Catholic University School is a private, Catholic school for boys from 3 years to 18 years, and for girls for pre-school.

Under the Trusteeship of the Marist Fathers, CUS is located in the heart of Dublin, on Lower Leeson Street

The Marist Order was founded in 1836 and almost immediately the Marists set up schools which emphasised excellence in learning and provided a context which would develop a pupil's sense of values in accordance with the Gospel. We believe passionately in the value of the education that we provide to the pupils who attend Catholic University School.

The best way to learn is through experience and we believe that CUS offers an experience of a Christian community that will help each pupil that comes to it to become the person that God intended him to be. We believe in providing a balance in pupil's lives by offering opportunities to develop rounded personalities and a sense of responsibility in their personal lives. We do this because we believe in educating the whole person - their minds and bodies but above all their hearts and spirits.
