Chicksaw's public schools were previously operated by the Mobile County Public School System. One elementary school, Hamilton Elementary School, was within the Chickasaw city limits and serves Chickasaw residents. In addition two magnet high schools, Chickasaw School of Mathematics and Science and the Clark School of Mathematics, Science and Technology, were in the city. Residents zoned to Hamilton are also zoned to Chastang Middle School.
Several years prior to 2009 officials of Chickasaw, Satsuma, and Saraland contemplated forming the "Delta School District." Around 2009 Chickasaw officials considered starting a plan to secede from the Mobile County school system after Mobile County officials considered closing the Chickasaw magnets, which together have a combined total of 14% Chickasaw residents; the rest of the students came from other locations, including the unincorporated area of Grand Bay. Mobile County considered moving the magnets to Shaw High School in western Mobile.
The present site of Chickasaw was, in the early 20th century before the city now standing was incorporated, a company town, wholly owned by companies such as the Gulf Shipbuilding Corporation. It was the subject of a Supreme Court of the United States decision (Marsh v. Alabama, 326 U.S. 501 (1946)), which stated that despite being a privately owned town, because it functioned as a town open to the public, the right conferred by the First Amendment to the United States Constitution cannot be abridged.
