SPRINGFIELD, Ill. (AP) -- The Illinois State Board of Education says Illinois' high school graduating class of 2014 earned a composite score of 20.7 on the ACT.
The score on the four-subject test is slightly higher than the class of 2013's score of 20.6. The national average is 21.
Board officials say Illinois had the second-highest composite score among the 12 states that tested 100 percent of graduates, next to Utah.
This school year was the last year the ACT served as a mandatory test given to high school juniors in Illinois. The state will administer the Partnership for Assessment of Readiness for College and Careers tests in 2014-15, which are tied to the Common Core Standards.
Slightly more than 158,000 students were tested in the Class of 2014, compared to 160,066 in 2013.
