Cross-sector partnerships are essential in addressing and improving the vital conditions of a community. Navigating these partnerships requires a specific set of skills not often taught in traditional public health settings. Building on a series of previous efforts to support IVP practitioners in strengthening partnerships to advance community injury and violence prevention efforts, Safe States identified a set of “essential skills” necessary for establishing and sustaining these partnerships. This three-part self-paced training series covers the skills needed to be intentional in your preparation to partner, build and maintain trust with partners, and manage tension and conflict. While each module can be taken independently, the lessons in the series are intended to build on one another. Throughout each lesson, there are skill-building exercises included to help you apply what was covered in the session.
