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 (K–3), Middle (4–7) and High School (8–12) 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 (including a parking lot) 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. Due to overcrowding, the school leased space at Temple Emanuel for grades 6-8 during the 2002–2003 school year. High school building
The school board decided to build a new high school. The building was bought from Norton Abrasives and was completely refurbished. During the construction of the school, students were temporarily put an old school building on Ararat Street. The building opened for the 2009–2010 school year and is still currently functional. The building was equipped with an auditorium, gymnasium (named James Walsh Gym after the head of the board of trustees), Cafeteria and Library. There was also the installation of a chemistry and biology lab plus a lecture hall. 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. Athletic facilities
During the building of the new high school in 2009, the school also turned an old storage building and an old playground into a new playground. The adjacent parking lots were also turned into one small athletic and one large mixed use field. The playground and both fields are covered in Astro-turf. There was also one building located next to the small field that was turned into a full court gym and is used by the Elementary and Middle School. Curriculum
