History Ridgewood High School was created in 1892, with the creation of a formal ninth grade class and a sophomore class was added the following year. A high school building was established in 1895, and the school received formal recognition from the state as an approved high school. The campus includes one central building, which, along with the original gym, was completed in 1919 at a total cost of $285,000 (equivalent to $ million in ). The building features brick walls, a slate roof and other stone features. The building was planned to be opened at an earlier date but it was postponed because of World War I. The building was designed by the architectural firm of Tracy and Swartwout, which also designed the Missouri State Capitol building. Students from Glen Rock had attended the high school for grades 10-12 from the time the borough was created. The Glen Rock district was informed in March 1952 by Ridgewood that its students could not be accommodated any longer in Ridgewood after the 1954-55 school year. Glen Rock High School opened in September 1956 with only tenth graders, as those in eleventh and twelfth grades completed their education through graduation at Ridgewood High School. The newest part of the school, the science wing, was completed in 2001 and contains 15 laboratory classrooms, three computer labs and a new industrial arts center. A new fitness center, gymnasium, and multipurpose room, the Campus Center, were also included in the renovation. Due to their proximity to the Ho-Ho-Kus Brook, the school's fields often flood during heavy rains and spring runoff.
