The Order of Precedence is a ceremonial order of rank or preference, especially as observed on formal occasions. Within the SCA individuals with different awards are given a different level of precedence. Individuals with the same awards are placed in the order based on the dates their award was received.

Below is a complete list of how the Order of Precedence is determined, this is only meant as a quick reference, for more information, please see (link offsite):
