building formerly occupied by the Hercules Munitions Company and located at the corner of West Clay Avenue and Locust Street. However, industrial arts and physical education classes continued to meet in the previous school building. During this time, students from the surrounding municipalities of Garwood, Kenilworth, and Springfield attended Roselle Park High School on a tuition basis. On April 30, 1931, the cornerstone was laid for a new building for the high school to be located on West Grant Avenue adjacent to the Robert Gordon School that was to be constructed at a cost of $350,000 (equivalent to $ million in ). This building remains in use as the Roselle Park Middle School. In January 1961, Roselle Park voters rejected a proposal for the construction of a new high school that would have cost $2.5 million to build (equivalent to $ million in ). The current high school building opened to students in September 1963. In 1993, a new wing was constructed, adding three additional classrooms.
