Volleyball England affiliated clubs are bound by the Volleyball England Child Protection Policy. There are some great resources on the VE website site at http://www.volleyballengland.org/about_us/safeguarding with copies of the policy and good practice. Additionally the DBS / CRB process is explained.
Volleyball England insists upon the completion of enhanced disclosures. All volunteers working with young people on a regular basis MUST hold a valid VE CRB certificate.
SportsCoachUK run a number of good workshops but VE particularly recommend Safeguarding and Protecting Children (http://www.sportscoachuk.org/workshops/workshop-search) which is a very informative and worthwhile course to attend. This course is mandatory for Coach and Volley 1-2-3 accreditation.
