Nebraska's 2013 high school graduates scored higher than students nationally.
In test results released Wednesday, Nebraska's average ACT composite score was 21.5, six-tenths of a point higher than the national average of 20.9.
The highest possible ACT score is 36.
Steve Kappler is an ACT assistant vice president, and he says that because of various changes, past ACT results should not be compared to the 2013 results.
Nebraska students scored an average of 22 last year, down from 22.1 in 2011, on the test that measures college readiness. The national average was 21.1.
Eighty-four percent of Nebraska's high school graduates took the ACT this year, compared with 78 percent last year.
