More details.
There are 5 government funded secondary schools in the area, and 3 fee paying.
Our catchment area school is dire and came to our school claiming they can help your disadvantaged child - when asked about normal children - oh we have them too or words to that effect.
The best two schools of this type are both religious, 1 is Catholic, one is church going CofE (requires references from the vicar), since I do BDMs no hope

. The other two schools, one is the other side of the city, and the one we did choose for Emma-Jo is the nearest, middle best, mot in catchment area and very heavily over subscriibed. It is most east side parents first choice if not church going and it is church goers second choice.
Anyhow we found that the local fee paying grammars (one all girls, one merged from a girls and a boys, and one a bit posh) all offer bursaries, for clever children from not well off families. The penguin school we didn't notice until last week!!!! (taught by penguins - see Blues Brothers). The other two Emma-Jo passed easily but the more exclusive school offered 1/3 discount. The larger merged school offered a lot more, my daughters teacher went to that school so I think that helped.
To be honest it is wrong that I have to do this, our children are supposed to go to the second worst school in Worcestershire, and the over subscribed school has to cope with TWO large new estates as well.
20 years ago the school we won was free!
As to mixing in, none of mine will go to the sink school there is rapant bullying and they are already picked on a bit, the boys do tend to stick together but I worry that if they went to sink school they will end up as bullies them selves.
But I have 3 years to wait before worrying about them.
