The South Carolina Association of Christian Schools began in 1967 and is an organization of 80 member schools with a combined enrollment of nearly 11,000. Although most of the schools are church sponsored, SCACS is not an organization of churches. It is an association of schools. A diversity of schools make up our membership and are sponsored by Independent Baptist, Southern Baptist, Southern Methodist, Free Will Baptist, Bible Baptist, Presbyterian Church of America, Wesleyan, Bible Church, and others.

A few of the schools are sponsored by independent religious, educational organizations.
