County government includes other elected and appointed officials who serve concurrent four-year terms.

Major elected officials include the chancery clerk, who manages records and administrative tasks for the supervisors and chancery court; the circuit clerk, who handles election administration duties; and the sheriff, who functions as the chief of county law enforcement.

[6][5] Through evolving constitutions, counties are granted police powers, administrative duties for transportation infrastructure, and election scheduling for vacacines in county offices.

The Board of Supervisors are mandated to additional duties as defined by the legislature.

[2] Prior to 1988, each supervisor independently managed roads and bridges in their assigned area, and would allocate money at their discretion, subject to restrictions in state law.
