Mississippi Code Title 37. Education § 37-5-19

Vacancies in the membership of the county board of education shall be filled by appointment, within sixty (60) days after the vacancy occurs, by the remaining members of the county board of education. Said appointee shall be selected from the qualified electors of the district in which the vacancy occurs, and shall serve until the first Monday of January next succeeding the next general election, at which general election a member shall be elected to fill the remainder of the unexpired term in the same manner and with the same qualifications applicable to the election of a member for the full term. In the event the school district is under conservatorship and no members of the county board of education remain in office, the Governor shall call a special election to fill the vacancies and said election will be conducted by the county election commission.

In the event the vacancy occurs more than five (5) months prior to the next general election and the remaining members of the county board of education are unable to agree upon an individual to be appointed, any two (2) of the remaining members may certify such disagreement to the county election commission. Upon the receipt of such a certificate by the county election commission, or any member thereof, the commission shall hold a special election to fill the vacancy, which said election, notice thereof and ballot shall be controlled by the laws concerning special elections to fill vacancies in county or county district offices. The person elected at such a special election shall serve for the remainder of the unexpired term.
