The mission of the Catholic schools of the Diocese of Des Moines is to provide meaningful educational experiences for children/adolescents in an environment integrated by Gospel values which nurtures faith, community, prayer and service.
Therefore, we believe that Catholic schools exist to teach the traditions and doctrines of the Catholic Church and to live the Gospel message of Jesus Christ; parents are the primary educators and Catholic schools are partners with parents in the education of their children/adolescents; Catholic schools will provide a warm, caring environment where children/adolescents will be challenged to learn the essential curriculum regardless of learning rate or style; all children/adolescents in Catholic schools will learn the value of human dignity and the concepts of peace and justice to enable them to be participants in a global society.
