This study drew data from a randomized trial of a statewide prekindergarten program in Tennessee and presents new evidence on the impacts of pre-k on 3rd-grade achievement using administrative data on children’s neighborhood environments. Results indicate that pre-k had no measurable impact on children’s 3rd-grade math achievement regardless of children’s neighborhood conditions. However, pre-k significantly improved 3rd-grade reading achievement for children living in high-poverty neighborhoods. The treatment effects on reading achievement were substantial: among children living in high-poverty neighborhoods, those who took up an experimental assignment to attend pre-k scored over half a standard deviation higher on average than the control group in 3rd-grade. In contrast, pre-k enrollment had, if anything, a negative effect on 3rd-grade reading achievement among children living in low-poverty neighborhoods. These differential effects were partially explained by alternative childcare options and contextual risk factors.
