Getting rid of Grammars in most of the country was the worst blow to social mobility in the UK in living memory.
Luckily we still have a few in Essex which both my kids benefitted greatly from.
They were retained across Norn Irn when they were killed off in England, but once Blair put former IRA murderers, who are all devout socialists in Govt, and they then took over education, they started to dismantle the system for purely dogmatic reasons.
A great shame.
We still have some in Kent, including the one I went to. One problem is that grammar schools - selective schools is the current and surprisingly accurate term - were meant to be only one part of a
system, and some of the other parts are long since missing. All they do now is suck money and talent(pupils and teachers) away from other, bigger schools.
We shouldn't forget that grammar schools were meant to provide appropriately educated school leavers for white collar jobs with the top few percent sent to university, in the same way that technical schools(the biggest missing part) did for prospective tradesmen. Both the boys(they're almost always single sex, which is another outmoded decision) grammar schools here were started as that: one to teach maths for new naval officers(after 300 years it's still called Sir Joseph Williamson's Mathematical School and known as The Math) and what is now Holcombe Academy(another badly implemented, expensive and generally questionable idea) that was Chatham Technical High School for Boys when I started there in 1981. It had been founded to do the same thing for boys expected to get apprenticeships in the dockyard. By that time it was a grammar school in all but name, which was changed in summer 1982 to Chatham Grammar School for Boys - there was already one for girls.
Another problem is that pupils for these schools are selected when they're ten years old, and I doubt you'll find anyone who would approve of such deliberate social engineering of children at that age in any other way. That includes me and the other 3 members of my immediate family who all went to grammar schools. Their time has gone, but instead of improving the remaining schools and the education they provide, the time, effort and money had been spent on increasing the middle management and bureaucracy. The NHS has suffered similarly
The Labour push to send everyone to university, even for education that was better done on the job or as traditional apprenticeships, has done the education and employment of school leavers no favours either.
