We can only raise the cost of an educational trip or activity through voluntary contributions from parents. There is no obligation to contribute and the children will not be treated differently according to whether or not any contribution has been made.
Charges are calculated to cover the total costs, which we keep to the bare minimum and indeed often subsidise. The school may cancel any trip / activity if insufficient parents are willing to support it through voluntary payment.
A residential adventure week is organised for Year 5 pupils. This is a voluntary activity where payment is required, as the majority of the visit is out of school hours.
