MADISON, Wis. (AP) – Wisconsin students’ average ACT scores were unchanged this year compared with 2012, and they remain above the national average.  The average composite score for Wisconsin students who graduated this spring was 22.1 out of 36. That’s the same as last year and above the national average of 20.9.  In Wisconsin, 71 percent of public and private school students who graduated took the test. That’s the same as last year.  Of the states where at least 50 percent of students took the test, Wisconsin’s score was tied for second highest with Iowa. Minnesota was the highest at 23. All three states have traditionally been among the highest scoring on the test.   The results were released Wednesday by the independent nonprofit ACT.
