The story
The school was originally organized in 1970 as a rural segregation academy on a sea island near Charleston, South Carolina with the name Sea Island Academy. When the school first opened, classes were held in a local Episcopal church. In 1971 Sea Island Academy merged with Sea Island Baptist School, founded in 1966 by the First Baptist Church of John's Island.
The school was renamed Charleston Collegiate School in 2002, and presently occupies a 30-acre (120,000 m2) campus, built in 1972.
