I know a lot about dyslexia, of course. I don't think either of the mistakes I highlighted would raise any flags.
And, for a dyslexic, who will find a reading based curriculum a struggle, whatever support is put in place, surely missing school for holidays would be even more of a mistake.
I have apologised. Not sure what else I can do.
However physically demanding skiing is, it is not a well rounded education. It might contribute to PE, or even to emotional well being. However, if you want to pass an exam in, say, Physics, it is no use at all.
My children went skiing with their primary school btw but it was a whole school activity, part of their curriculum, and they missed no lessons. If you want skiing as PE, move to Scotland.....no need for term time holidays.
