According to district agreements, students in the district could attend Decorah High or the high school program of Mabel-Canton Public Schools in Mabel, Minnesota. Effective July 1, 2018 the North Winneshiek district consolidated into the Decorah district. North Winneshiek School closed its doors at that time.

In 2018 the combined interim board of Decorah CSD and North Winneshiek CSD approved an agreement with Mabel-Canton schools, effective for five years, to allow students in the former North Winneshiek district boundary to attend Mabel-Canton if they choose. The agreement applies to any post-merger Decorah CSD resident who is geographically closer to Mabel than to Decorah.
