It's almost a 3 tier system of education where I live. 4 private schools, only 1 of which has a really good educational reputation, the others I thinp parents send thier kids there for swank reasons.
Then 3 really excellent state senior schools, in the top 10 in the county etc. Then 2 really terrible state schools.
So, if you are loaded go to the private ones, well off enough to engineer it to live in the catchment area of the good state schools, you're sorted, if you are poor/live in an undesirable area, you are stuffed and go to the poor schools.
It's horrible. Where I moved from in Devon was completely different, only one school in a radius of 20 miles, so everyone (unless they really were rich, and there weren't many of those) went to the same school. Which wasn't the best school in the world, but had a more varied social mix than the school my dd is at now.
The devisiveness of the schools where I live is very apparent to the kids as well. Inter school matches are a bit of an eyeopener, private schools call the states scum, good states call the poor stated pikey etc. It's like the school version of that Two Ronnies class sketch where John Cleese and the Two Ronnies are all stood in a row.
