New data from the U.S. Department of Education show that 86 percent of Illinois students graduate from high school. That's the 20th-highest graduation rate in the country.
The department said Tuesday that the 82.3 percent national graduation rate for the 2013-14 school year was the highest recorded since it started using a new, uniform measure in 2010.
That still means nearly one in five students leaves high school without a diploma.
Education Secretary Arne Duncan praised the improvement but said too many students still drop out.
In Illinois, 90.1 percent of white students graduate. The numbers are 77.2 percent for black students and 81.3 percent for Hispanic students.
Iowa's 90.5 percent overall graduation rate was the country's highest. The District of Columbia had the lowest, at 61.4 percent.
