why are you complaining about the governors? op said '2 of the governors' would not listen - what about the rest of the governing body?
it sounds as though there has been a lot going on which you are not party to - and probably won't be tbh. it is obviously something that has divided the governing body as 2 of them left over the appointment process... although this seems to be a while ago now.
is it possible that the teacher who is taking early retirement has had some ddifficulties adjusting to the new head which have been made worse because her husband was the old head? not wanting to be disloyal to him etc? was his leaving amicable?
very odd that the inspection changed so much from one to another, but possibly the ofsted inspectors interviewed the teacher who is leaving, who painted a rather more 'warts and all' scenario of the new head (in loyalty to her husband?) than was strictly necessary? i can see that would get the back of the head and gov body up?
how do the rest of the teaching staff feel? is it just the teacher whose husband used to be the head that has had more than usual problems adjusting?
if it was just the leadership and management that was the problem, rather than teaching and learning in itself? it would be usual to drop a few scores on a change of manangement tbh, however good the new incumbent was...
not suggesting any of this is at all true btw, or wanting to malign your child's teacher, just have had a lot of experience of situations 'behind the scenes' not being exactly as they are portrayed to parents/ community, often for very good reason (ie so as not to tarnish the reputation of a hitherto respected teacher who has found herself unable to work with new management?)
why not volunteer as a parent governor?
