Pre-kindergarten (Pre-K) programs typically improve early academic skills, but those gains too often disappear after children transition to elementary school. At least three hypotheses explain this "fade-out" of Pre-K effects: Pre-K does not focus on the "trifecta skills" that uniquely support subsequent learning and…

Grouping children of different ages in the same preschool classroom (i.e., mixed age) is widespread, but the evidence supporting this practice is mixed. A factor that may play a role in the relation between classroom age composition and child outcomes is peer skill. This study used a sample of 6,338 preschoolers (ages 3-5) to examine the influence…

Children's early environmental experiences are often considered highly influential for later life development. Yet, environmental contexts, such as the home and early care and education (ECE) setting, and multiple aspects of each setting, are not typically examined concurrently. In this study, we examined associations between cognitive stimulation…

Policy observers have expressed concern over whether misalignment between pre-K and K--12 has negative consequences for children. This study considers students' exposure to redundant content across the pre-K and kindergarten years. Specifically, it asks, to what extent are skills and concepts taught in kindergarten redundant with skills and…

Although quality center-based child care is helpful in promoting school readiness for dual language learners (DLLs), little is known about the nonparental child care that young DLL children experience. DLL status is often confounded with immigrant status, ethnicity, and poverty. Using nationally representative data from the Early Childhood…

In 2011-2012, the Georgia legislature funded a series of ongoing studies to evaluate Georgia's Pre-K Program. The 2016-2017 Georgia's Pre-K Program Evaluation focuses on the results of the fourth year of this longitudinal study, through second grade. The purpose of the current evaluation study was to examine longitudinal outcomes for children…

Although high-quality early care and education (ECE) is widely accepted as one of the most effective means for promoting early learning and development, many ECE programs have limited impact perhaps because of issues with how ECE quality is defined and measured. This study seeks to expand definitions of ECE quality by asking which preschool ECE…

Although publicly-funded prekindergarten (pre-k) programs have been designed to promote children's school readiness, programs have tended to support early literacy skills to a greater degree than early language skills. Given the importance of both language and literacy skills for children's reading acquisition and academic achievement, the present…

Pennsylvania Pre-K Counts (PA PKC) is a state-funded prekindergarten program for 3- and 4-year-old children to help them gain school readiness skills. The goal of PA PKC is to help reduce educational disparities by providing high quality prekindergarten for children who lack opportunities or reside in environments that place them at risk of school…

This study is a secondary data analysis of data collected on preschool and kindergarten-aged children in Tulsa, Oklahoma in the fall of 2006 to study the effects of school and community-based public early learning programs on children's cognitive and social-emotional outcomes. Children in the study participated in the state-funded pre-k program,…

As policymakers contemplate expanding preschool opportunities for low-income children, one possibility is to fund 2, rather than 1 year of Head Start for children at ages 3 and 4. Another option is to offer 1 year of Head Start followed by 1 year of pre-K. We ask which of these options is more effective. We use data from the Oklahoma pre-K study…

A growing body of research has shown that high quality early care and education (ECE) is positively related to the development of children's social and academic skills (e.g., Barnett, 2011; Lamb & Ahnert, 2006; NICHD ECCRN, 2006). There is evidence that high quality ECE experiences can improve children's levels of social adjustment (Bierman et…
