• Exciting Announcement!

    Orchard Lake St. Mary’s Preparatory announces a new, innovative approach to learning and student development in the Fall of 2020. St. Mary’s will become the first Catholic high school in its region to operate under a co-divisional model, with boys and girls educated in a single-gender learning environment on the same campus.

     

  • What is Co-Divisional?

    This model offers a single-gender classroom experience alongside opportunities for boys and girls to engage socially, spiritually and in co-curricular activities. St. Mary’s prepares its students to excel in college and beyond by developing their abilities to think critically, work collaboratively, and succeed independently.

     

    In this culture, for the first time, both boys and girls will have all of the advantages of co-educational interaction without social pressures in the classroom. With the boys and girls in separate classrooms for the majority of their instruction, students have a choice of when and how they socialize during break times, before, and after the school day ends.

     

    Our mission and message remain the same:

     

    1. God

    2. Family

    3. St. Mary's
