CHEYENNE, Wyo. (AP) — ACT scores across Wyoming are down for the Class of 2018.

Wyoming Department of Education communications director Kari Eakins says the 20 earned by Wyoming's Class of 2018 is down from the 20.2 earned in 2017.

A composite score is the average of scores earned in the four core areas — English, math, reading and science.

The national average composite score earned by the class was 20.8, down from the 21 earned in 2017.

In addition to a lower average composite score, national scores in all four areas decreased for the Class of 2018.

Wyoming is one of 19 states in which all juniors are required to take the ACT. Wyoming's Class of 2018 earned an average composite of 20, which is the sixth highest score obtained among the 19 states.
