Mater Dei Academy is guided by its mission statement which embraces a Catholic identity that is Christ-centered.   The school is committed to the person and Gospel of Jesus Christ as the basis of our values and attitudes which are reflected in our culture, policies, and procedures.  We are committed to faith formation of our students and the continuation of faith formation for our faculty through our academic program of religious studies and various opportunities outside the classroom.

Students receive daily religious instruction, participate in weekly liturgy, and are involved in various service projects throughout the school year.

The faculty meets the diocesan requirements for academic and catechetical preparation to provide effective religious instruction for all students.  They regularly participate in retreats and in-services to further their faith formation.

Mater Dei Academy collaborates with five Catholic parishes in neighboring cities in Lake County to provide Catholic education.
