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.
