This article investigates the rollout of universal primary education (UPE) policies in Ethiopia, Malawi, and Uganda to assess their long-term causal effects on schooling attainment. Consequently, we employ a fuzzy regression discontinuity design (RDD) to assess the effect that increased schooling helps lower adolescent sexual activity, marriage, and births, as well as adult labor force activity among women. Our findings show that the UPE policies were effective in increasing educational attainment across all three countries between 0.6 and 1.5 years of completed schooling. Additionally, we show that increased schooling induced by UPE had lowered sexual activity, child birth, and marriage rates during adolescence. We find that the effects of schooling do not significantly improve labor force participation and employment.
