Good to check, so yes not all. But all the ones we've had.

Going against the grain here, but we've used sitters before. You get to speak to the person in question before hand, they are fully CRB checked, some (ones we've had anyway) are parents and/or teachers.
All in, better than some spotty 15 year old who wants a lift/taxi for the mile journey home...
