History In the face of "badly overcrowded conditions" at Franklin High School, which served students from all four constituent municipalities, voters approved by a 4-1 margin a referendum in November 1972 for the creation of Wallkill Valley Regional High School."Voters in Sussex Approve 2 of 3 School Referendums", Paterson Evening News, November 29, 1972. Accessed November 18, 2021, via Newspapers.com. "The final tally was 1138 to 282 in approving the creation of a new regional high school district for grades 9 through 12 for students in Franklin, Hamburg, Hardyston and Ogdensburg.... By that vote, the four districts have paved the way for the formation of a regional board of education and granted authorization for a current expense budget of $30,000 for the regional board. High school youngsters from all four municipalities plus Vernon, are now attending Franklin High School under badly overcrowded conditions."

In December 1974, voters in the four constituent municipalities voted against a referendum that would have spent $10 million (equivalent to $ million in ) on the construction of a new building, as well as other questions that covered additions for a planetarium and a swimming pool."Voters Yell 'No' To HS in Sussex", Paterson Evening News, December 4, 1974.

"Voters In the four towns which comprise the Wallkill Valley Regional High School District left no room for doubt as to their general feeling about the construction of a $10 million high school, when they voted Tuesday almost 3 to 1 against the building referendum. The total vote from the four participating districts of Hardyston, Hamburg, Ogdensburg and Franklin was 1,527 no and only 631 yes. Included in that overwhelmingly negative vote was the defeat of two additional questions on the ballot: a $450,000 swimming pool and a $191,000 planetarium."

The district sought bids in 1979 for a building costing $8.3 million (equivalent to $ million in ), using funds from a referendum approved the previous year."Wallkill Valley to open bids for regional school", Paterson Evening News, July 24, 1979.
