Delbarton School, an independent, Roman Catholic learning community conducted by the Benedictine monks of St. Mary's Abbey with their lay colleagues, welcomes young men in grades 7-12 from diverse backgrounds, and challenges them to pursue excellence, to develop leadership, and to build character by educating the whole person: mind, body, and spirit.
Our programs in the arts, activities, athletics and ministry aim to deepen student involvement in the life of the school beyond the classroom.
Delbarton seeks to enroll boys of good character who have demonstrated scholastic achievement and capacity for further growth.
In turn, the faculty strives to support each boy's efforts toward intellectual development and to reinforce his commitment to help build a community of accountable persons.
The faculty encourages each boy to become an independent seeker of information, not a passive recipient.
Each boy must assume responsibility for gaining both knowledge and judgment.
