S.C. Code § 59-25-800
The county board may, in determining whether or not a discrimination exists, recommend that the State Board of Education require all teachers in the district to be examined and recertified under the procedure then in force for the certification of teachers as to their qualifications and may thereupon require the trustees of such district to classify such teachers in accordance with such recertification for the purpose of fixing their salaries, to the end that the salaries of such teachers shall be based upon the value of the services rendered, it being found as a fact that each grade of teachers' certificates now outstanding is held by teachers of greatly varying efficiency, abilities and accomplishments. Should no appeal be taken from a decision of the county board making such recommendation, the State Board of Education shall carry out such recommendation.
