S.C. Code Ann. § 59-49-150

A student who is a legal resident of this State may attend the school without paying tuition, but may pay fees for maintenance and food services unless he meets the poverty requirements as defined in the will of John de la Howe and by current rules or regulations of the State Department of Education defining measures of poverty. Notwithstanding these provisions, all out-of-state and international exchange students admitted to the school shall pay tuition and fees for maintenance and food services as determined by the board.
