St. Peter's Episcopal School is accredited with the Southern Association of Independent Schools. The school adopted a "Go Healthy, Go Green" commitment that encompassed the entire school focusing on making sustainable changes to not only the campus but to the diet of the students that attended the school.

As part of its plan, St. Peter's partnered with Greenlife Grocery that provides a daily meal with food that uses organic and local food products. The school also provides monthly recipes and educational information for both parents and students in monthly take home menus and shares "Food for Thought" tips on health, wellness, and sustainability that are featured in the school e-newsletter. St. Peter's adopted community partners in order to complete this initiative that included local insurance companies, garden grants given by the local health department, and local farms. These efforts resulted in the students, parents and faculty incorporating healthier foods and exercise into their daily lifestyle.
