I comment on the DBS (CRB) only and from the UK. I don’t know the process that is involved in other parts of the world.

The UK Criminal Records Bureau (CRB) and the Independent Safeguarding Authority (ISA) have merged into the Disclosure and Barring Service (DBS). CRB checks are now called DBS. However, you can’t do a criminal records check on yourself, nor on someone else.

When the DBS is run you provide certain documentation usually to an employer, to work within a ‘vulnerable client group’ this is then verified by person who is authorised, a little like signing a passport.

But If you need to run a check on yourself, you can get a ‘basic disclosure’ with details of any unspent convictions from disclosure in Scotland. http://www.disclosurescotland.co.uk/apply-online/

However, there are many ‘on line’ security services that can run basic checks, like known sex offences or violence charges but this is at a cost though.
