In 1904, Collinsville Academy was built. The school had two stories and six rooms, and could accommodate about 400 students. The school was rebuilt in 1941 with the intention being to help the citizens of Collinsville retain jobs during the Depression, according to the older citizens of the community. A 20-room school was built to replace it, and continues to be used as an elementary school. A high school and junior high were built in 1995.[5][6][7][8]
