History and organization
The first Plainedge school was housed in a two-room, wood-frame schoolhouse that became known as the "Annex." It served the district until about 1952 when the John H. West elementary school was built. It was then updated and used as the school district's administration office.

On February 19, 1985, the Plainedge School Union's Board of Education was sued by Carl McCall for a refusal to promote her allegedly based on her gender.

The school district is composed of 3 elementary schools, John H. West elementary, Eastplain elementary and Charles E. Schwarting elementary. The middle school is Plainedge Middle School and the high school is Plainedge High School. Former schools include Robert E. Picken elementary, which was sold to the Town of Oyster Bay to serve as a smaller town hall for the southern part of the town; Northedge Elementary (then a kindergarten), which was knocked down to make room for the new middle school; Baldwin Drive Elementary and Southedge Junior High, which were demolished and the land sold for housing; and Sylvia Packard Middle School, which was closed after 40 years.

Since Plainedge is not an official town, its students come from parts of Massapequa, North Massapequa, Bethpage, Seaford and Farmingdale.

As a result of school closures caused by the COVID-19 pandemic, the district arranged a community effort to turn on stadium and porch lights between 8:20 and 8:40PM on May 1, 2020 to honor the graduating senior class.
