target market of anxious parents facing an opaque process, anxieties whipped up by apocryphal stories and chinese whispers in the playground
It's this isn't it? Bolstered by regular newspaper stories about super-tutors, unfounded scare stories about 'state schools', (as if schools are homogeneous) and a deeply competitive culture we have at the moment.
I was a teacher and when we began working overseas as my children were about to begin school, 16 years ago, one of my major reasons for delight was that I could, like Copthall, avoid the mania, which I knew would be really hard to resist when in the middle of it. It is far easier to see the woods for the trees when your children are coming out of the other end. The differing pathways and attitudes of an international community also help one to see there is more than one way of doing things, but I really sympathise with people in the middle of a competitive areas whose children are clever but not shoo-ins for these schools.
I have young relatives who attend a provincial 'super-selective'. Their tutoring was short and sensible, but, bad luck aside, it was known from CATS type scores that they were very likely to succeed. It is harder on those who are borderline and I think an idea that is current that 'IQ can be improved' has an effect on the idea that more tutoring must be better as does a general mistrust of the education profession.
An oft quoted opinion that I am not at all sure about is the one about over-tutored children struggling. If a child gets through a selection process then fails to thrive, then it suggests the tests and the assessment of them are inadequate. More importantly though, I think it is a real failure on the part of the school: a child who can do sufficiently well to be selected on the basis of a test looked at by teachers can be supported without too much difficulty thereafter.
At one time, my children attended an overseas school which could be compared to a 'super-selective' in terms of intake and outcomes. Teachers' children did not have to pass the test, nor, I suspect did some others for community/social reasons. They sometimes needed extra support from school but they were never described as failing or struggling and they inevitably did well in the end because the school took responsibility for them. Some of these school in the UK don't as far as I can tell.
Like Yellowtip, I am also interested in why provincial schools with a far smaller pool from which to choose and a less febrile attitude in the community seem to do well in a kinder way than some of the schools in metropolitan areas with a huge pool of able children from which to choose.
