'Entitlement' and 'best' are vague terms and UQD wants us to say what we feel about them. They mean different things to different people.
To respond more directly to UQD's qu.s.
'If so, why?'
I am 'entitled' to choose any school I want for my children so long as they meet its entry requirements.
In order to meet the entry requirements of the 'best' schools my kids would have to be either or all - lucky, rich, Christian, academically gifted, or rather have parents who were.
So 'entitlement' to get to a good school in today's climate in some ways is like 'entitlement' to buy the 'best' car or the 'best' house. And just because I can (afford a private school or good state school) doesn't mean that I or my kids are better or more deserving than anyone else.
'Define "best" '
Impossible. And actually I'm not at all (probably like the vast majorit of parents with the exception of Xenia) interested in the 'best' in terms of the top performing nationally. Not at all. I want a school which achieves good results and where my kids will be happy,supported and challenged. Full stop. To find this school (which I have) I looked at my local schools (league tables and physically and dp and I have worked in quite a few of them) and then went private.
'Does this apply also to people up the road?'
My next door neighbours are 'entitled' to make the same or different choices that I have. They probably can't afford to go private. I think they send their dcs to a church school which as an atheist I can't. Their dcs are no more or less deserving than mine.
'Does this apply also to people in different social classes?'
Ditto
'Is there a middle-class sense of "entitlement" to the "best schools" in this country? '
The middle classes are no more or less entitled than anyone else they are just have more money, education etc to exploit the choices availabe to ehm. And choices ehich the govt has made available and promoted actually.
'Is the problem that we have such a variation in standards of schools across a supposedly comprehensive system?'
Unlike you apparently UQD I don't see that there is a 'problem' in standards any more than there ever has been. I agree that there is too much polarisation though which means some schools sink and some fly. Most are somewhere in the middle in terms of their A-Cs which itself is made up of some extremes (students with 9 As and some with none and some in between).
'Is it people playing the system, moving out of catchment, "getting faith" etc, and making themselves part of the problem and not part of the solution?'
Yes, this is hardly a revelation!!
'Or is the issue simply one of being too obsessed by the schools that do well in the league tables and/or have a nice uniform?'
Nobody sensible chooses a school for its uniform or for snob value. Most parents choose the best school they are able to in line with their understanding, income and principles. No parent should go by results alone either but GCSE and SATS results do reflect otehr aspects of the school and can tell you whether a school is improving or not. A school which is at the bottom of the league tables is highly likely to have problems which are not just to do with having a lot of not very acadmic students e.g with behavour, with recruitment. Educated parents are able to 'read' league tbles and read between the lines.
