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.

CHHS is noted for student achievement, testing scores, its science research, world language, and performing arts programs, university in the High School and Advanced Placement courses, and graduation and college attendance rates. The school is consistently ranked within the top 150 high schools in the United States.
