The Mount Sinai School District is a United States educational division of the Mount Sinai, New York community in the Town of Brookhaven on the north shore of Long Island. Established in 1870, the district oversees three schools that serve approximately 2,200 students located in a six square mile area. The Board of Education for the district consists of seven members, including a president and a vice-president. The 2020-2021 budget was about $61,000,000. The location of the original school building is unknown; however, tradition places it on North Country Road east of Mt Sinai Coram Road. The second one-room school was built in 1870 on a half acre of land on the southeast corner of North Country and Mt Sinai Coram Road and in 1908 a second classroom was added. This building served the community until 1960. At that time the community decided to send their children to be educated in Port Jefferson School District. In 1960, the school was moved and a firehouse was built on the original property. Schools Mount Sinai Elementary School Opened in 1966, serving grades kindergarten through 4th grade.
