings are still under construction and a master's in management studies program will begin next semester.
