Scaling Success: Challenges and Insights

This chapter explores the complexities of scaling effective interventions from controlled settings to the real world, examining why successful programs often falter when expanded. It highlights critical factors such as the alignment of target populations, the phenomenon of 'voltage drop,' and the importance of research replication for policy implementation. Through case studies and discussions on program fidelity, the chapter underscores the need for rigorous evidence and frameworks to maintain the integrity of effective interventions as they grow.
