Each congregation has a body of appointed unpaid male elders and ministerial servants. Elders maintain general responsibility for congregational governance, setting meeting times, selecting speakers and conducting meetings, directing the public preaching work, and creating "judicial committees" to investigate and decide disciplinary action for cases involving sexual misconduct or doctrinal breaches. New elders are appointed by a traveling overseer after recommendation by the existing body of elders. Ministerial servants—appointed in a similar manner to elders—fulfill clerical and attendant duties, but may also teach and conduct meetings. Witnesses do not use elder as a title to signify a formal clergy-laity division, though elders may employ ecclesiastical privilege such as confession of sins.
