History The efforts to create a high school began after the district was notified by the Dover School District in 1957 that Randolph students would no longer be accepted at Dover High School for the 1960–61 school year. The partially completed school opened for grades 7–12 in September 1961 on a site and was constructed at a cost of cost of $1.75 million (equivalent to $ million in ) for students from Randolph and those from Jefferson Township, who attended as part of a sending/receiving relationship until the 1964–65 school year, when Jefferson Township High School opened."Randolph High School: Timeline", Daily Record, May 17, 2005.

The school was named by Redbook magazine in April 1992 as the best high school in the state, recognizing the school for its academic and extracurricular performance.van Tassel, Priscilla. "'Smiling School' Wins National Recognition", The New York Times, May 3, 1992. Accessed November 19, 2020. "Don't tell Ridgewood High School, Westfield High, Moorestown High or any of the other schools in New Jersey that are often touted as the best in the state, but Redbook magazine, in an article in last month's issue on the nation's public high schools, has proclaimed Randolph High School as New Jersey's finest. This 1,200-student high school in Morris County, known more for its performance on the athletic field than off, may not have the recognition factor of some other schools, but it has in fact been gathering laurels in academic subjects and extracurricular activities as well as sports for most of its 30 years. And that was what led Redbook's panel of judges to select the school from among the 25 that applied for the honor."
