Criminal Records Bureau (CRB) checks are now called Disclosure and Barring Service (DBS) checks. Anyone involved on a weekly basis teaching chess to children, helping out at a school or club, or transporting children to tournaments, needs to undertake a DBS check.
Such checks can be arranged online through the Government website, but an Enhanced Check there costs £44. Instead, an scheme has been set up between the Suffolk County Chess Association and Community Action Suffolk, whereby checks can be undertaken, also online, at a cost of only £15.
Anyone who teaches chess to children at a school or club, or coaches children at home, should apply for a DBS check. As the administrator of this scheme, contact me if you need to undergo a check.
