So. just to clarify, you want to go back to where there was no choice and you automatically went to your nearest school?
Yes, Badbad.
You want to scrap all selection, i.e. no faith schools, no grammars, no schools with specialisms (such as for sports, Maths, languages, science, etc.).
Yes, I would scrap all selection.
there can be no other way to offer every child the same opportunity, other than to have a massive network of comps all doing the same thing.
There might be slight differences, based on demand, from the local community, on what individual schools offered. However this would change naturally as communities changed. An influx of new people, with new, differing needs, would mean the school had to change what they offered to suit. The schools, being truly comprehensive would have be responsive and dynamic to meet any changing needs.
That sounds like a massive U turn after years of the mantra being "choice" where you had the freedom to send your child to a school specialising in Maths if they were gifted in Maths or sports if they were a talented sports-person.
Is that really what you mean?
YES!!! No more pockets of individual expertise. No postcode lottery. Responsive dynamic comprehensive education.
