About Middlesex School
We want to educate our students’ hearts as well as their minds, and we want our graduates to do good in addition to doing well
Middlesex School is a coeducational, non-sectarian, independent secondary school located in Concord, Massachusetts. Founded in 1901, it offers a rigorous college-preparatory curriculum for grades 9 through 12, emphasizing intellectual inquiry, creativity, and community within a supportive residential setting.
Core Values
Teaching Philosophy
Our advising program ensures that each student is matched with a faculty member who knows and guides them in all aspects of school life. The Advising Program helps ensure that each student succeeds in the full sense of the word, helping students navigate all aspects of Middlesex life (and often beyond). Our students achieve writing excellence largely through our Sophomore Writing Workshop, a weekly seminar aimed at mastery of expository composition. Through weekly writing assignments, interactive plenary sessions, and one-on-one feedback, our students learn how to compose carefully constructed paragraphs that form the basis of eloquent, organized essays. All Middlesex students learn mindfulness exercises to train and stabilize their attention, as well as how to relate skillfully to emotions, feelings, and thoughts.

The school has appointed an Associate Director of Diversity, Equity, and Inclusion and maintains an International Student Association as an affinity group.
