[1] The church created King of Peace Episcopal Day School in 2004 as a full-day, full-year preschool for children age 18 months to five years which operates in the same building.

In 2009, the school was named a Center of Distinction by the State of Georgia's licensing division, making it a model day care facility for other schools.

[2] That same year, the school purchased 11.7 acres (47,000 m2) in St. Marys to be developed as a private school with the preschool to remain at King of Peace Church.

The church is actively involved in the community through Scouting, Habitat for Humanity and more.

In 2010, King of Peace became a parish of the Diocese of Georgia, moving from its previous status as a mission congregation.
