Tuition jumped by 5.2 percent on average at public four-year colleges and universities and by 4.6 percent at community colleges, according to data released Wednesday by the State Council on Higher Education for Virginia. According to Kirsten Nelson, a spokeswoman for the state council, also known as SCHEV, tuition rose in part because universities did not have a clear picture of how much money they would receive from the state because of the General Assembly budget impasse.
