Gambling employees, such as casino and lottery workers, are trained in responsible gambling (RG) to minimize gambling-related harms in their customers. One way to assess the effectiveness of employee RG training is the use of benchmarking. Benchmarking allows a company or individual to compare their practices with the industry’s best practices. There are no existing benchmark criteria for RG staff training, however. Thus, the current study assessed benchmark criteria for the training of gambling employees through feedback from RG experts. It also examined how often benchmarking should be done, and who should be responsible for it.
