Child protection charities are warning the government not to go too far in scaling back the vetting of adults working with children. Here is a simple change which would make the system less cumbersome and less expensive.
At the moment I have three CRB "clearances," one because I recently did some teaching at a local school, one because I am a licensed Reader in the C of E and occasionally take services and preach sermons at church, and one because I am a member of a Scout Fellowship, where my duties so far have extended to being in charge of the chocolate fountain at the Beavers' Fund Day, and guarding the lemonade and biscuits during a St George's Day service.
Each "clearance" costs the organisation £64, and must be a nice little earner for someone. To allow a clearance gained for one situation to apply to another would cut down the cost and bureaucracy without, as far as I can see, much adding to the danger to children.
