Notre Dame High School of Acadia Parish began its operation as a Catholic, co-educational school for students in grades 9–12 in September 1967. It was formed by consolidating the three Catholic high schools in Acadia Parish; Saint Michael in Crowley, Saint Joseph in Rayne, and Saint Francis in Iota. At the time of consolidation it was decided that the facilities of St. Michael be used until Notre Dame could build its own facility or make some other arrangements. On January 31, 1977, the Notre Dame School Board of Directors and seven church parishes purchased proportionate shares of Notre Dame from St. Michael Parish thus giving Notre Dame a permanent home.
