Columbia Grammar & Preparatory School

The school was originally called The Grammar School of King's College, after the original name of Columbia University. When the college changed its name during the American Revolution, so did the school, to Columbia Grammar School. The school dissolved its formal ties with Columbia in 1865. The word "preparatory" was added in 1969. The school has existed in several locations. In 1907, the school moved to its current location on 93rd Street, off Central Park West. Originally consisting of one building, it added five brownstones through its 1956 merger with the adjacent Leonard School for Girls. A building across the street was built in 1984, followed by two more in 1997 and 2001. An administration building was added to the school in 2009.

The oldest nonsectarian independent school in the city, it serves students from pre-kindergarten through the twelfth grade and offers a college preparatory curriculum. It was founded in 1764 by what is now Columbia University to teach future freshmen English, Greek, and Latin grammar. The school was originally called The Grammar School of King's College, after the original name of Columbia University. When the college changed its name during the American Revolution, so did the school, to Columbia Grammar School. The school dissolved its formal ties with Columbia in 1865. The word "preparatory" was added in 1969. The school has existed in several locations. In 1907, the school moved to its current location on 93rd Street, off Central Park West.

A building across the street was built in 1984, followed by two more in 1997 and 2001. An administration building was added to the school in 2009.

The school was founded in 1764 by the 10-year-old King's College as a preparatory school. It ran for 100 years under the direct auspices of the college. One of the most illustrious headmasters during that period was Charles Anthon, one of America's earliest and most distinguished classical scholars. During his tenure, the Grammar School provided over half the students to Columbia College's freshman class. In 1864, when Anthon retired as headmaster, the trustees of Columbia College ended their relationship with the Grammar School and the school became a proprietary institution. It would gain nonprofit status in 1941. In 1937, the Leonard School for Girls was founded, using several interconnected brownstones on West 94th Street (now part of the lower school). The school joined with the Grammar School in 1956 to become a coed institution. Richard J. Soghoian, who became the school's 13th headmaster in 1981, guided the physical expansion of the school from its 1906 home at 5 West 93rd Street to the present complex, which totals 215000 sqft with 14 buildings between 92nd and 94th streets. Soghoian retired in 2017. In 2017, William Donohue was headmaster, Sarah McLean was the Grammar School director (a predecessor, Stanley Seidman, retired in 2010), Paul Baly was the Middle School director, and Joanie Dean was the Prep School director. In 2024, William N. Moseley joined as the 15th Head of School. Abigail Rojas was the Grammar School director, Michelle Schackman was named Middle School director, and Dr. Scott Wilson was the Prep School director. In 2026, Rey Fernández was named as the 16th Head of School, moving from his previous title as Assistant Head of School. Abigail Rojas was the Grammar School director, Michelle Schackman was the Middle School director, and Dr. Scott Wilson was the Prep School Director

• Illustration — 5 West 93rd Street • Illustration — 94th Street Brownstones In 1984, the school built a new Preparatory School at 4 West 93rd, containing a full-sized gymnasium, three science labs, state-of-the art computer lab, library, three music studios, and nine classrooms. Columbia Grammar & Preparatory School greatly expanded its physical plant after 1985. Three new buildings and a fully renovated brownstone have, together with the existing buildings, added academic facilities as well as two new theaters, several computer labs, a variety of art studios and space for a growing music program. The Grammar School is located in a series of five interconnecting brownstones on 94th Street just off Central Park, and the 1905 Columbia Grammar School building at 5 West 93rd Street. In addition to classrooms, these house two libraries, two art studios, a gymnasium, swimming pool, two music studios, a science lab, a computer lab, and the Grammar School cafeteria. In 1996, 36 West 93rd Street was completed, adding 42500 sqft of space to the physical plant. This building, which goes through from 93rd to 92nd Street, has two computer labs, five art studios, library, science labs, and classrooms for grades 5 and 6, a fully equipped theater, and a large cafeteria. In September 2001, the school added five classrooms, another full-sized gym, a state-of-the-art theater, and three floors of classrooms and science labs. Since then, many brownstones have been added, one entirely for offices, and one building dedicated to the arts. A walkway has been built behind the multiple brownstones to make them easier to navigate. In 2009, CGPS purchased several new brownstones, one entirely for the kindergarten, another for a science building, and one for administrative offices. The Prep School also added a new level to its library. The new CGPS Middle School opened its doors to students in grades 5, 6 and 7 on Thursday, September 8, 2016. Two floors were added to the existing 36 West 93rd Street building to create a 6th and 7th floor solely for these grades, while the remainder of the building has been renovated. The ground floor now features an expansive yoga and dance studio; the existing Prep School cafeteria has been renovated and a second floor cafeteria was added specifically for Middle School students. New art studios as well as a new library, three science labs, a rooftop play yard and twelve classrooms have been added to the building. The HVAC system has been updated and the building is fully handicap-accessible.
