All educational establishments have a legal obligation to safeguard and protect the children that study there. For this reason any primary teaching positiob will require an enhanced DBS check / CRB check.
An enhanced DBS check will contain a full report on any criminal convictions you have, it also includes a local police check in each of the boroughs you have lived in.
But what if I was arrested under caution but not charged?
Not to worry. A DBS check only shows convicted offenses. If you were not charged and convicted then this will not show on your DBS check.
