S.C. Code § 59-5-10
The State Board of Education shall be composed of one member from each judicial circuit. The members shall serve terms of four years and until their successors are elected and qualify, except of those first elected, the members from the fifth, tenth and fourteenth circuits shall serve terms of one year; the members from the first, sixth, eighth and twelfth circuits shall serve terms of two years and the members from the fourth, seventh, ninth and eleventh circuits shall serve terms of three years. The terms of all members shall commence on January first following their election.
The legislative delegations representing the counties of each judicial circuit shall meet upon written call of a majority of the members of the delegations of each judicial circuit at a time and place to be designated in such call for the purpose of electing a member of the Board to represent such circuit. A majority present, either in person or by written proxy, of the members of the county legislative delegations from a given circuit shall constitute a quorum for the purpose of electing a member, but no person shall be declared elected who shall fail to receive a majority vote of all the members of the county legislative delegations from the circuit. The joint county legislative delegations of each circuit shall be organized by the election of a chairman and a secretary and such joint legislative delegations shall, subject to the provisions herein, adopt such rules as they deem proper to govern the election. Any absentee may vote by written proxy. When the election is completed, the chairman and secretary of the joint county legislative delegations of each circuit shall immediately transmit the name of the person elected to the Secretary of State who shall forthwith issue to such person, after he has taken the usual oath of office, a certificate of election as a member of the State Board of Education. The Governor shall thereupon issue a commission to such person and pending such issuance the certificate of election shall be a sufficient warrant to such person to perform all of the duties and functions of his office.
Any vacancy shall be filled in the same manner as the original appointment for the unexpired portion of the term.
Representation of a given judicial circuit on the State Board of Education shall be rotated among the counties of the circuit, except by unanimous consent of all members of the county legislative delegations from the circuit. No member shall succeed himself in office except by unanimous consent of the members of the county legislative delegations from the circuit. Members of the legislative delegation of any county entitled to a member of the Board shall nominate persons for the office, one of whom shall be elected to the Board.
The Board shall select its chairman and other officers to serve for such terms as the Board may designate. Provided, the Superintendent of Education shall serve as secretary and administrative officer to the Board. The Board shall adopt its own rules and procedures. The chairman and other officers shall have such powers and duties as may be determined by the Board not inconsistent with the law.
At the initial meeting of the legislative delegations representing the counties of each circuit, it shall be determined by lot the sequence in which each county shall be entitled to nominate persons for the office.
