Later Impacts of Early Childhood Interventions: A Systematic Review

While much has been written on early childhood development and the near-term benefits to children selected to participate in interventions, few studies look at the sustained impacts of these programs. This systematic review aims to contribute to the field's progress by collecting those studies that offer high-quality, causal estimates, providing analysis on interventions shown to have sustained effects across a range of outcomes, and identifying research gaps to help guide future studies.
