The district was established in March 1956, with the first school opening on September 1, 1958, at what is now West Morris Central. The district originally included Mount Olive Township, until that municipality voted to leave the regional system. Students from Mount Olive Township attended West Morris Central High School until 1972. West Morris Mount Olive High School, in Flanders, opened in 1972 and was operated by the regional district until the 1978-1979 school year, with the West Morris Mount Olive High School Class of 1978 being the last graduating class from this facility under the regional administration. The high school building and remaining faculty became part of the Mount Olive Township School District and is operated as Mount Olive High School. In June 2015, a feasibility study requested by Chester Borough, Chester Township, Mendham Borough and Mendham Township was released that discussed potential restructuring of the West Morris Regional High School District, considering two different options. In one scenario, West Morris Mendham High School would be stripped away from the district to become a standalone regional high school for the Chesters and Mendhams. In the second scenario, the existing PreK-8 districts would be dissolved and combined with West Morris Mendham to create a consolidated PreK-12 district. In either scenario, Washington Township would take over West Morris Central High School and become its own PreK-12 district. Significant tax savings would have been achieved for the Chesters and Mendhams under both scenarios, with equivalent tax increases for Washington Township.
