Hackett Catholic Prep (formerly Hackett Catholic Central High School) was originally established in 1964 as Monsignor John R. Hackett High School in a joint agreement between the Diocese of Kalamazoo and the Society of Mary (Marianists). Originally an all-boys school, it became co-ed in 1971 with the closure of the all-girls Monsignor O'Brien High School.  Hackett Catholic Prep was originally staffed by the brothers and priests of the Society of Mary. Hackett continues to emphasize the characteristics of Marianist Education: formation in faith; integral, quality education; service, justice and peace; adaptation and change, and family spirit. Hackett Catholic Central has a current service area encompassing 20+ area school districts, providing a diverse background for the student body. Students enter the ninth grade from 30+ different junior highs and travel up to 55 miles to attend HCP. The name was changed to Hackett Catholic Prep in the summer of 2014 to more closely reflect the secular portion of the educational mission of the school. The name change does not change the focus on Catholic education.
