History Starting in 1954 and continuing into the 1970s, students from Delran Township attended Riverside High School as part of sending/receiving relationships, along with those from Delanco Township.Wolk, Mike. "State Tells Delran to Cut $7.8 Million Cost of School", Courier-Post, October 14, 1972. Accessed April 28, 2021, via Newspapers.com. "Delran high school students are still being bused to Riverside High School as they have been since 1954. An agreement between the two towns allows Delran to continue busing its students to Riverside 'until the new high school opens as long as we're working on it.'"

To address overcrowding at Riverside High School, efforts to merge the three districts in Delanco, Delran and Riverside Townships into a combined regional K-12 system were rejected in a November 1971 referendum, with Delran Township voters in favor of the regionalization and the voters in the other two municipalities opposed.Andrews, Margot. "School Merger Vote Defeated in Burlco", Courier-Post, December 1, 1971. Accessed April 28, 2021, via Newspapers.com. "Voters in fast-growing Delran township indicated last night they would like to join with two neighboring towns in a regional school district. But their neighbors in more-settled Riverside and Delanco scotched the idea.... Delran undoubtedly will have to build a high school on its own, they said, and the other towns will have to build new elementary classrooms. Delanco and Delran High School pupils now attend the Riverside facility, which, according to Superintendent John Bodnarik, is overcrowded." The school, constructed at a cost of $6 million (equivalent to $ million in ), opened for the 1975–76 school year with 864 students in grades 9–12."Delran High to be dedicated Sunday", Courier-Post, November 12, 1975. Accessed April 28, 2021, via Newspapers.com. "The new $6 million Delran High School, which opened this fall, will be dedicated Sunday at 2 p.m.... The school, located on Hartford Road, is the township's first public high school. Previously, township teenagers attended Riverside High School."Curran, Karen. "High schools in Delran, Evesham ready to open", Courier-Post, August 21, 1975. Accessed March 13, 2022, via Newspapers.com. "New high schools will open in both Delran and Evesham this fall, but the concepts under which each school was built are vastly different. Delran, which had been sending high school students to Riverside, will open its own $6 million high school with 864 students in grades 9 through 12.... On the other hand, if it were entirely Delran's choice, assistant superintendent Anthony Casale thinks his district might have preferred to form a region with Riverside and Delanco. In 1971, the boards of education in the three towns approved and put to the voters a referendum for a regional school district. Delran passed the referendum, but the other two districts turned it down. Since Riverside High School, Delran's receiving district, was overcrowded, the only choice left was a new high school for Delran alone."

Expansions In 2008, a referendum was passed, which included $25.8 million in spending that included construction of a new science wing to the school as well as renovations to the existing building."Voters Approve $106 Million in School Construction", New Jersey School Boards Association, December 10, 2008.
