The Greenwich Board of Education offers four magnet elementary schools and one magnet middle school that accept students through an application process. The magnet school program is designed to serve three purposes:
- To advance and enhance student achievement by providing parents and students with educational options. Each magnet school offers a range of distinct education programs. Some emphasize particular academic subjects, while others use specific instructional approaches. Parents are encouraged to apply to those schools that they believe best meet the needs and interests of their children.
- To support the racial, ethnic, and economic diversity of all of the district's schools while complying to racial balance requirements established by the Connecticut legislature and the State Board of Education; and,
- To optimize the use of school facilities by balancing the distribution of students among elementary schools.
