Also I'm going to take major issue with one of your premises.
Correlation does not mean causation.
One of the biggest problems I see in schools currently is the management of mental health and ADHD. Schools are not positive environments for many kids with adhd or mental health difficulties.
Privileged areas parents are more able and more likely to be able to go privately for quick diagnosis and treatment.
Deprived areas that may well not be possible. They may be reliant on CAMHs and the NHS which takes years
In turn that will have an impact on behaviour in school which will make a positive ofsted that much harder.
I can walk into a classroom in a deprived area and often spot 2 or 3 kids clearly with adhd struggling in a classroom environment without an EHCP or even a diagnosis on the system.
That's before you even start with whether a parent may agree or even approve of a diagnosis.
But that isn't ofsted's fault. They arent necessarily causing that deprivation. Ofsted are may just be reflecting the reality of the challenges of the area.
But let's remember Caversham is not a Deprived area.
And we're not talking about an ofsted that was failed on behaviour management or teaching.
It failed for basic safeguarding. No school anywhere should fail for basic safeguarding.
Least of all a nice school in a good area with limited challenging behaviour.
