As we define it, a Theory of Change describes the main building blocks required to bring about a given long-term goal. Our goal is a world in which children are no longer exploited. Our Theory of Change describes the types of interventions (e.g. a single program or a comprehensive community initiative) that are needed to bring about the changes depicted in the pathways. Each outcome in the pathway of change is tied to an intervention, revealing the often complex web of activities that is required to bring about change.
