Purpose: The purpose of this study was twofold: (a) to describe how the language diversity (i.e., the within-group variability in dual-language skills) of Latino dual-language learner (DLL) preschoolers was related to their science readiness skills and (b) to describe the importance of language of science instruction for Spanish-dominant children.…

Executive function (EF) skills play a crucial role in young children's academic and social-emotional development. Given that factors associated with poverty can compromise the development of EF skills, it is vital to continue to examine what factors help predict and support EF skills in children from at-risk backgrounds. Using a sample of Head…

Research has found that children who attend Head Start for more than one year tend to score higher on cognitive skills at the end of pre-K or at kindergarten entry than children who attend for one year or less (Lee 2011; Wen et al. 2012b; Xue et al. 2016). Although attending Head Start for more years is linked with higher cognitive scores,…

Research Findings: A constellation of social positions of difference can contribute to substantial variation among children from culturally and linguistically diverse (CLD) backgrounds. Using data from the "Head Start Family and Child Experiences Survey" 2009 cohort, the present study identified intersectional typologies of cultural…

Using a nationally representative sample of 3- and 4-year-old Spanish-speaking dual language learners (DLLs) attending Head Start (N = 654), this study examined whether mean levels of and variability in peers' English receptive vocabulary skills were associated with DLLs' English and Spanish receptive vocabulary skills in the spring. In addition,…

A sample of 496 early childhood teachers was assigned randomly in two phases to a series of professional development (PD) interventions. Phase I intervention was a 14-week course on effective teacher-child interactions. Participants were then re-randomized into Phase II intervention, which consisted of individual, interactions-focused coaching.…

The purpose of this study was to conduct a pilot randomized controlled trial to evaluate the efficacy of an intervention for enhancing the language development of young children enrolled in home visiting programs. The participants were 59 children (18-30 months old) enrolled in one of three types of home visiting programs. Children's language…

The sharing of American Indian and Alaska Native (AIAN) cultures and lifeways provides opportunities for helping young children form deep connections to their community, which, in turn, aids in the development of their early language and literacy skills. This issue brief--based on interviews with eight Tribal Maternal, Infant, Early Childhood Home…

This study explores the effects of the two-generation program Career"Advance"--which combines education and training for parents in healthcare with Head Start for children--on children's academic, language, mathematics, and inhibitory control followed for 3 years. The sample (collected in Tulsa, Oklahoma from 2011 to 2018) includes 147…

Using data from the Head Start Family and Child Experiences Survey 2009 Cohort, this study investigated the school readiness trajectories of 2,908 Head Start children from Head Start to kindergarten. Multilevel growth curve models examined differences by immigrant-origin status and the moderating role of enriching experiences. Research Findings:…

A systematic review of the literature (1965-2022) and meta-analysis were undertaken to compare the school readiness skills of children participating in public pre-kindergarten (pre-K) or Head Start. Seven quasi-experimental studies met the inclusion criteria for the meta-analysis and 38 effect sizes were analyzed. Results indicated no reliable…

Public preschool boosts academic skills in kindergarten, but little is known about whether that boost lasts to third grade because many studies stop directly assessing children after kindergarten. The current study tests for sustained associations between preschool attendance and an array of repeatedly measured, directly assessed language and math…

This study examined the literacy trajectories of 185 Head Start-eligible Black children from preschool to first grade enrolled in a high-quality early learning program physically connected to an elementary school where they attended kindergarten and first grade. Social emotional, language, and literacy skills were assessed in the fall and spring…

The purpose of this qualitative study was to examine parent involvement practices of the Early Beginnings Head Start program and to determine the impact that parent involvement has on the early language and literacy development of preschool children. Although parent involvement practices are evident throughout Head Start programs, the specific…

Developing self-regulation at an early age is important for children's success in school and in life. Self-regulation involves the ability to remember instructions, shift attention from one thing to another, and reduce the intensity and frequency of impulsive emotions and behaviors. "Red Light, Purple Light" is a preschool program that…
