In most covens, the process leading to membership and initiation requires a period of study and practice, often a year and a day. Sometimes, to honor leaders of different covens or help establish friendly bonds between them, initiations will be given without such training. That is, a Witch of tradition 1 initiates into that tradition a Witch from tradition 2. In turn, the Witch from tradition 2 initiates into that tradition the Witch from tradition 1. Theologically, this allows covens to work with the specific deities of the other coven. It also allows a High Priest or High Priestess to officiate at another coven. This can be valuable if the person regularly working in this role becomes ill, leaves the coven, or dies.
