Rainwood Memorial Elementary School is a school owned by the Rainwood family, which was opened after the Rainwood Day Camp & Learning Center was shut down. Approximately six months prior to December 2011, a student mysteriously vanished from the school, causing it to lose tuition money when parents opted to stop sending their children. However, the school did not close due to the dining hall being rented by an outside party. The Order has seemingly used the school as a meeting place and may have been responsible for renting out the building. The Slender Man has also made at least one appearance within the school.
The building remained in use until late 2012, at which point it was closed and those working at the school, such as Matt Sharky, were left unemployed. When Chris, Alex, and Daniel Shipman visited the school in January 2013, they found that the building had been completely shut down.
