John Jay was built in 1968 and opened in September 1969 to accommodate the growth of the Wappingers School District. Prior to its construction, Roy C. Ketcham High School was the district's only high school, away in Wappingers Falls. The 1973 graduating class was the first class to have completed four full years at John Jay HS. John Jay's principal is David Kedzielawa.
In 2002, a new biology and chemistry wing was opened for these laboratory courses. In 2009, a new math wing opened on the first floor. The school was geographically surrounded by IBM Microelectronics before its closure, while today the former campuses house iPark and an Amazon distribution warehouse. The presence of IBM in the area helped to fund engineering programs at the school. John Jay offers many classes focused on engineering, with some classes utilizing college-level computer programs and mathematics. Some of the classes are eligible for college credit through the Rochester Institute of Technology.
John Jay's percentage of students going on to two- and four-year colleges has been around 90 percent in recent years.
