DDs secondary school (in Wales if this makes makes a difference) organises trips, during term time, with limited places and at a cost of several hundred pounds. Obviously only a few children get to go and the rest have to stay and do lessons as normal.
I'm curious as to why this is allowed. Presumably the trips are not considered essential to the curriculum (the one coming up next is an adventure holiday) because if they were then surely all children should have the opportunity to go (I understand that to be the legal position anyway). So... how do schools square it that some children can miss a weeks lessons for a holiday but the rest can't?
