A robust body of evidence over the past half a century has documented the importance of early childhood experiences for adult outcomes. From maternal prenatal care to early intervention in infancy and toddlerhood, and through high-quality care and educational experiences in the preschool years, support services and programs for families and young…

Public support for and government investments in early childhood education (ECE) are at an all-time high. Research has identified early childhood as a critical period for brain development, work that has spurred interest in expanding ECE programs across the United States. But not all programs produce positive effects at the end of the preschool…

Many early care and education (ECE) institutions--including Head Start, state quality rating and improvement systems (QRIS), and school district pre-K programs--use classroom quality observations in their quality improvement or monitoring processes. As many states expand their ECE programs, they grapple with questions about how best to use data…

High-quality pre-K sets children on a path for success in kindergarten and beyond. Yet most children in the United States do not attend high-quality programs, with particularly pronounced gaps in quality for children from families with low incomes, dual language learners, Black children, and Latino children. Ensuring equitable access to…

An investment in early childhood education pays off when the benefits continue into adulthood. Although many recent preschool interventions have had positive, short-term effects on young children's language, literacy, mathematics, executive function, and social-emotional development, studies show that related gains in cognitive and academic skills…

Improving the quality of teaching and instruction takes time and planning and may be costly and require intensive work. This is particularly true when trying to make improvements among multiple preschool sites, because preschool systems often lack a cohesive infrastructure for supporting high-quality implementation of curricula and teacher…

In this paper we use data from students who participated in the oversubscribed Boston Public Schools (BPS) prekindergarten program as a window into variation in the program's medium-term effects. We first examine whether, for the sample of students who applied to oversubscribed BPS prekindergarten programs, there is variation in the effects of the…

Early childhood interventions can be highly cost effective when positive impacts are sustained into adulthood. Yet while many recent preschool interventions have been found to have short-term effects on young children's language, literacy, mathematics, executive function, and social-emotional development, studies show that impacts on cognitive and…

This report presents results from the Newark, New Jersey, site of the Foundations of Learning (FOL) Demonstration, an intervention and random assignment evaluation of a curriculum designed to target children's behavior and emotional adjustment through the training of preschool teachers. The demonstration adopted the model used by CSRP (formerly…
