Using a randomized trial, this paper examines the impact of Preparing for Life, a pregnancy to age five home visiting and parenting program, on outcomes in middle childhood. I find significant treatment effects on cognitive skills (0.55SD) and school achievement tests (0.30-0.54SD) at age nine. There is no impact on socio-emotional skills and there is little evidence of treatment heterogeneity by gender, birth order, or distribution of ability. The effects are mainly driven by improvements in early parental beliefs.}, issn = {0022-166X}, URL = {https://jhr.uwpress.org/content/early/2022/03/31/jhr.0321-11557R1}, eprint = {https://jhr.uwpress.org/content/early/2022/03/31/jhr.0321-11557R1.full.pdf}, journal = {Journal of Human Resources} }
