Campus
Abby Kelley Foster started with Grades K-5 in a factory building. The middle and high school programs came later and are located in adjacent buildings. There are 3 buildings in this campus. The Elementary, Middle and High School buildings. They are located next to Kendrick Field which provided them with a great place to have field days, but in the year 2009 they transformed the old building next to it into a new playground and 2 athletic fields. They also made a high school. They made another old building into a full court gym for the Elementary and Middle Schools in 2008.

Adjacent to the Auditorium and Gym is a warehouse that the school uses for various storage and projects, such as the school play.. More classrooms were built in the High school due to overcrowding during the 2016-2017 school year. They are now opened for the 2017-2018 school year.
