Hi I just wondered if you could help me,
I was cautioned when I was 12 or 13 for assault, I am now 18 and haven't been in any trouble since, will this show up on a CRB check?
The answer to this depends on precisely what form of 'Assault' you were cautioned for. There are certain assault offences that will never be filtered from a DBS certificate. You can see for yourself a complete listing of these offences from the DBS link posted above. For example, if you were cautioned for an assault with intention to resist arrest or assault occasioning actual bodily harm, it will always show on a DBS certificate.
But If you were cautioned for (example) a common assault (Criminal Justice Act 1988 s39) and you were under 18 at the time of the offence, then under the 'filtering rules' introduced in 2013, such a caution will be removed after 2 years have elapsed.
You need to identify precisely what offence of assault you were cautioned for to answer your question.
