We study an intensive math instruction policy that assigned low-skilled 9th graders to an algebra course that doubled instructional time, altered peer composition and emphasized problem solving skills. A regression discontinuity design shows substantial positive impacts of double-dose algebra on...

I exploit the staggered roll-out of a universal early childhood development program in Chile to assess the impact of a comprehensive approach to early childhood development on outcomes in middle childhood. Using variation across time and municipalities, I study outcomes such as school...

We present findings from an integrated early childhood parenting program on stunting and wasting in Sierra Leone, West Africa. Importantly, where half the communities were randomly assigned to receive the parenting program and the remaining half served as a control that received standard...

High school vocational education has a controversial history in the United States, largely due to a perceived tradeoff between teaching readily deployable occupational skills versus shunting mostly disadvantaged students away from the educational and career flexibility afforded by general...

What are the long-term effects of universal preschool programs on child outcomes? We review 26 studies using natural experiments to estimate the effects of universal preschool programs for children aged 0-6 years on child outcomes measured from third grade to adulthood. Studies comparing...

We study the effects of grade retention on secondary school performance by considering a change in Colombia's educative legislation. In 2010, the rule that forced schools to retain up to a 5% of students was abolished. Exploiting variation in schools' retention rates in a...
