I am not trivialising afterschool acticitivies. I think we are talking at cross purposes
I have consistently said afterschool activities are brilliant and valuable, can enhance life and lead to careers. I have also never said you have to have a gcse/a level or degree to pursue these things as a career.
I have said that Gcse grades reflect teaching of gcse content. My son is very high evel in his sport. He didn't have to do any gcse pe content to get to that level, so being at that level would have no bearing on his gcse grade whatsoever. Which is what the study was measuring.
I feel like because the study under discussion was based on gcse grades, you feel like I am seeing gcse grades as the only the thing that is important. I'm just saying that in the context of this study, the gcse is the measure being looked at, and access to out of school curricular doesn't necessarily lead to increased gcse grades, in the same way something in school structured around gcses grades does.
I also dont personally feel afterschool activities are accessible to everyone and I don't personally feel that relying on parents to organise and pay for afterschool activitiies is good at society level for ensuring a wide range of people have access to arts/sports etc. I am very aware I pay a lot of money for music and sports and I would like a wider range of children to access that. One way is through the school curriculum being more balanced in distributing resources or for state school provision to be more even.
