This Toolkit is intended for those working in the beverage alcohol industry—producers, trade associations, and social aspects organizations (SAOs)—who are currently undertaking or planning to undertake programs to address alcohol-related harm. It provides an overview of what is involved in evaluating prevention programs, laying out the necessary steps and identifying different available options. Two case studies then apply the principles of evaluation to two scenarios that mirror the types of initiatives likely to be implemented by industry stakeholders: an awareness campaign around the use of designated drivers and a school-based alcohol education program.
