In 1952, the Brothers turned the school's operation over to the diocese of Winona, and Cotter became co-educational, combining with Cathedral Girls` High School. In 2021 Cotter transitioned to serve students from 16 months through Grade 12. Through its many changes in the past 110-plus years, Cotter has never wavered in its motto, Vertitam Vereantur - "Let them Revere the Truth," and upholds the finest traditions in Catholic education.
