Yes, they do. They have to make the request and usually write an essay/paper to explain why they believe they should be granted the exemption. The bishop, in conversation with the Synod Council and Presiding Bishop, makes the decision, which is final. Sometimes the exemptions are granted, sometimes not. Also, I would say that there are certain synods where the exemption is almost guaranteed and other synods where the bishop is really opposed to granting any exceptions. But, however the ordination occurs, all newly ordained are placed on the one clergy roster.
