"Staff governors" (other than the head teacher) are elected by the school staff and must be paid to work at the school, directly by the school (that is, not under an external contract such as catering or cleaning). At least one staff governor must be a teacher, and if there are three or more staff governors, at least one must be a member of the support staff. If no member of the appropriate category stands for election, the vacant place can be filled by an elected person from the other category (i.e. if no teachers wish to become governors, all staff governors may be support staff, and vice versa).
