What a chaperone is
Under the Children and Young Persons Act 1933, the Children and Young Persons Act 1963 and the Children (Performances and Activities) (England) Regulations 2014, all children who take part in licensed performances must be supervised by a responsible adult.
If they are not supervised by a parent or guardian they must be supervised by an approved Chaperone who is responsible for looking after children during the course of a performance, including travel to and from the event. A chaperone is expected to exercise the same care and control as a good parent would, with a view to securing the child's health, comfort, kind treatment and moral view. The Chaperone must have a valid licence issued by the Local Authority.
