Wisconsin's high school graduates lead the nation in test scores for the sixth year in a row among states which predominant use the ACT college admissions test.
The state Department of Public Instruction released results Tuesday that showed Wisconsin's 2002 high school graduates scored an average 22.2 out of a possible 36. It's the third consecutive year the state's graduates have done so.
The national average was 20.8.
Scores dipped slightly in English and science among the 68 percent of Wisconsin graduates who took the test. And some economic and racial disparities persisted.
Black students scored an average of just 17.2, compared with 22.5 for white students.
Students from a household with an income of $50,000 or more scored an average 22.9. Students from households of $18,000 or less scored an average 19.3.
