I have name changed for this as am identifiable from other threads and don't want to go down as a troublemaker!
Just curious as our school now needs all parent helpers to be crb checked. This was always the case for regular help in the classroom, but has now been extended to one-off accompanying school trips and even just walking with a group of children with the teacher and other parents, eg if they go off site for any reason. In this latter situation there is no chance of being one-on-one with any child, and it is happening weekly at the moment.
I personally feel this it a step too far especially as the school asks for parents to pay the cost of the crb (apparently the LA charges them to process the application). It means that not many people can/will volunteer for things and the same people have to step up all the time.
What does your school require, and do they ask parents to pay?
