combustiblelemon - the kids are being stretched. I would say the VAST majority of so-called G&T children are being well served by decent differentiation within a class. A teacher will always differentiate between children, and will give extension work to those who find it easy. The very (and I mean VERY) occasional child who is not well served by this may need an IEP. But these children are SO few and far between, I'm not sure a government initiative (or a chat forum topic) is going to help them particularly.
I've posted this before on here, but I have known a handful of children who I would describe as being 'truly gifted'. And I've known of one other. Let me tell you about them;
Child A and B - identical twins. I used to babysit them and be ASTOUNDED when at age 5 they had a grasp on the A Level Physics I was doing. They had also designed and made cars powered by elastic bands. Everything about them screamed 'amazing brain'. They were stretched sideways - so rather than doing GCSEs and A Levels early (which they could have done with their eyes shut tbh), they did extra GCSEs, extra A Levels. They did more sport, learnt classical languages and instruments. They are extremely well balanced young men now, one went to Oxford, one to Cambridge, one did medicine, the other law. Both got prizes at the end of their 1st year for getting the highest marks in their exams.
Child C - very gifted musically, but needed to learn social graces. Not because of his 'giftedness' but because he had virtually no bringing up - he had pretty well brought himself up. I taught him for 5 years, he got a scholarship to the Royal Academy, but also managed to 'round' him off, so that he is now able to 'live' with others and has a very good social life. This really wasn't anything to do with his 'gift' - it was all about his lack of upbringing.
Child D - all round 'clever' child - good at most things. Slightly quirky, but respected by his peers for his intelligence, and they actually liked his quirkiness. Again, stretched sideways to keep him 'normal', went to Oxford to do maths, won prizes for exam results there.
Child E - muscially 'gifted' child. Amazing at composition - at early age (12) had orchestral piece performed by London Orchestra in Royal Festival Hall. Pulled out of school to concentrate on music, ran away at 16, gave up music completely, cut off ties with parents. At about age 30, tentatively returned to music, but in a teaching context in a school.
The stretching sideways is definitely the way to go imo - if a child ISN'T being fulfilled by the curriculum then see if they can do something different as well - maybe learn a bit of Latin or French, or Russian, or an instrument, or do a project on something interesting and unusual.
If a child is a very 'good' reader, it still doesn't mean they are emotionally ready to tackle the hard texts - similarly, in music, a brilliant technique does not mean you can 'meaningfully' perform some of the more emotionally complex music - I would much rather hear a younger musician performing Mendelssohn than Rachmaninov, because in Rachmaninov they are probably simply playing their teacher's interpretation, in the Mendelssohn their youth is on their side!
