History Raritan High School was constructed at a cost of $1.5 million (equivalent to $ million in ) with an opening date of September 1962.

Accessed May 9, 2022, via Newspapers.com. "The first class to graduate from Raritan High School will be loyal to Raritan rather than Keyport where they have spent most of their high school time.

In May 2010, the Hazlet Township Board of Education embarked on a trial of "Going green to save green" by agreeing to enter into a power purchase agreement with a third-party vendor. Under this agreement, solar panels are to be erected on awnings over the student parking lot at Raritan High School and on the rooftop of Hazlet Middle School. The $7.5 million project will be funded by the vendor to cover the costs of construction and maintenance in their entirety and in return the Hazlet school district has contractually agreed to purchase the electricity at a below market cost. The district expects to save $1.7 million in energy costs over a 15-year period."Hazlet Township School District Goes Green to Save Green" . Accessed January 17, 2010.
