  • 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.

    To me what makes Middlesex such a special place is the strong sense of community. With a small student-to-faculty ratio, you get to work closely with each teacher and develop relationships that often extend beyond. . .

    The two primary aspects that I believe differentiate Middlesex (MX) from other independent schools are its class schedule and its student body composition. MX has a six day class schedule; every week, students have. . .

    Middlesex sets its self apart from other schools through its tight-knit community and its passionate, caring faculty members. The faculty members here are more than teachers or mentors; they are friends and family. They are. . .

    The first unique aspect of Middlesex that comes to mind is our plaque tradition. It is and always has been a graduation requirement to carve a plaque and every single one is hung up. . .

    An aspect of Middlesex that truly sets it apart from other boarding schools is the strong relationships formed between the students and the faculty. Middlesex, probably by design, has it so that an individual can. . .

School Notes

  • Middlesex School Mission and History
  • Frederick Winsor wanted the school he founded in 1901 to be distinct from the church-affiliated boarding schools of the time, and from its beginnings, Middlesex School has occupied a unique place in the independent school landscape. It is a non-sectarian School with a positive sense of tradition and mission. It is a school with small-school intimacy and big-school opportunity, a school that early on sought students from every part of the country through a National Scholarship Program. As it has grown, Middlesex has broadened its national and international reach while always benefiting from its local surroundings-the human and cultural capital of the Boston/Cambridge area. Middlesex School, both in the present and in the past, has preferred capacity in many areas to specialization in one. We believe a transparent and familiar community is an ethical community. We believe in our students. From the start, Winsor`s mission was to "find the promise that lies hidden" in every student, and that message of individuality, hope, and possibility guides us today. Our campus, designed by the Olmsted Brothers firm, remains centered on its iconic circle. We are fortunate to live in a beautiful setting that naturally brings our paths and our lives together. Radiating from a common sense of place and purpose, Middlesex continues to prepare its students for a changing world. We have evolved in many ways since our founding over a century ago. We have undergone renovation, conservation, expansion, and constant transition in person and place. Yet our buildings, our fields, our programs, and our ethos still cleave to a human scale fostering collegiality and contact. Despite the school`s continuous transformation, our mission, with our students at the center, remains the same.
