Yes, I know. I linked to a research paper above that highlighted the lack of evidence with regard to academic selection producing better results. I'm quite capable of doing a Google search, I was just interested in knowing which countries' systems you thought that we should emulate.
You say that you've proposed alternatives above but I can't see how your suggestions would improve the system. You want more grammar schools with more fluidity for late bloomers but less academic, more practical content for the kids who go to the non-academic schools. Not really sure how late bloomers would transition between the two if they are following such different curricula.
Then you've talked about having "proper assessment" processes but you have been very vague about what that would actually entail, other than mentioning that it would involve teacher assessment, which has previously been shown to disadvantage kids from less privileged backgrounds.
You've made reference to different learning styles, but you seem to be working on the assumption that kids with similar level of academic ability will naturally have similar learning styles, which almost certainly isn't the case.
And you've highlighted that the current approach is failing kids with SEN but you haven't mentioned where they will fit in to your new system. And what about kids who are "twice exceptional" - academically gifted but also having SEN. Where will they fit in?
All in all, I don't see any real workable proposals that would contribute to better outcomes for all children, nor that would lead to greater social mobility. I just see a push towards segregation that would primarily end up being along class lines. Not what I want for my own dc or for anyone else's, thanks.
