The goal of the St. Mary's School board is to promote the ministry of Catholic education; the spiritual, intellectual, physical, emotional, and social development of students. The board works closely and in collaboration with the administration of St. Mary's School to assist with strategic planning, formulating policies, reviewing and discussing finances, and maintaining the overall goals set through the school and parish. 

The St. Mary's School Board meets monthly, generally on the first Monday of each month. The meetings take place in the school library and are open to parents and other community members.
