School Notes

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 cooperation over self-interest, and we encourage all members of our community to explore their place in the larger world beyond our campus.

Founded in 1865, St. Mark's School educates young people for lives of leadership and service, challenging students to take charge of their education, inspiring their academic and spiritual curiosity, and kindling their passion for discovery.
We have crafted an intentionally small community with the specific goal of encouraging close relationships between faculty and students that gives our students courage to stretch, to dream big, and think beyond themselves.Innovation and tradition are part of our educational DNA.
The "school under one roof" design of our main building, an outstanding academic program that combines traditional classroom techniques with experiential learning, a culture that stresses social justice and global perspective, and an athletic program designed to challenge both college-bound athletes and those seeking fitness alone, all come together to create a robust environment unique to St. Mark`s. Graduates leave St. Mark`s ready to live lives of consequence in the 21st century.

When I attended, St. Mark's employed the best English teachers anywhere. We learned the art of writing. Ben Bradlee, who edited the Washington Post for decades, attended St. Mark's. All their lives, students remember the athletic program. When one attends school with someone, one remembers those classmates as long as one lives.

St. Mark's does many things well: The school fosters and encourages an environment where diversity is embraced, students have voice and recognition, and relationships are strong. The generally positive atmosphere represents the student body, which is full of many different types of people. The many opportunities to pursue academic interests both inside and outside the school makes SM a great prep school. Lastly, the athletic teams value perseverance and hard work over winning, and the coaches are very skilled.
