The guide first explains the elements of public policy, including laws, regulations, and the policies and practices of public institutions. Tips are provided on effective ways to impact each of these elements, so that a clear, consistent message can be delivered throughout the community regarding the dangers of underage drinking. Because changing laws and regulations is often viewed by many people as a difficult and daunting task, the guide provides the tools communities can use to deal with the legislative process at either the Federal, State, or local level. To help coalitions and organizations get started in their efforts to change public policy, the guide provides examples of opportunities that can launch a public policy initiative. The appendixes provide a variety of useful tools that can help communities first determine what kind of public policy initiative is needed. A checklist on underage-drinking laws and regulations can show an organization where improvement is needed. An elected official inventory form acquaints every coalition member with who represents them in Congress, the State government, and at the local level. Samples of letters and a telephone script are provided to assist groups in launching their public policy program; and a State-by-State legislative status report will indicate how their State compares with the other 49 States and the District of Columbia.
