Ofsted inadequate

Son's school has just had an Ofsted inspection that shows - achieving academy status AND opening a 'free school' FE vocational centre notwithstanding - that it's gone from a 'good' community high school to being so inadequate, across all four inspected areas, as to be placed in special measures.
All this decay took place against a veritable deluge of supposed good news stories pumped put at regular intervals via email and paid for mailshots. Strange, then, that notification of the Ofsted inspection was by way of a letter handed to pupils to bring home. Being suspicious by nature, I now wonder if they hoped to ameliorate the potential flow of bad news to the inspectors by using the least reliable method: after all, the Ofsted report itself mentions the low number of parental submissions. There's a parents' forum taking place in an hour, where I'm really hoping that serious questions will be answered, particularly regarding the findings of inadequate teaching in KS3 and 4 and the inadequate finding for pupil behaviour and safeguarding. But then again, perhaps I shouldn't expect too much, after all, in the (mailed) letter inviting us to the 'forum', the headteacher assures how keen they are to embark on their 'improvement journey'. From Michael Gove preserve us...

Forum update: Some very interesting questions about lack of quality homework - this is an area that the school has previously said senior management (SMT) were going to tighten up on, but nothing happened. Some parents also very scathing about internal organisation of recent Yr 10 mock exams. The new head did admit, in response to one of my questions, that attaining academy status had not worked for them. Seems to be more a case of being distracted by the 'freedom' of being run by the DoE, as opposed to answerable and accountable to the LEA, that they failed to consider the developments being made by other comparable schools in the locality. She even went so far as to admit that there had been no proper benchmarking undertaken for the best part of two years, so that the SMT were essentially 'flying blind' but happy to do so, given the nice warm feeling of being in charge of their own school and the new FE centre. All crashed down around them now. Gove not such a good replacement LEA after all. Not to worry - it's only our children's futures they're working with.
