The Constitution provides that a circuit court shall be established to serve each judicial circuit established by the Legislature, of which there are twenty. Within each circuit, there may be any number of judges, depending upon the population and caseload of the particular area.

Circuit Court Judges
To be eligible for the office of circuit judge, a person must be an elector of a county within the circuit and must have been admitted to the practice of law in the state for the preceding five years.
Circuit court judges are elected by the voters of the circuits in nonpartisan, contested elections against other persons who choose to qualify as candidates for the position. Circuit court judges serve for six-year terms, and they are subject to the same disciplinary standards and procedures as Supreme Court Justices and district court judges.
A chief judge is chosen from among the circuit judges and county judges in each judicial circuit to carry out administrative responsibilities for all trial courts (both circuit and county courts) within the circuit.
