I love the way you dismiss solid research and then make so many assumptions based on nothing except your personal opinion esp when you have no direct experience of state education Xenia.
And as for this comment,
'The children had lots of support at home and at school did not socially mix with children who were different from them and were so unusual in their school they got a lot of teacher attention (which is very unfair).'
Duh, the fact that they had lots of support at home is precisely the point. Middle class kids with support from home WILL DO WELL ANYWHERE.
Private schools take the credit for this while state schools get none. In fact they get blamed for not producing Oxbridge applicants in the 1000s when at the same time they're not allowed to select or exclude or small classes ....
Yes, they also got support from school and a lot of teacher attention. How is this unfair? I thought this was precisely what you wanted!! All children do or should get support at school.
'In the past more children got into Oxbridge from poor homes. It was certainly not a golden age but it was a route now cut off to some children.'
Not true. Not true. There's a lad I'm teaching at the moment who has just got into Cambridge and has just got full marks on one of his January modules and he's been through the state system for his whole life so it is not a route that's cut off.
One thing that's changed is that Oxbridge have taken away the EEE offers which they used to give out when I was at school. They used to give offers based on their own exams and interviews which may have given clever and confident kids from any walk of chance a way in. Now you have to have an A profile and you have to have got As at AS level to be identified as having Oxbridge potential.
It's not the fault of state schools if most of the A grade students have been creamed off by private schools, then grammar schools is it?
And again if you think that students are not achieving A grades at GCSE or A Level because they are being failed by the schools you are wrong, wrong, wrong.
There are so many barriers in the way of a child from a deprived background whose parents are not supportive or well educated themselves (and as Fiona Millar points out a lot of these parents will be the product of secondary moderns or technical schools in the good old days) that they really do have to be remarkable to get good qualifications.
So much of a child's academic success depends on their home environment. Even more so now coursework is such a big part of exams.
This is what you should be looking at and blaming for lack of social mobility:
lack of aspiration from home, lack of parental education, lack of conducive working environment at home, poverty, lack of reading, too much tv, too many computer games, ubiquitous uneducated and untalented celebrity role models ....
