Reshuffle of classes, child distressed, parents rights?

[ProudMummyofbg]

My child's school has decided to reshuffle the classes and he is been separated from his best friend. He is absolutely distressed about it and so we are; but school says he is fine and doesn't show any anxiety at school. My son is diagnosed with high functioning autism and he is emotionally very unstable.
We spoke to school about it and explained that his only social link has been taken away from him. We requested to join them together as the other child's parents are also willing to do so. But school is dismissing our points.
I was wondering what our rights are as parents in this regard.
Thank you for your advice.

This is not your call to make and you don't get a say on class groups. I agree that they may have been separated to stop over reliance. The school will be trying to keep all children's best interests at heart. Naturally as the parent you'll be most interested in your child.

I wish ds's school would reshuffle as he is far too reliant on one friend who isn't very nice to ds and brings out the worst in him. We asked. It's not happening.

Schools often can't win.
