It was formed in 1967 by consolidating the three Catholic high schools in Acadia Parish; St. Michael of Crowley, St. Joseph of Rayne, and St. Francis of Iota.

Preceding the consolidation, committees under the direction of Father Robert Sibille, composed of faculty members and students from all three schools, met and selected possible uniforms, school colors, mascots, emblems and size.

The Catholic Church parishes actively participating in the government of the school are: St. Michael, Crowley; St. Joseph, Rayne; St. Francis, Iota; Immaculate Heart of Mary, Crowley; St. Lawrence, Mowata; St. Leo IV, Roberts Cove; St. John the Baptist, Lyons Point; and Immaculate Conception, Morse.

Mary, the Mother of Christ is the patroness of the school, and her statue stands in the center of the campus.

The Notre Dame football program has won six state championships in 1973, 1976, 2000, 2009, 2015, and 2018.
