Battle Ground Academy was founded in 1889 by a group of Williamson County citizens as a day school, but became a boarding and day school in 1922 to accommodate the numerous out-of-town students who had been boarding in private homes. The conversion to a boarding school officially excluded female students, who had been attending BGA since 1890. Women were allowed to attend BGA again in 1979, several years after the boarding program ended.
The original brick building was located at the site of the Civil War Battle of Franklin, at the corner of Columbia Avenue and Cleburne Street.The building burned in 1902 and was rebuilt farther down Columbia. The school began relocating in 1996 with the construction of a new Upper School on Ernest Rice Lane, and in 2003 the Middle School moved to the same location. The Lower School is on Franklin Road.
