Your school must have a complaints procedure
In maintained schools, the complaints procedure must be published on your school's website so it's available to parents and the school community. You're required to have a procedure under section 29 of the Education Act 2002.
Your procedure should cover all types of complaint you might expect, including those against staff, the headteacher and governors, and serial complaints. Anyone can make a complaint about a school – they don't have to be a parent of a current pupil.
Your policy should have a time limit for a person to raise a formal complaint (e.g. within 3 months of an incident). You must still consider whether to accept or progress any complaint that
