The "general assembly" (or general synod) is the highest court of presbyterian polity. Each presbytery selects a number of its members to be commissioners to the general assembly. The general assembly is chaired by its own moderator, who is usually elected to a single term. He or she is addressed as moderator during meetings, but like the other moderators, their position has no bearing outside of the assembly meeting and affords him/her no special place in other courts. He or she presides over meetings of the assembly, and may be called on in a representative function for the remainder of the year.
