Middlesex School

Middlesex School is a coeducational, non-sectarian, day and boarding independent secondary school for grades 9-12 located in Concord, Massachusetts. It was founded as an all-boys school in 1901 by a Roxbury Latin School alumnus, Frederick Winsor, who headed the school until 1937. Middlesex began admitting girls in 1974. The school is a member of the prestigious Independent School League and is one of five schools collectively known as St. Grottlesex. 
The school was named for the county Middlesex in which it stands. The campus was designed by the Olmsted Brothers architectural firm, and the firm Peabody and Stearns designed most of the main buildings. A recent addition is the Clay Centennial Center, completed in 2003, which hosts science and math classes as well as an observatory with an 18-inch research grade telescope.
The school is 70% boarding students and 30% day students. In 2019-20, boarding students came from 24 states and 20 countries. Middlesex School is highly selective, accepting only 14% of students who applied to enter in 2022-23. 
Campus and facilities.
The Middlesex School campus is located in Concord, Massachusetts, about 20 miles outside of Boston. Most of the campus buildings are located around The Circle, a grassy field at the center of the school. There are four dorms for boys (Clay, Landry, Robert Winsor, and Atkins) and five dorms for girls (Bryant-Payne, Higginson, Hallowell, LeBaron Briggs, and Kravis). There are three academic buildings: the Clay Centennial Center, constructed in 2003, Eliot Hall, which also houses several administrative offices, and the Rachel Carson Music and Campus Center, which houses the music, drama, and Spanish classes. In January 2019, the School opened the new Bass Arts Pavilon, a complex that contains two theaters, a gallery, and enhanced studio space for visual arts. The Warburg Library, besides housing Middlesex's collection of books and magazines, also contains classrooms and the Middlesex Archives. The dining hall is located in Ware Hall, as well as more administrative offices and the student center. Many members of the faculty live on campus, either in dorms or in several faculty houses.
At Middlesex, there are two turf fields for field hockey and lacrosse, five grass fields (for soccer, lacrosse, and football), a wrestling room, a dance studio, a baseball diamond, eight outdoor tennis courts, eight squash courts, two basketball courts, an ice rink, a boathouse and large pond (Bateman's Pond) for crew, and a fitness center (the James Oates '65 Center).

Community service.
Middlesex offers several community service programs. Students may help clean up a soup kitchen at Open Table (weekly), serve food and clean at a food pantry at Cor Unum (on long weekends), talk to people at a home for the elderly at Walden House (weekly), visit the elderly at Sunday Visits (special schedule), and help small children learn to skate at Gazebo (special schedule). Every fall, all students participate in a Community Service Day instead of going to classes. Several student Community Service Officers, all seniors, help manage the program.
Juniors may participate in the Youth in Philanthropy Program, which focuses on teaching students the techniques behind philanthropy and provides $10,000 for the students to distribute to worthy causes annually.
Every summer, the school sponsors a community service trip to the Linawo Children's Home in South Africa, where students tour the surrounding area, learn about South African culture and history, and assist in the operation of the shelter.
Chapel program.
The Middlesex community (the entire student body and faculty and staff) meets weekly in the school chapel for a speech given by a senior on the topic of the senior's choosing. Most speeches are given by one senior, though 'dual chapels' (chapel speeches given by two seniors) are permitted. Spots in the chapel program are allocated in the beginning of the school year.
Throughout the year, there are also several class chapels (gatherings involving one grade) and a few evening chapels, which are given by faculty members and outside speakers.
