OK, so to out my location, I live near Peterborough.
I wonder what Vanilla would make of some of the schools here.
There was one primary school that was identified by the Daily Mail in one of it's ''shock horror'' stories as being a school where EVERY pupil had English as a second language. Here is the coverage from both the Daily Mail and the Guardian. It's worthwhile reading both, by the way, as they are both generally supportive:-

.
A lot of these pupils would never be selected for grammar schools - if they existed here - simply on the basis of their level of English. However, if you look at their maths ability, a lot of them are really really good.
There is a local faith school that is very good. Even on Value Added scores it comes out very high, especially for high attainers where it statistically significantly outperforms. Incidentally, it is also the nearest secondary school to the primary school mentioned above.
But, if you don't have evidence of CofE worship - and it is specifically CofE any other Christian denomination isn't good enough - for 5 years prior to entry then you will not get in. Unless you are a good enough singer to be a chorister.
So, all the very bright children, both British and other nationalities, whose parents did not have the foresight to start attending their local CofE church five years previously has got little or no chance of going there.
The reason I mentioned ''very bright'' children is that this school does statistically significantly outperform when it comes to Value Added measures for high attainers who enter the school at 11.
Two of the other schools in the city significantly outperform on Value Added measures for low attainers but fail high attainers.
My personal view is that a large part of the problem is down to low expectations from the teachers.
In the examples above, I would suggest that the teachers at the faith school are pushing high attainers to achieve their best but are, relatively speaking, ignoring the rest.
Likewise, in the schools that are outperforming in motivating low attainers, I would suggest that the teachers are really not stretching the high attainers enough.
Both schools could learn from each other about the best practices in different areas from each other.
Sorry that this was a very long rant. I guess that I'm saying that I'm really anti selection but that there is also room for improvement in how comprehensives are organised.
