St. Mary's Central High School is North Dakota's largest and oldest Catholic high school, with a rich history of educational excellence in the Bismarck-Mandan community.
In 1878, four sisters from the convent of St. Benedict in St.
Joseph, Minnesota, arrived in Bismarck to staff what was then the St.
Mary's Academy and Boarding School. In 1916, the first high school classes were offered and the spring of 1922 brought the first graduation at St.
Mary's High School. St. Mary's Central High School strives to promote a Christian atmosphere of learning in which all students develop themselves academically, spiritually, emotionally, socially and physically.
St. Mary's Central High School is committed to providing a foundation of faith in the Catholic tradition, and in fostering an environment in which students and staff will be free to experience the presence of Jesus Christ in their personal lives. St. Mary's is a student-centered school.
