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…

Decades of research on early care and education have shown that four-year-old children who enroll in prekindergarten (pre-K) programs start kindergarten scoring higher on assessments of academic skills than those who do not. A handful of long-term follow-up studies of pre-K have also found that these programs can have lasting beneficial impacts on…

The Boston Public Schools (BPS) district is the first large school system in the United States to design and implement a curriculum and professional model--called "Focus on Early Learning"--to align instruction across its well-known, high-quality public school pre-K program and early elementary school grades. Schools opt in and can…

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…

Early math ability is one of the best predictors of children's math and reading skills into late elementary school. Children with stronger math proficiency in elementary school, in turn, are more likely to graduate from high school and attend college. However, early math skills have not historically been a major focus of instruction in preschool…

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…

In the context of a persistent achievement lag among low-income children despite substantial investments in early education, policymakers and practitioners continue to seek ways to improve the quality of children's preschool experiences. The Making Pre-K Count study addresses whether strengthening prekindergarten (pre-K) instruction in math,…

Early math skills are a strong predictor of later achievement for young children, not only in math, but in other domains as well. Exhibiting strong math skills in elementary school is predictive of later high school completion and college attendance. To that end, the Making Pre-K Count and High 5s studies set out to rigorously assess whether…
