History
Prior to the construction of the high school, students from Hillsborough Township attended Somerville High School for grades 9-12 as part of a sending/receiving relationship. The Somerville Public Schools had notified the district in the early 1960s that Hillsborough students could not be accommodated in Somerville after 1968. The Hillsborough district attempted unsuccessfully to seek partners for a regional district and had voters reject by a nearly 3-1 margin a 1964 referendum that would have allocated $2.9 million for a high school. By 1966, Hillsborough was paying tuition for nearly 500 students to attend school in Somerville for grades 9-12, with that number expected to grow to exceed 900 by 1968.
Constructed at a cost of $3.5 million (equivalent to $30.7 million in 2025), the not-yet-fully-completed school opened in September 1969 with 730 students in grades 9 and 10, with those in grades 11 and 12 completing their high school education in Somerville.

The Student Diversity Initiative
The Student Diversity Initiative is a student-run group that strives to promote unbiased, authentic discussion, thorough education, and widespread awareness of diversity issues to make systemic changes in schools and communities. The ultimate goal is to cultivate community conversations at every level to shift perspectives and to challenge prejudice within NJ. In 2020, the Student Diversity Initiative hosted a National Day of Racial Healing, and a Christmas Donations to Children in Need. In 2021, they hosted The Black Experience in America: A Closer Look - a panel in honor of Black History Month, spoke at Kean University to numerous NJ school districts, and hosted conversations with teachers, businesses, schools, and administrators to help evolve the current curriculum.
