I think some people do find it hard to realise that for some children, for a multitude of reasons, the only way they experience some things is when schools are able to offer them.
We have a DC in a specialist school and he gets absolutely none of these educational visits or even fun trips - or any on-site enrichment (because they let him choose to play computer games during his weekly enrichment session so he doesn't choose anything else).
We take him to the beach, the theatre, the cinema, swimming, climbing etc. but there is absolutely no requirement or any will AFAICS to provide this for any child who "doesn't want to" aka is too nervous or who will take an easy option when given the choice.
They don't have any clubs of any variety, music, choir, sports, hobbies, nothing like that.
In his last school (a PRU) they had external providers for music and sport and he did engage a bit with them but he wasn't allowed to go swimming with school and they provided nothing at all other than that. His first school was on the same road and they took children for simple walks, as well as coach trips to the panto, to see Father Christmas etc.
And no, "but risk assessment" isn't an excuse. He was fine with a 1:1 on all the trips he took in his first school, and they had 1:1s for all the children who needed them. If children are never taken out, they will become anxious about going out. This, in itself, is a risk.
Given that children in poverty are massively over-represented in specialist schools, I think this is shameful.
