History The school opened in September 1959 after Newton High School in neighboring Newton, which had served Sparta students, could no longer take on Sparta's rapidly growing high school-aged population. The sending districts of Hopatcong and Byram Township combined with Sparta to form the initial student body. In its first year of operation, Sparta High enrolled over 400 students enrolled in just three grades, from the three communities that shared the school. In May 1964, Sparta graduated its first class—of 160 students—that had attended the school for all four years.Our History, Sparta High School. Accessed December 22, 2024. "Sparta High School opened its doors in September of 1959 with a student population of about 420 in three grades representing three towns. Those towns included not only Sparta, but Hopatcong and Byram as well. Eventually Ogdensburg would also send its students to Sparta."
Hopatcong High School opened for the 1969–70 school year, with students entering 12th grade being the only Hopatcong students remaining at Sparta High School. The loss of students being sent from Hopatcong to Sparta caused enrollment of tuition-paying students to decline to 379, a drop of almost half from the prior year."Expect Enrollment Up 7½% In Sussex County Schools", The News, August 18, 1969. Accessed November 5, 2025, via Newspapers.com. "The county will have a new high school in Hopatcong Borough. Hopatcong High School will probably figure 625 to 650 students, according to John Auwenda, the school principal. It will be a six-year school, 7 through 12.... Tuition enrollment in Sparta High School is down 45 per cent, of 379 total, due to the withdrawal of 9th, 10th and 11th grade students from Hopatcong Borough."
Students from Byram Township had attended Sparta High School until 1974, when Lenape Valley Regional High School was created.Gansberg, Martin. "Netcong Links Its Problems to I‐80", The New York Times, September 29, 1974. Accessed December 14, 2016. "And taxes have taken a big jump because of the need for joining with adjacent Stanhope in operating a regional high school, Lenape Valley, which opened last week.... The reason for the increase is because Netcong had to join with Stanhope, which is in Sussex County, to construct the regional high school."Staff.

"The impetus for the creation of Lenape Valley was provided by Sparta...Byram was sending students to Sparta, and it was told by Sparta that they had to leave...Sparta was growing and could no longer take Byram Township students."
During the 1970s, Sparta High School instituted split sessions to help alleviate problems brought on by increased enrollment. This was only a temporary fix, however, and the township later approved a referendum to build an annex onto the back of the school, more than doubling its area. The section added a new cafeteria, a library, and open classroom spaces.
In the early 1990s, the open spaces provided by the built-on annex were renovated and became closed classrooms. By this time, over one thousand students—all from Sparta—were enrolled in the school. Later in the 1990s, the high school was expanded yet again, adding a new science wing and a number of technological upgrades.
In September 2006, Sparta residents approved a referendum to perform major renovations on the school. The construction began in the spring of 2008 and was completed by the beginning of the 2010-2011 school year. This reconstruction was to alleviate the issue of overcrowding that the school faced. During the construction, many classrooms were displaced to a cluster of modular trailer rooms."Residents narrowly spring for overhaul to aging Sparta High School" , News 12 New Jersey, September 27, 2006.
