The nation's oldest black college, Cheyney University, one of Pennsylvania's 14 state-run universities, is on the verge of a financial meltdown that threatens its ability to continue operating, a state official said on Wednesday. Cheyney's student body has shrunk by two-thirds, to about 1,000, since its 1983 peak, and its four-year graduation rate is just 9 percent. A quarter of students never receive a degree, and student loan defaults are high.
