£75 in advance is beyond the reach of many working parents. The threshold for FSM is still quite low. It's the low earners that struggle with policies like these. In my experience (Primary) most parents do try hard to pay at least something towards school trips. Some even overpay. There is a 'hard core' of parents who routinely don't pay but I think this has always been the case. You can't blame the children for their parent's actions or hold them to ransom to make the parents 'change their ways'. It's never going to happen.
