Croton-Harmon High School

Croton-Harmon High School (CHHS) is a public high school located in Croton-on-Hudson, New York. It is administered by the Croton-Harmon Union Free School District, and serves 9th-12th grade students. As of the 2023-2024 school year, 508 students were enrolled, with a student-teacher ratio of 10.77.

Due to an increase in students since its original construction, the school was expanded in the 1950s with a gym, and again in 2005–2006 with eight new classrooms, an auxiliary gym, and a new library. Between 2006 and 2017, the library also included a space for students to use desktop computers. In 2017, the school received a grant for a Nureva Span system, which replaced the desktop computers in favor of a more collaborative learning support system.
