The district was established with the passage of a referendum in January 1957 by the five constituent municipalities of Egg Harbor City, Egg Harbor Township, Galloway Township, Hamilton Township and Mullica Township by a 5-1 margin that allocated $1.7 million (equivalent to $ million in ) for the construction of what would become Oakcrest High School. Egg Harbor Regional High School opened in September 1960, with 150 students from Hamilton Township shifted out of
Vineland High School. The school was renamed as Oakcrest High School for the start of the 1960-61 school year. The school name was chosen based on its site on the crest of a hill amid oak trees. Absegami High School was established at the start of the 1972–73 school year as a school-within-a-school inside Oakcrest High School. Absegami had its own independent identity and held classes in the afternoons, while Oakcrest met during morning sessions. By a three-vote margin, voters in the district approved a referendum by 1,152-1,149 to spend $11.89 million (equivalent to $ million in ) for the construction of Absegami's own building on a site in Galloway Township. Absegami High School opened independently in its own building in September 1982. The new
Cedar Creek High School was planned to alleviate overcrowding in the two existing schools and serve students from Egg Harbor City and Mullica Township. Construction began in Fall 2008 and opened to students in September 2010. In 2009–10, the district had 3,296 students, its peak enrollment. Enrollment decreased afterward due to a decline in casino jobs. Between 2009-2010 and 2014 its enrollment declined by almost 6%. The district had been classified by the
New Jersey Department of Education as being in
District Factor Group "CD", the sixth-highest of eight groupings. District Factor Groups organize districts statewide to allow comparison by common
socioeconomic characteristics of the local districts. From lowest socioeconomic status to highest, the categories are A, B, CD, DE, FG, GH, I and J. ==Awards and recognition==
