This brief provides practical insights and advice for programmers, funders, researchers, and policymakers as they take social norms programming to scale. Drawing on our broad and diverse experiences globally as practitioners and activists, we also highlight key challenges embedded in social norms change work and ways to overcome them. Most importantly, CUSP suggests that effectively transforming harmful social norms at scale requires moving beyond the current thinking of scale as a numbers exercise to better reflect key principles from social norms change work. At this critical moment, CUSP encourages the international development community to 1) ensure that gendered, social justice principles and values are prioritized when programming at scale; and, 2) support innovation of new social norms change approaches that also reflect these principles. While embracing this approach, CUSP also posits that prioritizing the agency, well-being and safety of communities is essential to achieving impact and ensuring sustainability.
