School Board


The St. Josaphat School Board provides consultation and advice to the leadership of St. Josaphat School. The school board’s role is to support the mission of the school, assist the administration with projects and programs as requested, evaluate and review policies, promote and facilitate communication among parents and the administration, and receive and evaluate feedback from various sources.


In addition to the standing members (the pastor and the principal), as well as the appointed members (the assistant principal and a PTO representative), the School Board consists of twelve elected members who are either parishioners of St. Josaphat Parish and/or parents/guardians of children at St. Josaphat School.  Elections for new members, as well as officers, are held annually in May.
