Stoneybrook Elementary School is a public elementary school in Stoneybrook, Connecticut.
It is not known which street it is on, but it is probably in the non-ritzy part of Stoneybrook because David Michael has to take a bus to school every morning when he moves into Watson's mansion in the ritzy area on McLelland Road. It is also not known whether there is a school uniform.
Most of the BSC charges attend the elementary school. It is in a neighborhood close to many of the BSC members because sometimes they take their charges to play on the playground. Kristy, Mary Anne, and Claudia also attended Stoneybrook Elementary as children.
