CASPER, Wyo. (AP) — Northern Arapaho schools are looking for another school superintendent.

Fremont County District 38 superintendent Jonathan Braack resigned last week after just over a year on the job. The Associated Press said it's the fourth change in superintendents in five years.

Braack's contract ends in June. He said it was time for his family to move on.

The station was unable to reach school board members for comment on Braack's departure.

In 2011, the district's Arapahoe School started federally-mandated improvement efforts after failing to make academic progress for a number of years. Last year, the school reached the progress benchmarks for the first time.
