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.
Founded in 1901, and located in one of this country's most historic towns, Concord, Massachusetts, Middlesex aspires to help its students "find their promise" through immersion in a rigorous academic program, inclusive extracurricular programs in arts and athletics, and a commitment to service. Middlesex students are exposed to a breadth and depth of opportunities typically found at only a much larger school.
Over 150 classes include five languages, a much emulated Writing Program, and over 50 advanced and AP sections that wil stretch students intellectually as they pursue academic passions.
At Middlesex, everyone engages in cocurricular life, participating in a thriving arts program (including a third of the school performing via vocal, instrumental or dramatic groups) that ofters opportunities for the beginner to high-end artist; similarly, each student participates in athletics, and we have a home for both the elite athlete and those new to team sports.
All of this work takes place in a community strengthened by our shared commitment to five core values: honesty, respect, kindness, gratitude, and courage.
