History Through the 1957-58 school year, students from Mahwah joined those from Allendale, Saddle River and Upper Saddle River who attended Ramsey High School as part of sending/receiving relationships with the respective districts and the Ramsey Public School District. Allendale and Mahwah left the Ramsey district in September 1958 once Mahwah High School was opened. With construction delayed due to labor actions, Mahwah High School started the year with afternoon classes housed in space rented at Ramsey High School. Completed at a cost of $3.6 million (equivalent to $ million in ), the high school facility opened for students in February 1959. Allendale and Upper Saddle River switched to Northern Highlands Regional High School when it opened in 1965.
