We believe that all children, regardless of the economic, geographic, Religious and social circumstances into which they were born, are enhanced by engaging in educational experiences that challenge their abilities and cultivate habits of excellence. All students enrolled at Cardinal Shehan School are recognized for their talents, abilities and special gifts. The Cardinal Shehan School Community will maintain high expectations of excellence for all students in order to assist them in achieving their fullest academic and personal potential.

Cardinal Shehan School is staffed by professionally prepared and committed laymen and laywomen who work side-by-side with members of three religious communities: The Sisters of St. Francis of Philadelphia, the Oblate Sisters of Providence, and the School Sisters of Notre Dame. Together, these dedicated educators work with students who are interested in developing their minds, sharpening their talents, and experiencing the Lord Jesus in their daily lives.

The special mission of the school is to work intensively to develop peace. Teachers work with students to equip them with peacemaking skills, while parents are called upon to work with the school in bringing peace to their households and communities. "Cardinal Shehan School is creating a peaceful world, one student at a time."
