History With baby boomers filling the school beyond capacity, the Ramsey Public School District informed its sending districts of Franklin Lakes and Wyckoff in 1954 that it would no longer accept students from those two communities at Ramsey High School beyond the 1956-57 school year.Staff. "Enrollments Tax Schools In Bergen; Auxiliary Rooms Are Being Converted for Classes and Construction Is Pushed", The New York Times, September 4, 1954. Accessed November 14, 2017. "Crowding is a critical problem in the high schools of the triangular area embracing Wyckoff, Franklin Lakes and Oakland. They have united in a plan for a regional high school. How soon this plant will be ready is problematical, but there is pressure in the fact that Wyckoff and Franklin Lakes students will not be accepted at Ramsey High School after the fall of 1956." Oakland, which sent its students to Pompton Lakes High School, joined the other two districts in pursuing a joint regional high school."Regional High At Polls Jan. 26", The Morning Call, January 14, 1954.

Wyckoff and Franklin Lakes now send pupils to Ramsey High school and Oakland sends to Pompton Lakes High School."

After Ramsey High School issued an ultimatum to their sending communities, the creation of a regional high school was approved in 1954 by Franklin Lakes, Oakland and Wyckoff (often called the FLOW district for the initial letters in the names of the three communities) by a margin of 1,060 to 51."Voters Okay Three-Town High School", Ridgewood Herald-News, January 28, 1954.

A steel strike, bad weather and other construction obstacles delayed the opening of the new school building, forcing Ramapo High School to start the 1956-57 school year with evening sessions held at Eastern Christian High School in North Haledon, with the school day running from 2:45 to 7:00 PM."Quick Change Turns Eastern Christian High School Into Ramapo Regional High", Paterson Evening News, September 11, 1956.

In 1999, the district allowed students from Franklin Lakes to choose which high school to attend, ending the policy under which students in the eastern half of Franklin Lakes were required to attend Ramapo High School while those in the borough's western half were assigned to Indian Hills High School. Oakland students were generally assigned to Indian Hills while Wyckoff residents could select which school to attend.Aberback, Brian. "Split's end turns out successful", The Record, June 29, 2003.

"Four years ago, the students in the classes of 2003 at Ramapo High in Franklin Lakes and Indian Hills High in neighboring Oakland were the first to enter the district after the school board abolished a controversial policy known as the 'Franklin Lakes split' The policy determined which of the two high schools students from Franklin Lakes could attend. It created a suburban soap opera in Northwest Bergen County, replete with feelings of bitterness and resentment and accusations of class elitism. Under the policy, students from the more affluent east side of well-to-do Franklin Lakes went to Ramapo. Students on the west side had to go to Indian Hills, regarded as a fine school but not quite the equal of Ramapo in some respects..... In 1999, after years of debate, the 27-year-old split was abolished, giving all students from Franklin Lakes a choice between the two schools."
