Mission
St. William of York Catholic School is a Christ-centered academic community instilling Catholic beliefs and Gospel values; nurturing students' gifts of faith and intellect by surrounding them with a family of faculty, staff, and volunteers whose vocation it is to serve.  

Philosophy
St. William of York, as a Catholic school in the Arlington Diocese, views education as involving the whole person in an environment of faith, hope and love which is centered on the values of the Gospels of Jesus Christ.  We recognize each student as unique in gifts, interests, and needs, as we strive to educate each child spiritually, morally, intellectually, socially, physically, and aesthetically.

St. William of York Catholic School is a community of learners, teachers, parents, staff and resource persons who strive to make Christian community not simply a concept to be taught but a reality to be lived and experienced daily.  We believe we are called to create an atmosphere where each child is encouraged to grow and develop to his / her greatest potential, empowered to go forth and meet the challenges and needs of an ever-changing world.
