Not surprised to see this petition.
I have had a child in Graveney 6th Form and in another favoured S London Comp, and I have worked (not as a teacher, as a visiting project) in other nearby S London Comprehensives.
I was shocked by the segregation at Graveney - the strong middle class white cliques in Extension and top sets in 6th form getting favourable focus and treatment. There was only one black kid in one of my DC's classes, and this is in S London, FGS.
My Dc was shocked by some really blatant events. A black student disappeared immediately following a drugs discovery (fair enough), a white student was given a minor sanction after an equivalent offence.
Some years ago there was a major incident, police called to a mass fight in the playground. Years later there was ongoing pupil unrest about the favourable treatment given to a white student who caused serious injuries to another pupil with minimal sanction - and then continued in the school feeling free to make racist comments.
The class issue starts with the families (including from miles away) tutoring at great expense for a selective place. These are 'super selective' - they go to the top scorers, not just those who pass at a certain level. So those who can afford tutors for bright kids are at a strong advantage.
Then, perceiving it as the school where aspiring m/c families go, other economically advantaged families rent property nearby to get the remaining places that are given on distance. The school does nothing about this.
So the intake is white m/c way out of proportion to the local community. And the top sets are full of these kids.
Class divide becomes race divide - that is the way institutional racism works.
My Dc was shocked at the lack of diversity in the top sets - totally different to the school they did GCSEs at, a school which is high achieving with an excellent 6th Form too, but diversity wise the top sets are in ratio with the school and with the local area. Not the case at Graveney.
Also my Dc was shocked at the way the extension classes are supported and celebrated (great, of course) but middle and lower sets pretty much ignored and students not so well supported. This had not been the case at the former school where all kids were supported to do as well as possible.
Plus it is an 'old school' sort of school, staff and SLT been there ages, all cosy with their reputation.
I was impressed with the education on offer, but not with the communication from the school, the cliqueyness, or the massive drug use fuelled by lots of pupils with lots of money and liberal pushy parents in the media who are cool with their teens smoking dope at home. And the rest.
It is a good school, teaching is good, behaviour is good. Projects such as STAGS and other opportunities are ambitious. But this issue is real. And I hope that the school will take it seriously, be brave, be open and use it as a moment to make some real changes.
However.....the school was due to meet students to discuss these issues, yesterday morning, I think, or Tuesday. They then cancelled the meeting because they realised they had organised it without a Safeguarding lead present, and hadn't checked availability, so cancelled. The young people involved are upset and frustrated, feel this is typical. This can't be treated in a tokenistic manner.
