All licenced coaches should have a valid background check (DBS) in place.
To get your DBS check in place, you need to complete an ID form and have this verified by a recognised club official (your club chair, secretary or treasurer), or the county CCO. This ID form should be scanned and emailed to email@example.com, Archery GB will then guide you through the rest of the process. After your DBS certificate is issued, you can join the update service which will make your future renewals much easier and quicker.
You can read more about DBS checks on the Archery GB website: Vetting & DBS Checks
