On 1 December 2012 the Criminal Records Bureau (CRB) and the Independent Safeguarding Authority (ISA) merged to form the Disclosure and Barring Service (DBS).
As a result ‘CRB checks’ are now called ‘DBS checks’.
Volunteering England has produced a user-friendly guide to the new DBS/CRB checking system which you might find useful. This guidance is principally aimed at volunteers and volunteer involving organisations and relates to the disclosure and barring system as it currently exists.
The guide contains simple flow charts to help determine if the work is Regulated or not and if a DBS check is needed. You can download these below:
