The Academy assists the parents in bringing the young to maturity. Conscious of this responsibility and aware of the inseparability of the intellectual and moral life, Mater Dei sets rules of conduct becoming to Christians.

Discipline is based on the love of God, observance of the Ten Commandments, and a strong moral character. The positive attitudes of respect for authority, at home and at school, and responsibility for one's own actions are emphasized at Mater Dei.

Through a combination of firmness and compassion, not permissiveness, the Academy fosters the positive attitudes of respect, obedience and responsibility to duty.
