CDU is authorized to award the Catechetical Diploma, a valuable teaching credential in the Church. CDU was the first Catechetical Institute in the United States to award the Catechetical Diploma and teach the Faith to adults using distance education exclusively.

Responding to the commission Christ gave to his followers to make disciples of all nations, each person is called to share the Gospel message of God’s love. Through systematic study of the profession of Faith, liturgy, Sacred Scripture, moral teachings, and spirituality, students achieve this ecclesiastical teaching certificate and equip themselves to teach the Faith with authority and confidence. Courses in the diploma program award undergraduate credit.
