From the SCHSL constitution
LEAGUE MEMBERSHIP - A non-public high school may become a member of the League if such
school is accredited by the Southern Association of Secondary Schools and Colleges and the principal
of the school agrees to conform to all rules and regulations of the League.
Before being considered as a member of the League, the non-public school must clearly define its
attendance area as one of the following: (1) the attendance area of the public school in whose
attendance area the school is located, (2) the school district in which the school is located, and (3) the
county in which the school is located.
