Someone asked if I was paying for results and if not what am I paying for. It's a huge huge range of things. One point that is coming out of this thread is how important in the workplace good English is in so many different industries. In my own profession you can divide CVs up into those who can spell and use capital letters and proper grammar and those who cannot. Someone said the state grammars were better than the private schools for this. I do not agree but mostly because most of the country has no grammar schools. In my own area as a child they were abolished in 1970 so they are an irrelevance except in a few areas. It also marks out non English speakers too and if you don't speak English at home one way really to help children is ensure they do learn to speak and write English properly as even if they are AAA in everything if they write badly employers will put the CV into the bin.
I don't think some state schools are rigorous enough about grammar and spelling and some of the teachers may not even speak correctly (of course this is quite a generalisation).
So what did I buy, what do I buy? All sorts of things. I quite like the segregation of the clever from the rest. I like the segregation of disruptive from those very engaged with work. I like the segregation from parents with whom I might have nothing in common. I've enjoyed singing difficult choral music at various schools and I am not saying the parents at a comp cannot sight sing to the right standard but those local schools seem to have less a parent might enjoy on offer. I've enjoyed schools largely without graffiti and litter. I like fields and lakes. I don't like boarding schools and would not use one. So I am buying separation in a sense just as the parent who buys near a comp for the rich in Surrey is buying segregation by house price but they are not honest enough to admit it in many cases.
I am buying the chance for my chidlren to study in a meritocracy as they will have to do in the world of work where you compete like anything to get in and then seek to hold your own when you are there.
I buy a chance to work beyond the syllabus for a rounded education free of the national curriculum. I buy a place where children might be treated in a way some of the supposed protections of state system and strictures might not appyl. I buy more chance for them to take pysical risk. I buy more chance they may be hurt in difficult dangerous activities.
I buy that boys can be educated a boys' schools and girls their own. In other words I buy segregation by sex.
I buy an entry on their CV which might be remarked upon even when they are in their 20s as people would say gosh that school, it's really hard to get in there, they must be quite bright.
An important thing I buy for teenagers is a peer group where everyone has very very high expectations , where not working is not the done thing. I buy the chance for 12 year old boys to sing chuch music in latin without being teased by their peers.
I buy a massive range of hobbies available to them so that in later life they pick those things about which they are enthused. I want them to have chances and opportunties.
I hope I can also buy an environment where the teachers and others do not have particularly bad English.
I buy the chance to be a customer/consumer with all the free market advantages that usually bestows on the organisation concerned.
Lots more but I'm trying to earn a crust and it's quite busy.
