The new scheme is designed to be both simpler and more comprehensive than previous arrangements. It recognises the need for a single process to assess all individuals who wish to do certain work or volunteer with children and vulnerable adults. A new body, the Independent Safeguarding Authority has been set up to make decisions as to who should be barred from working with vulnerable groups. Instead of several different lists of barred individuals, the ISA maintains a single list of people barred from working with children and a single list relating to vulnerable adults. Anyone wanting to work or volunteer regularly with children or vulnerable adults will be required by law to become registered with the ISA, and employers will be legally required to check that new employees are registered. Everyone who applies to register will be vetted in a similar way to existing Criminal Records Bureau [CRB] arrangements. The ISA will only consider a case where there is relevant information which suggests that they might pose a risk of harm to vulnerable groups. The scheme becomes mandatory for new starters and movers from the 1st November 2010. Guidance can be found on the Idependent Safeguarding Authority website www.isa-gov.org.uk
