After ending a long-standing sending relationship to Ridgewood High School in the mid-1970s, Ho-Ho-Kus students started attending Midland Park High School. The small size of the Midland Park school and the lack of electives led to efforts in the mid-1990s to find another high school to serve students from the borough. Since then, high school students from Ho-Ho-Kus have been attending Northern Highlands Regional High School. The send / receive agreement between Ho-Ho-Kus and Northern Highlands began in the 1990s. In 2016, the Ho-Ho-Kus and Northern Highlands districts reached an agreement to extend the send / receive agreement through 2026 under a fixed-price contract by which Ho-Ho-Kus would pay $3.6 million for the 2016–17 school year, escalating by 2% a year to $4.3 million in 2025–26, regardless of the number of students from the borough sent to the high school.
