The Oyster Bay-East Norwich Central School District is comprised of a small educational community serving a diverse mix of students in three schools: Theodore Roosevelt Elementary School (Grades K-2), James H. Vernon School (Grades 3-6) and Oyster Bay High School (Grades 7&8, 9-12). The district's 13.1 square mile boundaries include the hamlets of Oyster Bay and East Norwich and the incorporated villages of Centre Island, Oyster Bay Cove, Cove Neck, and portions of Mill Neck, Muttontown, Laurel Hollow, and Upper Brookville.

Both Oyster Bay and East Norwich's schools have a long history. The Oyster Bay school system began with the support of James Townsend of Oyster Bay who was on the Board of Regents of Columbia University from 1784-1787. In April, 1802, he helped establish the Academy from which the public schools of Oyster Bay developed in 1865. The East Norwich school system had its official beginning at the annual meeting of elders on February 2, 1838. The Oyster Bay-East Norwich Central School District was created on July 1, 1960 by the action of the voters in the former Oyster Bay and East Norwich School Districts. This merger brought together two well-established school programs for the purpose of providing outstanding educational opportunities for the students of the area.
