Mamaroneck High School

Boston Post Road building (former Junior High School), built in 1926

Auditorium Annex, constructed in 2005

The present campus is located approximately half a mile southwest of Mamaroneck's Harbor Island Park and spans the distance between Boston Post Road (U.S. Route 1) and Palmer Avenue. It comprises two primary buildings, one facing the Boston Post Road, and the other facing Palmer Avenue, with a hallway called the "overpass" connecting them. The "Palmer" building was constructed in 1925 and renovated in 1956 and 1964. The "Post" building was built in 1926 as the district's junior high school (grades 7-9).[4] In 1968, Hommocks Middle School was built and the Post building was annexed by the high school. The Palmer basement had served as the high school's cafeteria, but after this annexation the school opted to use only the middle school's cafeteria, in the space over the Post auditorium that later housed the "Apple" program.

A wooden gazebo used to stand near the Palmer end of the footbridge; it was a gift from the class of 1987. It was designed by an architectural-drawing-student, Brian Blum, and built by volunteer members of that year's class with support from architectural-drawing teacher Nick Cucchiarella.

The high school is one of the few in the area that has an open campus. Students are not obligated to stay on campus during lunch time and free periods. This has given rise to some safety concerns by parents, but by and large the community is supportive of the policy. During lunch time, students frequent nearby delis including Walter's Hot Dog Stand, just down a hill on the Palmer side. The open campus policy has been threatened to be suspended several times, particularly in wake of a string of bomb threats and false fire alarms in the late 1990s, although the campus remained open. The open campus policy was suspended in 2008 due to another string of bomb threats, but was later restored. In 2019, the school began requiring students to display a student ID as they enter through one of the two main entrances.

Formerly being two separate, independent school buildings, MHS has a wealth of facilities, including three computer labs, two gymnasiums, a football field, a baseball field, two parking areas, a TV studio, a large auditorium and a smaller theater. It offers a variety of educational and extracurricular activities, including architectural and engineering drawing, golf, tennis and fencing. MHS also has extensive programs to support students with disabilities. In 2006, construction was completed on a new science wing and a complex housing a library, tiered classroom, administrative offices, and guidance office. The Post side of the overpass was rebuilt and the room which had previously served as the library became the current cafe. The 28,000 square-foot three-story addition cost $15.8 million to design and construct. It was designed by Brian Snyder, AIA, of The Geddis Partnership, Southport, CT.[4] Mamaroneck is also the first public school in New York State to have its own beehives, starting in 2018. Students care for the bees and harvest the honey.

The field used by the football, soccer, lacrosse, and field hockey teams for home games is Memorial Field, between the Post parking lot and the neighboring Town Center. In 2011, artificial turf was installed and the bleachers were replaced. In 2019, the turf was replaced and a stone walkway was built around the bleachers. Manchester Field, usually called the baseball field, is overlooked on three sides by the Palmer and Post buildings and the overpass. It is surrounded by a square track used by the track and field teams.

Mamaroneck High school is unranked in U.S. News & World Report List of Best High School of 2012. However, its score of 55.2 in terms of college readiness[5] places it with the same rating as a rank of #262. In the U.S. News & World Report List of Best High Schools in 2017, it is Ranked #242 in National High Schools.[6]

Students also have the option to submit an AP Studio Art portfolio in either Drawing and Painting, Photography, or Clay.[7] In 2010, 2.415 AP tests were taken per graduating senior, and this garnered a ranking of 452 on Newsweek's annual list of Americas Best High Schools.

In addition, the High School also offers a large number of dual-enrollment courses. These include Introduction to Sociology administered by Syracuse University, College Composition by Iona College, as well as Intermediate Spanish/French, Introduction Creative Writing, a three-year program in Original Science Research with SUNY Albany.[8]
