I think the problem with the proposed banding is that it won't be used to help underachieving children, it will be used as a stick to beat the children with, who are probably underachievers through no fault of their own, whether it's because of lack of support at home, through learning difficulties, through not performing well under pressure.
Too many people lump children together. You cannot fit all children into one mould, as they are all different, with different capabilities.
Not all children are academic.not all adults are academic.
Of my children, ds1 is highly unacademic, I suspect he would be in the bottom 10%. However, he is very practical, and at 12, could probably take an engine to bits and put it back together, yet he is judged on his academic skills alone, and feels crap about himself because of it. When he leaves school, I imagine through his practical skills, he will have no problem getting a job.
Ds2 is quite academic, probably not top 10%, but definitely in the top quarter. He gets more encouragement than ds1 ever did at school, because he fits the mould and the curriculum suits him and the way he learns.
I feel so sorry for children who lag behind at school, particularly primary school, as there are no rewards for skills that aren't academic. It's no wonder so many children disengage from schooling. By banding children at such an early age, I believe it will be disastrous for those who come out on the bottom.
A country needs people across the spectrum. It needs the drs and lawyers, the outstandingly clever scientists, but it also needs those in jobs that are not valued by society, which are often carried out by those that have not done well academically.
I listened to the Jeremy Vine show, and heard the following quote from Albert Einstein - "EVERYBODY IS A GENIUS. BUT IF YOU JUDGE A FISH BY ITS ABILITY TO CLIMB A TREE, IT WILL LIVE ITS WHOLE LIFE BELIEVING THAT IT IS STUPID.?
I agree with this wholeheartedly.
