My DC's go to an excellent school (if you go by the SAT results).
They are intelligent, sociable, well mannered, confident, polite and a whole handful of other complimentary adjectives.
As they work hard in school DP and I see it as our duty to have as much fun as possible outside of school. i.e. we don't do extra work or have them tutored and that is a very common attitude amoungst the parents at our school.
It is our school i.e. there is a lot of input from the parents. It is a very middle class school, however because it is a faith school there is a fantastic ethnic mix (we're close to a big city). There may not be a vast variation in back ground but that suits us!
That's not to say there isn't a huge variation in peoples circumstances (MC means a huge percentage of the population as other threads have discussed). However, there is a common attitude of being at school to learn, that learning is fun (and the teachers at our school are excellent so it genuinely is fun) and giving the children drive (which you need to achieve your goals in life whatever your background).
The school does not skimp on extra curricular activities. In fact they go out on a limb to provide additional activities and has strict code on how they treat themselves and other people (emphasised as it has a link to a church).
It is true to say that due to the middle class background of the school the parent helpers and TA's tend to be ex or highly qualified teachers and it is they who bump up the SAT values.
One of the TA's has introduced a workscheme that has seen the school rocket up the SAT's tables, this is not a coincidence. Prior to having children she was the deputy head at a well regarded senior school and was our head teacher's boss at one point prior to that.
Her input for a couple of hours a week makes a massive difference to every child in the school.
My gripe with all this 'shame on you for sending your child to a school with good SAT results' attitude that some posters perpetuate is that
a) it's a massive generalisation and doesn't take into account individual schools
b) it makes a link of good results=stilted social growth of children because they spend all of their time doing numeracy/literacy that I'm not sure is true.
c) it sneers at being middle class which is just rude.
d) it implies that you can't be middle class and not be white, which is both incorrect and slightly racist
e) it assumes that all of a childs social ability comes from school and so to be at a middle class school means you don't socilise with people from different social situations to themselves. It doesn't take into account the childs cultural heritage and family friends.
f) it assumes that parents absolve most of their parenting/education of their children to the teachers and the school. Sure they're there to teach my child, but I see myself and DP as the primary educators of my DC's
Our school may be the only school that is truly amazing and yet does so well in the SAT results, and in so being, is the exception that proves the rule, but I have to tell you, it is possible and our school is an example of it.
