Are the ordination-statuses in this list exclusive and comprehensive?

I'm constructing a survey of Anglican worshippers in England. One of the questions asks about _ordination-status_, with the following options: * I am ordained * I am a curate * I am a licensed lay-person * I am an unlicensed lay-person For worshippers in the Church of England, are these categories: * **comprehensive** (_everyone_ is described by _one_ of them) * **exclusive** (_no-one_ is described by _two_ of them)?
