Schools dont organise their students dental appointments, doctors appointments or hair cuts. All of these are actually quite useful things but are considered the parents' responsibility to arrange.
If I started to demand that the school sorted these out for me then I would be considered a very lazy and,dare I say it, entitled parent.
So why is it acceptable for schools to arrange something as frivolous as holidays for students?
It cant simply be about the group element because if so they would be organising students' birthday parties.
Some schools boast about these trips. They include them in their 'sales pitch' to parents. The ski trip to Austria, the geography field trip to China. These trips make good photographs and of course the head will conveniently forget to mention cost. If pushed then there will be some waffle about funds to help the less well off. These statements tend to be long on flannel and short on fact.
These trips use up school resources, the big one being staff goodwill. Because staff have already volunteered for these big ticket trips they will be less inclined to volunteer for the more mundane and affordable trips. Fewer of these less ambitious trips can take place. Poorer students are penalised twice - they dont get to go on the ski trip because their parents cant afford it then they dont get to go on smaller trips because schools dont offer them.
Sadly, according to some posters, this double hit is a useful life lesson. Like the poorer students didnt already know they hadnt picked life's winning ticket.
