This Welsh translation of the Demos pilot intervention in secondary schools across England and Wales with pupils aged 14-15 aimed to teach and minimise the risks associated with gambling and signpost where to go for help and support. These lessons designed by Demos, the PSHE Association, The Mentor Foundation UK (Mentor UK), the CNWL Problem Gambling Clinic and a range of independent teachers/advisers were designed to build up the resilience of teenagers to the risks related to gambling.
