Background: When New York City's (NYC) Division of Early Childhood Education (DECE) enacted their historic expansion of free programming for four-year-olds under Pre-K for All, they designed a complex system of professional learning (PL) to support teachers and high-quality programming. This study, developed in partnership between NYU and DECE,…

Background: Early care and education (ECE) has lasting, positive effects on children's school readiness (Phillips et al., 2018; Yoshikawa et al., 2013). Over the past several decades, access to city or state-funded prekindergarten (pre-K) has increased considerably (Friedman-Krauss et al., 2023) with well-documented, positive impacts on child…

Background: Pre-k convergence refers to the tendency for the positive effects of pre-k on children's academic skills to diminish over time, observed across decades of observational and experimental studies (Ansari et al., 2020). Researchers have tested multiple mechanisms to explain convergence, with mixed results; none of the proposed mechanisms…

Background: Early care and education (ECE) quality has been a topic of discussion for several decades (Burchinal, 2018; Mashburn et al., 2008; NICHD ECCRN, 2002). The structure-process-child outcomes theory proposes that structural features (e.g., teacher education, class size) of quality predict process quality (e.g., teacher-child interactions),…

Background/Context: School readiness refers to the foundational skills and behaviors children leverage as they begin kindergarten, including a combination of early academics, executive function (EF), and social-emotional competencies. In both high-income and low- and middle-income countries, these early skills collectively enable children to…

Background: Decades of research suggest that when young children are enrolled in high-quality pre-K classrooms they have better literacy, language, math, and social outcomes at the end of the pre-K year. A traditional approach to capturing the quality of children's experiences, including the quality of their engagement with academic content and…

Enrollment in eighth-grade algebra doubled from the 1990s to 2012 (National Center for Education Statistics, 2013) as research demonstrated that Algebra I operates as a "gateway" to advanced mathematics courses in high school (Adelman, 2006), and that students who succeed in Algebra I in middle school have more success in mathematics…

The academic achievement gap between children from the lowest- and highest-income families appears to have risen in recent decades in the United States. Such income-related disparities in academic skills are already present when children enter elementary school, suggesting that the explanation for changing gaps can be traced to changing…

This panel examines research on early education from two research practice partnerships, the Baltimore Education Research Consortium (BERC) with Baltimore City Schools and Johns Hopkins University in Baltimore, Maryland, and the Stanford-SFUSD Partnership with San Francisco Unified School District (SFUSD) and Stanford University in San Francisco,…

A consistent finding across early childhood interventions targeting mathematics and other achievement-related skills that is that initial treatment effects fade over time, with children not receiving the intervention catching up to children who did (Clements et al., 2013; Leak et al., 2010; Puma et al., 2010). One popular explanation for this is…

Relatively few rigorous studies of the effectiveness of contemporary public prekindergarten programs have been conducted despite the growing number of programs and large monetary investments that accompany them. The study on which this presentation is based was launched in partnership with the Tennessee State Department of Education's Division of…

Prior research suggests that Spanish-speaking Dual Language Learners (DLLs)--young children who must master two languages simultaneously, their home language and English (Espinosa, 2013)--differentially benefit from quality Early Childhood Education (ECE), and in particular from Head Start, compared with children of other subgroups and…

School readiness is best conceptualized as a multidimensional construct that spans several skill domains. Academic and behavioral skills have been identified as important components of school readiness that uniquely predict learning and achievement. Few studies, however, have examined the effects of these skills simultaneously or explored how they…

To date, no studies have documented how much early childhood experiences have changed over time. In the current study, researchers use two large, nationally representative datasets of kindergarten entrants to document the following: (1) How have children's early childhood experiences changed between 1998 and 2010?; (2) To what extent have…

This presentation reports on the goals and preliminary outcomes of the Child-Parent Centers (CPC) Expansion Project, which is a PreK to 3rd grade school reform model aimed at improving the short- and long-term outcomes of participating children and families. The model provides continuous education and family support services to schools serving a…
