This paper provides novel insights into the science of scaling by examining an educational mentoring program in Mexico. The empirical analysis encompasses two independent field experiments and seizes a unique opportunity to learn from the government’s implementation of the same intervention. While the program originally implemented at scale demonstrates limited effectiveness, the introduction of a new modality with enhanced mentor training significantly improves children’s outcomes. Mentor-parent interactions are found to stimulate parental engagement at the community-school level. Our findings support the hypothesis that parents can play an important role in facilitating the scalability of educational programs.
