The Allen-Stevenson School is a private boys' school for kindergarten through eighth grade located on the Upper East Side of Manhattan, New York City, United States. It opened in 1883 and has been as its present location since 1924. The school has two divisions: Lower Division (K–4) and Upper Division (5–8) with a student body of approximately 389 pupils."The Allen-Stevenson School," US News, 2025. The head of school is Duncan Lyon, the fifth head to be appointed since the school's founding.

History The Allen School was founded in 1883 by Francis Bellows Allen at a home on Fifth Avenue and 57th Street. Its first class enrolled only three boys. In 1885, the school moved to rented rooms at Madison Avenue and 44th Street with an enrollment of twenty boys. In 1904, Mr. Allen met Robert Alston Stevenson, a tutor, who by chance had taken a room at 509 Fifth Avenue, where the school was then located. In 1904, Mr. Allen and Mr. Stevenson joined forces and then moved to 50 East 57th Street with 100 students. By 1918, enrollment exceeded 200. The school published its first newspaper, The Spotlight, and introduced an exercise program and team sports.

In 1924, the school purchased two brownstones for a new schoolhouse and moved to its present location on the Upper East Side. In 1939, Mr. Allen retired at the age of 80, after 56 years of service. In 1947, Mr. Stevenson retired after 43 years of service. His son, Robert "Huck" Alston Stevenson Jr., who had taught at the school, succeeded him as headmaster.

In 1950, Joseph C. Rennard became headmaster of Allen-Stevenson and served for nine years. The school introduced team sports at Randall's Island and required boys to wear navy blue blazers and gray flannel pants. In 1959, Henry Dyer Tiffany Jr. became headmaster until 1974. Under his leadership, a modern science lab and a paneled library, a gift from the Bell family, were added.

Allen-Stevenson's school song was composed by Rolande Maxwell Young in 1968, the year she joined the A-S faculty as a lower-school music teacher.Noble, Clifton Jr. "Remembering Rolande and Robelyn Schrade," The Republican, February 2, 2015.

In 1974, Desmond Cole (previously the head of United Nations International School) became headmaster and served in that capacity for sixteen years."Desmond Cole: Obituary." The New York Times, January 13, 2008. During his tenure, he created the Middle School division.

In 1983, the Allen-Stevenson School celebrated its first 100 years and published The Allen-Stevenson Centennial Album. Around that time, an East 77th Street addition, designed by Allen-Stevenson parent Alfredo De Vido, was built onto the school.

In 1990, the board of trustees appointed David Trower as Allen-Stevenson's seventh headmaster. In 2001, the school launched its first website to improve communication about the school.

In 2007, a total renovation-expansion of the school interior was completed, which preserved the school's Classical Revival brick and Victorian brownstone facades according to New York Landmarks Preservation Commission guidelines for the Upper East Side Historic District.

In 2008, the school completed a year-long celebration of its 125th anniversary. The board of trustees approved "Allen-Stevenson and Its Community", a policy statement about inclusion and community life.

In 2009, Allen-Stevenson was twice recognized for its work on energy and the environment, first with an Energy Star rating by the U.S. Department of Energy, and then by the U.S. Green Building Council (USGBC) for LEED Gold Certification for Existing Buildings (EB). This made Allen-Stevenson the very first elementary school in the United States to achieve LEED-EB Gold status.Stein, Harris, and William Jose Higgins. "The Allen-Stevenson School is the First Elementary School in the U.S. to Receive LEED Gold Award for Existing Buildings." Building Energy Performance Assessment News, January 2010.

In 2015, Allen-Stevenson filed an application to the New York City Board of Standards and Appeals to build two new buildings behind the facades of existing brownstones for expansion of classroom, arts and athletics space, and cap them with an 18-foot rooftop greenhouse.Chen, Jackson.

Admissions Allen-Stevenson has a highly selective admissions process. A financial-aid program ensures that the boys remain heterogeneous; as with many of its peer New York City schools. The school is private, functioning under a New York City non-profit statute, and is governed by a board of trustees and administered by a head of school.
