The new figures show Ohio's high school class of 2012 had a composite score of 21.8 in the subjects of English, Reading, Mathematics and Science.
The score, measured on a scale of 1 to 36, is unchanged from 2011. The average is calculated from the 71 percent of Ohio students who took the exam, a jump from 69 percent in 2011. ACT officials consider Ohio one of several states aggressively pushing to improve teaching in math and science. The state's scores on both were above the national average. The ACT exam measures a high school student's readiness for college-level work. This year's national average was 21.1.
