With the original Freehold High School holding double sessions and rapid growth projected in the district, even with the new Southern Freehold Regional High School (to be renamed Howell High School) on the way, voters approved a referendum in December 1963 by a nearly 3-2 margin under which the district would spend $161,000 (equivalent to $ in) to acquire sites covering 43 acres in Marlboro and 65 acres in Manalapan that would be used for future high schools. Due to delays in opening Marlboro High School at the start of the 1968–69 school year, students assigned to the school attended split sessions in the afternoon at Freehold High School. Constructed at a cost of $3.4 million (equivalent to $ million in), the school opened in late October 1968. Marlboro High School served all students from Colts Neck Township until Colts Neck High School opened in 1998.

Students are encouraged to apply and practice the academic knowledge gained in the classroom through participation in various competitions sponsored by the Future Business Leaders of America and the Federal Reserve Bank.
