I am growing increasingly uneasy about a situation that I inherited back in 2008 but which, to my mind now needs to be addressed at some level. The situation is that one of the school's governors is a regular volunteer (one morning and one afternoon) per week in the classroom. I am concerned that there are several boundaries which are being blurred far too often and that this governor is making judgements that they are not qualified to make (for example about teachers performance in the classroom). Is there guidance on the wisdom of governors being in school this regularly when they are not members of staff. Or whether they de-facto put themselves in the same position as staff members on the governing body with the limits to which statutory committees they may be involved in if they are volunteering in school at this level?
