The U.S. Department of Education comparable state-by-state graduation numbers show that only three states have a wider disparity between graduation rates for blacks and whites.
Ohio's graduation rate for all students was 80 percent for the 2010-11 school year, the first year in which a common calculation was used in most states.
For black students, the rate was 59 percent. For white students, it was 85 percent. For students who come from poor families, it was 65 percent.
Iowa had the top overall graduation rate, while Nevada had the lowest.
The numbers were reported by The Columbus Dispatch Wednesday.
