The composition of a House of Bishops varies from jurisdiction to jurisdiction. Typically, they consist of archbishops and/or Primates, diocesan bishops and sometimes suffragan and coadjutor bishops (who may, in turn, be elected as a fixed number, as happens in the Church of England). Houses of Bishops of Anglican Communion provinces are typically chaired by the Primate, Archbishop, or Presiding Bishop of the province, while in some provincial subdivisions of a Communion province, a House of Bishops is chaired by a provincial metropolitan.
