The purpose of this study was to understand teachers’ awareness of and attitudes towards adolescent gambling in the United Kingdom. The researchers recruited 157 primary and secondary school teachers from UK mainstream schools to complete an online survey. Few teachers could correctly estimate the prevalence of gambling and problem gambling among youths (ages 11 to 14 and 15 to 18). Teachers thought that adolescent gambling was less serious than all other high-risk behaviours, except for drinking and driving. Teachers had fewer conversations with students about gambling than about other issues, except for drinking and driving. Teachers were also less confident in their ability to address gambling issues than alcohol and drug problems.
