This doesn't paint your school in a good light.How can you say you love the school?
I wouldn't want my child in a school where this was the view of him.
He is a failure at 6?
I hope your view of him isn't shaped by this as lots of children start slower and then excel.
The C4 genius of science programme the other night was a real illustration of this which I'll quote from just to perhaps give you something to consider.
Stephen Hawking, one of the scientists profiled, learnt to read late and did not like conventional lessons.His handwriting was 'terrible' and he was not competitive, said his mother. He was often near the bottom of the class.But by the age of 10, he knew he wanted to be a scientist. He liked designing complicated Meccano models, and at the age of 16 he and his school friends designed and built a working computer out of parts of old machines.
Perhaps this is your son who was been written off by his school.Perhaps not but all children cannot be categorised.
I would guarantee the prep results are excellent if they cherry pick children, dropping them as needed.
My dd(June) didn't start to excel to beyond age 6.She is doing very well.
We can afford private but choose state.
Dd's school friends are similar to her from good families (different economic backgrounds)who expect their children to do well and support them with several of them who are very academic,others that excel at music or art and really the family support is the main factor.
Why do you think state school won't support your dd? Again it may just be maturity that is helping her and she may level out with some younger children in her year group.
Or she may be gifted and again a state school with your help can accommodate her.All depends on the individual school and the value placed on learning at home.
I would move them both to another school (state or private) and get a tutor to help your ds,give him some confidence and reinforce what is learnt at school(£25/hr average here) although I do think at this age you can do alot yourself as a parent to help if you use the available resources.
State schools do not produce rough individuals just a normal cross section of society with some extremely bright cultured individuals thrown in!
