"I agree with you OP. I wonder how many people who reject them have ever been for a look around. "
I would have loved to have looked around my local state primary when my child was 4, but unfortunately I couldn't, because the school secretary told me that the Head was far too busy for that kind of thing, and they didn't see a need for an open morning either because it was 'a waste of time'.
The school was one step from special measures at the time, and I would have been prepared to give it a go, working on the basis that a middle class child like mine could probably do well anywhere, but strangely, the school's attitude put me off somewhat.
The only other options open to us were to move to somewhere cheaper in the same town (equally bad schools), or out of town (never see my husband who would have had to commute) or move to a more expensive area with a good state school (but we couldn't afford an £800k house) or put our children into an independent school (have almost no disposible income but stay in our house, and spend time together as a family).
Things have changed a lot in this area now, and there are a number of good state schools. I meet some of their staff through a voluntary group I work with, and they are lovely, committed people. If I have a 4 year old now, it would be a different story, but that wasn't how it was when I was choosing for my child.
The thing that drives me wild about this debate is that there are two contradictory views which generally are held by the same people.
One view is that it is these nasty sharp elbowed middle class types who cause all the trouble in state schools - they get the 'best' places because they are pushy and can afford inflated property prices, the want to have cake sales, their children are all PFBs etc etc.
At the same time, there is the view that failing, ghettoised schools are like that because the local middle class parents don't send their children to the local school but use the private system or church schools instead. Those pushy middle class families and their children are perceived as a factor in raising standards.
Now, you can't have it both ways - either my middle class values (hard work, thrift, valuing education, tolerance, kindness) are good, or they're not. Until those parents who despise private schools can make up their minds on that one, my children will be staying where they are.
