Indiana and Michigan were ahead of the national curve when it comes to the ACT exam.
This year's class of Indiana high school seniors averaged higher scores on the ACT college entrance exam than those a year earlier.
The average score for Indiana's class of 2007 was 22.0 on a 36-point scale, an improvement over last year's average of 21.7. The national average score was 21.2 for this year, up from 21.1 last year.
Indiana's average score on the ACT, which measures students' readiness for college-level work, has exceeded the national score for more than a decade.
However, only about 21 percent of Indiana's 2007 graduating class took the ACT. Nationwide, about 42 percent of students took the ACT.
More than 60 percent of Indiana students took the SAT exam, where the state's scores lag behind the national averages.
Michigan scores on the ACT college entrance exam generally were better than the national average for the 2007 high school graduating class.
The state's average composite scores for math, reading and science all top the national average. Michigan's composite average English score is the same as the national average.
Only 23 percent of nationwide test-takers had met a benchmark score that indicates readiness in a range of introductory, core college courses. Twenty-six percent of Michigan test-takers reached that benchmark in all four broad subject areas.
About 70 percent of Michigan's 2007 graduates took the test.
SAT results for the class of 2007 will be released later this month.
