In the United States, the long-term effects of early childhood programs have been given particular weight in research on early childhood education and in policy debates about the value of prekindergarten. Many research teams were building the evidence base on U.S. early childhood programs to inform that discussion when studies were upended by the…

Pre-kindergarten (Pre-K) improves the school readiness of all children, but less is known about whether associations between enrollment in Pre-K and different indicators of social-emotional and executive functioning (EF) skills are sustained as children move into and across elementary school. The current study examines associations between…

Though there is an expanding field of research on public prekindergarten, there is a relatively little comprehensive investigation into what public prekindergarten costs. We address some of the absences in the literature by analyzing public-sector expenditures for the city of Boston's public prekindergarten program, a particularly high-quality…

Preschool improves children's kindergarten readiness, but the cognitive outcomes of preschool enrollees and nonenrollees tend to converge partially or fully in elementary school. In older programs, most of this convergence occurs in kindergarten (Li et al., 2016), but evidence from today's programs is sparse. Using data on 4,971 children who…

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…

This study leverages naturally occurring lotteries for oversubscribed Boston Public Schools prekindergarten program sites between 2007 and 2011, for 3,182 children (M = 4.5 years old) to estimate the impacts of winning a first choice lottery and enrolling in Boston prekindergarten versus losing a first choice lottery and not enrolling on…

While there is a consensus that attending preschool better prepares children for kindergarten, evidence on the factors that sustain the preschool boost into the early elementary years is still emerging. To add to this literature, we use lottery data from applicants to oversubscribed schools in Boston Public Schools (BPS) prekindergarten program to…

In recent years, policymakers' and practitioners' interest in school climate as a contributor to K-12 student learning and classroom processes has increased, both in the US and internationally. However, researchers have not yet examined the influence of school climate on the youngest learners in these contexts -- prekindergartners. Using data from…

Classroom organization is an important facet of prekindergarten quality but is typically measured at a "global level" and as a "single construct." Little is known about how experiences of different facets of classroom organization--namely, exposure to teacher organizational strategies--vary across "individual…

General measures of process quality are widely used in the early childhood education (ECE) field. However, the evidence regarding associations between the most widely used process quality measure, the Classroom Assessment Scoring System (CLASS; Pianta et al., 2008), and children's school readiness gains during the preschool year is mixed. Using…

Parental engagement in home-based learning activities is linked to children's academic skills. Yet, interventions that try to enhance parental engagement--sometimes targeted to families with low levels of education--have small effects. This study aimed to inform supports for families by examining how different types of home-based learning…

The increasing diversity of young children enrolled in state pre-K and Head Start programs has prompted examination of varying impacts for identified subgroups of young children. We argue that questions of subgroup impacts and the processes that may account for them should be prioritized in future evaluations of these programs. Three subgroups at…
