History
The West Windsor-Plainsboro Regional School District was the result of the 1969 merger of two separate, neighboring school districts - the Plainsboro School District and the West Windsor School District - as the population of both municipalities was starting to grow rapidly. The districts merged so that they could accommodate the increasing number of students newly enrolling. Dutch Neck and Wicoff elementary schools were constructed well before the establishment of the regional district.
Constructed at a cost of $8 million (equivalent to $58 million in 2025) and designed to ultimately accommodate an enrollment of 1,300 students in grades 7-12, West Windsor-Plainsboro High School (since renamed as West Windsor-Plainsboro High School South) opened in 1973 for grades 7-10, with students in grades 11 and 12 completing their education at Princeton High School.
