What is your affiliation with Columbia University?

Columbia Grammar School was founded in 1764, just ten years after the founding of King’s College, which later became Columbia College, now part of Columbia University. Originally established as a boys’ preparatory school for Kings College, Columbia Grammar School functioned for 100 years under the direct auspices of the college. In 1864, the trustees of Columbia College terminated their relationship with Columbia Grammar School, and the School became a proprietary institution, achieving its non-profit status in 1941.

In 1956, we welcomed more students into our community when we merged with the neighboring Leonard School for Girls and became a co-educational institution. Leonard’s interconnected brownstones on West 94th Street are home today to our prek through second grade students.

In 1969, the School’s name was officially changed to Columbia Grammar & Preparatory School. Shortly thereafter, we began a tremendous physical expansion project, which today is now the largest campus in Manhattan, educating nearly 1,300 students from PreK to Grade 12.

In 2014, we proudly celebrated our 250th anniversary as one of the oldest independent schools in the United States. In 2017, Dr. William M. Donohue was appointed as only the 14th Head of School in the School’s history.
