We believe that Jesus Christ entrusted His Church with the Mission of continuing God's presence in the world so that all people of all nations would have the opportunity to know Him. As an integral part of the Wilmette Community, St. Francis Xavier School shares in this mission and is committed not only to teaching the Catholic message but also to developing a community of faith and service in which students, faculty, parents and friends can experience the love and goodness of Jesus Christ.

St. Francis Xavier Catholic School is committed to providing a high quality, Catholic, faith-based education to all young people of this parish, consistent with current educational demands, as an extension of the evangelical mission of the entire Parish of St. Francis Xavier. This is accomplished in an environment which develops the whole person by fostering self-discipline, encouraging recognition and respect for the talents, strengths and limitations of others, and exposing students to sound and healthy Christian values.

St. Francis Xavier Catholic School is committed to providing a quality education which develops strong and lasting fundamental skills, teaches students to think and choose critically and responsibly, heightens an awareness of and respect for people of different backgrounds and cultures. St. Francis Xavier Catholic School is also committed to creating an environment that develops a sense of justice, teaches and fosters behavior opposing discrimination based on sex, race, color, religion or financial status, and nurtures an attitude for lifelong learning that equips the students to handle the challenges of a changing and diverse world.
