Since its founding in 1906 by the Sisters of the Immaculate Heart of Mary, Immaculate Heart High School has endeavored to continue its commitment to providing an educational program which addresses the needs of young women as these have developed and changed, generation after generation.  The school achieves this as an academic institution which is Catholic, private and college preparatory.

Immaculate Heart defines its mission as two-fold:

First, to share in the teaching apostolate of the Catholic Church by creating a learning environment where students can mature in their faith as they reflect on their special role as members of the Christian community.  Basic to this faith is the belief that:

God is the source of all life; and the dignity of all persons comes from being created in God's image, by being redeemed by Jesus and by being the recipients of His promise of resurrection; and the Gospel calls all people to truth, justice, honesty, service and compassion.

Second, to develop a significant foundation for the ongoing acquisition of skills, knowledge and values which will enable students to function not only as intelligent, informed and contributing members of their society, but as young women whose self-esteem, spirituality and life of faith motivates them to realize their own unique potential and allows them to discern carefully and to choose wisely those values which contribute to their own and others' authentic well-being and happiness.

Immaculate Heart strives to fulfill its mission by its commitment to a Christian philosophy, its stated goals, its program of instruction carefully designed to meet the increasing needs of women in the contemporary world, its liturgies and days of recollection, its activities, its policies and programs, all of which exist to foster the spiritual, social, intellectual and aesthetic development of the student.  In addition, Immaculate Heart's mission and purpose is facilitated by a competent, caring and supportive faculty and staff who have unqualified respect for the uniqueness of the individual and the religious and ethnic diversity of their students.

While Immaculate Heart recognizes that parents are the primary educators of their children, it is the intention of the school to assist parents by helping their daughters to develop in such a way that they will become women of great heart and of right conscience; knowledgeable and reflective about the global community in which they live; creative as problem solvers; capable of building on their appreciation of and acquired skills in language, art and science; sensitive to the need to be carefully and prayerfully discerning among the value systems that confront them; aware that learning is a lifetime endeavor; and convinced that, ultimately, all must develop within themselves a capacity for integrity, wisdom, humor, joy, peace and love, so as to "make gentle the life of this world."
