Pupils going on to high school in the early years attended Hempstead or Jamaica High Schools. Overcrowding of these schools in the 20’s saw Floral Park seek its own high school. In 1926, a Central High School District was formed and Sewanhaka High School opened its doors in 1930.

Sewanhaka became overcrowded and, although Floral Park – Bellerose residents wished to withdraw from the Central High School District, efforts to do so were voted down in 1954 by the rest of the component districts. The final effort was the construction of a junior-senior high school in each member district, and Floral Park Memorial opened its doors in 1957.
