You’re misunderstanding what I’ve said.
You seem to think that people should only do music or sport or art with a view to entering competitions. A very limited mindset.
I don't think they should only do those things with a view of competitions.
I think it's reasonable that nurturing those who demonstrate promise in those fields is a good thing.
Since we’re being facetious, I’ll lower myself to say that regarding, for example, the Maths Olympiad, I would think it more important that every child in the school learns Maths rather than that one or two train for the Olympiad and the rest do no maths at all.
Not comparable as all students learn maths in their maths lesson, and a mathematics enrichment opportunity can be there for those who show promise.
Same for music.
Students get music lessons as part of their curriculum, and then there's musical enrichment for those who show musicality.
Regarding sports, I’d rather see all children achieve a good level of fitness and enjoyment of sports than that ten are chosen for a team and the rest do nothing.
Again, students have access to PE in the curriculum.
The gifted few are perfectly free to enter competitions and pursue whatever they like to a higher level - if not at school than outside of it.
This is where you're missing the point.
You're viewing it as the gifted Vs everyone else.
The way I see it is the very gifted will already have a range of enrichment from home.
There's a wide range of children with an aptitude for different areas and staff can see potential in who can be nurtured in school enrichment and have access to opportunities they'd not otherwise have.
By focusing lowering the expectations and opportunities, and lowering the exposure to arts, music, sport to the bottom of whoever wants a go, it ensures that all the children who have potential and have demonstrated an aptitude for an area don't get a chance.
What we end up saying is that for the parents who can afford private schools, who can afford lots of tuition, who can afford to be a member of several out of school sports teams, THEIR children get to excel and develop their talents. But for all the other children with talents and aptitudes, they don't get to nurture those gifts because your average state school should focus on general fitness, getting people to scrape through their exams, and a limited diet of music and drama in order to pitch enrichment for those who don't demonstrate an aptitude.
Not everyone is good at everything. If I had to choose between helping nurture the talent of 45 students who've shown an aptitude Vs the 2 who've shown no aptitude but want to show up and their parents are moaning, why should 45 children lose out?
