Throughout this article we refer to the Department for Education's (DfE) guidance on the constitution of governing boards in maintained schools.
Although this guidance specifically applies to maintained schools, your academy may wish to adopt similar procedures. If you're in an academy, check your articles of association to see what your trust's rules are around trustee or governor elections.
You can't discourage candidates from standing
The governing board can't stop or discourage a parent or staff governor candidate from standing in an election, or endorse a particular candidate, even if there are any concerns about how appropriate a candidate is for the role.
Any member of staff, including support staff, is able to nominate themselves for a staff governor position (see page 15 of the constitution guidance, linked above).
