TOPEKA, Kan. (AP) — Students at public universities in Kansas will pay as much as 6.9 percent more for tuition this fall. The Kansas Board of Regents has approved tuition increases proposed by officials of the six public universities and the University of Kansas Medical Center. For undergraduates from Kansas, increases will range from 2.9 percent at Fort Hays State University to 6.2 percent at Emporia State. The biggest increase will be 6.9 percent for newly-enrolling, out-of-state, undergraduates at the University of Kansas. Fort Hays State sought no increase for out-of-state undergraduates. The increases are expected to raise an additional $31 million in the next academic year. Officials of the institutions said the money will cover higher operating costs and extra pay for employees.
