Cresskill High School

Cresskill High School is a four-year comprehensive public high school that serves students in ninth through twelfth grades from Cresskill in Bergen County, in the U.S. state of New Jersey, operating as the lone secondary school of the Cresskill Public Schools. The infrastructure is shared with Cresskill Middle School, which serves Cresskill students in sixth through eighth grade.

As of the 2024–25 school year, the school had an enrollment of 489 students and 49.5 classroom teachers (on an FTE basis), for a student–teacher ratio of 9.9:1. There were 18 students (3.7% of enrollment) eligible for free lunch and 4 (0.8% of students) eligible for reduced-cost lunch.

Cresskill's students in grades nine to twelve had attended Tenafly High School until October 1962, with the opening of the initial wing of Cresskill's high school, constructed at a cost of $2.8 million (equivalent to $29.8 million in 2025). Students already in the Tenafly district for grades 11 and 12 when the Cresskill school opened remained at Tenafly High School until graduation, which meant that the first Cresskill graduating class was the Class of 1965.

In September 2021, Hurricane Ida caused millions of dollars in damages to the school facility. Students were put into a local Catholic school St. Therese until repairs at the high school were completed months later.
