The CESTB is a nine-member panel of constables, sheriffs, judges, county officials and members of the public who set the professional standards for constables throughout the State, ensure every constable is meeting their continuing education mandates, and provides supplemental funding to counties for constable training and equipment. CESTB also investigates complaints against constables.

Section 22-136 of the Arizona Revised Statutes establishes the CESTB. The Board has the following composition:

• 2 constables from counties with a population of less than one million persons - appointed by the Arizona Association of Counties;
• 2 constables from counties with a population of more than one million persons - appointed by the Arizona Association of Counties;
• 1 county administrator - appointed by the County Supervisors Association;
• 1 Justice of the Peace - appointed by the Chief Justice of the Arizona Supreme Court;
• 1 sheriff - appointed by the Governor;
• 1 person who is a board member of the Arizona Multihousing Association at the time of appointment - appointed by the Governor; and
• 1 member of the public - appointed by the Governor.

The Board has several committees that meet to investigate complaints. To ensure impartiality, these committees are designed so that no member will be from the same county as the constable involved in the complaint. Board members serve four-year terms and elect a chairman and vice-chairman each year.

CESTB members do not receive compensation for their service on the Board.
