CRB is now known as DBS. This is what a the two levels of DBS check will show:
Standard Disclosures: discloses all convictions, cautions, final warnings and reprimands (that are not protected) held on the Police National Computer, regardless of whether they are spent or not
Enhanced Disclosures: also disclose all convictions, cautions, final warning and reprimands (that are not protected) held on the PNC. Enhanced disclosure may also reveal local police information (e.g. details of allegations, arrests, not guilty verdicts etc.) that is felt to be relevant to the job
There are a number of other employment vetting checks that you may be asked to undergo. Please see here for more information.
The following are not convictions, cautions, final warnings or reprimands and will not be disclosed on a Standard DBS check. As local records, they may be disclosed on an Enhanced DBS check at the discretion of the Chief Constable:
Harassment warnings: only becomes a criminal matter if breached
Anti Social Behaviour Orders (ASBOs): only becomes a criminal matter if breached
Community Resolution Orders
Cannabis warnings (usually issued on the street)
Fixed penalty notices (FPNs)
Penalty notices for disorder (PNDs)
The section would only show up if there was an arrest at the same time (as it is police information that shows up on a DBS check) & an enhanced disclosure is being conducted on the person in question.
