Campaigns to provide information about the returns to additional years of schooling have been lauded as low-cost ways to boost student engagement in school. We review 13 such programs in low- and middle-income countries across Africa, Asia, the Caribbean, and Latin America. On average, we find that information campaigns that provide information on the returns to education lead to more accurate student beliefs about the average value of further schooling, but also that those beliefs may be revised either upward or downward, depending on the direction of initial bias. We find positive and significant average impacts on school participation (with an average standardized effect size of 0.02) and on student learning (0.05), with significant variation across studies. Three of the studies with large samples show sizeable impacts on dropout rates specifically. Costs tend to be low, so providing information about the returns to additional years of schooling is likely cost-effective. We discuss variation across studies, design decisions, implementation challenges, heterogeneous effects, and ethical considerations.
