School History
Overview
St. Mark's School educates young people for lives of leadership and service.
Founded in 1865 as an intentionally small residential community, the School challenges its students to develop their particular analytic and creative capabilities by both inspiring their academic and spiritual curiosity and kindling their passion for discovery.
We value collaboration over self-interest, and we encourage all members of our community to explore their place in the larger world beyond our campus.
Deerfield Academy is an independent secondary school committed to high standards of scholarship, citizenship, and personal responsibility.
Through a rigorous liberal arts curriculum, extensive cocurricular program, and supportive residential environment, Deerfield encourages each student to develop an inquisitive and creative mind, sound body, and strong moral character.
Set in a historic village bounded by river, hills, and farms, Deerfield inspires reflection, study and play, abiding friendships, and a defining school spirit.
A vibrant, ethical community that embraces diversity, the Academy prepares students for leadership in a rapidly changing world that requires global understanding, environmental stewardship, and dedication to service.
