LINCOLN, Neb. (AP) — This year’s Nebraska high school graduates scored slightly lower on the ACT exam than those who graduated in 2015, but the drop is nowhere close to the plunge the state could see in the future.

A report released by the ACT organization Wednesday shows that the statewide average composite score for the Class of 2016 was 21.4, down from 21.5 the previous year.

Nebraska Commissioner of Education Matt Blomstedt attributed the dip to “natural variability.”

The state could see larger drops after the Nebraska Department of Education moves forward on lawmakers’ plan for all high school juniors to take either the SAT or ACT beginning this school year. Blomstedt said he’d recommend which test he prefers to the State Board of Education next week.

In 2015 and 2016, 88 percent of Nebraska high school graduates took the ACT.
