Fixing issues at primary school level probably would address many at high school level.
What I'm seeing with yr3 who have been one of the hardest hit years due to covid (first two years of school where they lost so much time just sitting still) is the knock on effects of that.
The teachers are trying to teach kids who are massively behind, some of whom have had delayed SEN diagnosis, there are shed loads more behavioural issues and then you have the brighter kids who are performing above expectations in someway who just aren't getting support they need either. It's just a total car crash. And thats a school which has good resources and staff.
We are already getting kids who are falling behind, giving shit to those who are bright. At age 7.It's not ok on any level. For either set of children.
I can well see this dynamic is going to be even worse in schools which aren't in such good areas and aren't as well regarded.
Of course that has an impact all the way through.
Why do parents want their kids to go to grammars in the first place? On of the major factors is about behaviour. It's about how less bright kids are being failed earlier on and they aren't getting support that they perhaps are never going to get at home. Support they desperately needed age 5 and 6. Is it any wonder parents either with aspirations or children who are naturally bright, want to put them in an environment where education is seen as positive thing and the kids there generally want to learn?
The elephant in the room here is this dynamic.
Some might argue that bringing back more grammar schools will foster more competition, in groups who probably wouldn't have had the option of the 11+ before. And that in itself might foster a more determined attitude to education in some. I think it may be true to an extent but I'm unconvinced by it.
Round our way, the comp is outstanding. The six form excellent. Arguably there is no need to go for the grammar school. A few parents do choose it because of the academic emphasis and culture. But many many don't, because the comp is good and the behaviour is good there. It's not a barrier to the future.
And social issues and behaviour is very much a socio-economic one, about parental attitudes and good and prompt access and to appropriate educational support when it's needed. If you have a failure of one or more of these, that's where you get the problems that impact children across the board.
In this sense, more grammar schools don't fix that problem. They would however make more of the most pushy and vocal middle class parents who have more money and social status happier. So from that point of view it silences complaints about a system that is failing across the board in the most effective way politically. But its not a solution to a problem. Its a solution to rising concern about schools being overwhelmed and underfunded where they need it most at the least cost to government.
The overall problem here is there has been a decision about the solution without actually considering what the real underlying problems are. I am not sure whether this deliberately cynical or simply due to ideological blinkers. I tend to lean to the latter but its convenient to the cynical.
