Nebraska high school students are still outscoring their peers nationally on the ACT college entrance exam, even though the results slipped from last year.

A report released Wednesday shows Nebraska students who graduated this year outpaced the national average in English, reading, mathematics and science.

Nebraska students scored an average of 22 on the test, which measures college readiness. The national average is 21.1. The highest possible ACT score is 36.

The report also shows that 78 percent of Nebraska students took the test. Nebraska was one of 18 states with a participation rate higher than 75 percent.
