Littlefish - there is no body above the GB - they are all powerful.
Remarkably, parents can complain, HT can be dishonest, dismissed for act of gross misconduct (by a panel of three of the school GB btw), have status downgraded from gross misconduct to just a warning (by an appeal panel of three further of school GB btw)(seemingly, the Chair of Governors standing as character witness for HT against the advice of LA - forced to resign by LA shortly afterwards I am led to believe) and allowed to return to school. LA have undertaken within that whole process a thorough investigation of initial misconduct complaint and found that yes, the complaint was upheld in full and that the HT has at no stage been cleared or vindicated. The LA are powerless to act further and parents have no right to know what their HT is capable of and has indeed done. The GB becomes a divisive tool with major infighting (initially 2 of those that dismissed in the first instance remained on GB) between each other (1 of the appeal panel reducing the sanction remains now on GB - 2 others resigned almost immediately!)
Contact with the local MP results in confirmation from the Minister for Education that despite this worrying matter the Secretary of State has NO powers to intervene.
Governors need to be held accountable for their actions however and if the performance of the school appears to be suffering as a result of bad governance then the LA has powers to issue a warning notice to the GB and apply to the Sec of State to replace that GB with an IEB (Interim Executive Board).
18 months on, the LA awaits that signature from the Sec of State, the role of the GB has dissolved into a very public farce, refusing to accept the warning notice despite being urged to vote in favour of it, in the best interests of the children at the school, by both the LA and the Diocese. At least 14 of the GB have resigned (school capacity only around 210), pupil role has decreased from mid 190's to mid 130's. 2 classes are having to be merged. The HT remains in post. The childrens education has become secondary.
So, that's the short answer......and believe it or not, GB's are considerably more powerful in church schools. Don't give up though - I haven't!
EvilTwins - great news, am ever hopeful but I know this HT will not jump...it's just a case of how she will be 'pushed'
