The first Bronxville Public School opened in 1870 in a one story frame building at about 80 Ponfield Rd., later the location of Woolworths and, since 1994, Value Drugs. The first principal and teacher was Grace Sandford (aka Mrs. Jared Sanford), who served for23 years. In 1908 the original frame building was replaced by a 10 room masonry structure, built at the same location, for $22,000 (USD), half of which was contributed by Mr. and Mrs. Fred R. Chambers of Bronxville. The building served as a school until 1924, and was known as the 'yellow brick' school. Total enrollment at the school in 1908 was 150 students. A "High School Department" was added in 1911, with the hiring of a single faculty member to teach high school subjects. In 1921, the Bronxville School added an eleventh grade to what had previously been called a 'junior high school', with a twelfth grade added a year later. Prior to that, students were sent to Mount Vernon, Yonkers or New Rochelle high schools, or to private schools, to complete their secondary education. Attendance at the Bronxville school had increased from 373 in 1920 to 443 in 1921. The present campus buildings were first erected in 1925 as separate elementary school and high school buildings. The two buildings were joined together in 1930 with the erection of a central portion, including a library and assembly hall. Attendance climbed as 41 students graduated from the High School in 1931, 69 in 1933, and 108 in 1937. In 1961 the campus was expanded with eleven new classrooms, a gymnasium and a cafeteria, as well as a complete renovation of the auditorium. Total attendance for the 1961 school year was 1,250, including 360 in the junior high and 290 in the senior high. Enrollment reached 1,490 students in 1974.. In 1934, Bronxville became one of the first public high schools in Westchester County to provide a continuous French language education for grades 7-12. It was added to the curriculum to promote the reading of the language and to allow students to feel achievement as they make progress in French. The teaching of advanced life sciences was added to the Bronxville School curriculum in hopes to teach students from kindergarten to high school how to think, ask questions, collect data, and come to conclusions. Students begin with basic concepts in elementary school, where they make observations. and in 2017 it had about 1,670 students. Roy Montesano, previously of the
Hastings-on-Hudson school district, became the superintendent in 2017, and was replaced by Dr. Rachel Kelly after Montesano's retirement in January 2023. In the early 2000s, there was substantial construction and renovation which, at one point, generated some letters of protest from students. ==The community of Bronxville==
