Researchers and clinicians develop prevention programs for problem gambling. These programs, which mainly target youths, are usually applied within the school environment by teachers. It would be useful to verify beforehand whether teachers understand this problem and to evaluate their interest in applying these programs. We surveyed 517 teachers in order to assess their knowledge and attitudes with regards to gambling habits among youths. The results show that teachers have a good understanding of youth gambling problems. However, they are not ready to spend time on the prevention of gambling, even though they show interest in learning more. Recommendations to increase teachers awareness toward youth gambling are discussed as well as their general attitude and knowledge toward gambling.
