History. It was established on July 1, 2014, by the merger of the Armstrong–Ringsted Community School District and the Sentral Community School District. The merger passed in a June 2013  election in the Armstrong-Ringsted district by 291-42 and in Sentral by 78–18, and the approval was through a total of 86% of voters in both school districts.

Matt Berninghaus, already principal of Armstrong-Ringsted, began serving as the interim North Union superintendent and became the formal superintendent effective July 1, 2014.
