Children in early childhood education and care (ECEC) spend a considerable amount of time interacting with their peers. However, open questions remain on whether and how children influence their peers' language development. The present study examined effects of peers' German receptive vocabulary (n = 1,871) on individual children's (n = 431)…

Data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 1,307) were used to estimate the additive and multiplicative benefits of high-quality child care between birth to 54 months of age and high-quality elementary school education between first and fifth grade. Results indicated…

This study examines growth in language and math skills during the summer before kindergarten; considers variation by family income, race/ethnicity, and dual language learner status; and tests whether summer center-based care sustains preschool gains. Growth in skills slowed during summer for all children, but the patterns varied by domain and…

The National Institute for Early Education Research (NIEER) conducted a landscape evaluation of early childhood programs in Indiana (IN) between the spring of 2021 and the summer of 2022. The evaluation included assessments of infant, toddler, and preschooler children's developmental status in multiple domains at two time points to measure growth.…

Data from the NICHD [National Institute of Child Health and Human Development] Study of Early Child Care and Youth Development (n = 1,307) were used to estimate the additive and multiplicative benefits of high quality child care between birth to 54 months of age and high quality elementary school education between first and fifth grade. Results…

We examined independent and interactive links among three central characteristics of children's experiences in early childhood education and care and the German receptive vocabulary of single language learners and dual language learners (DLLs). We allowed for possible differential effects depending on children's language background. Our sample…

Relations between early child care and adolescent functioning at the end of high school (EOHS; M age = 18.3 years) were examined in a prospective longitudinal study of 1,214 children. Controlling for extensive measures of family background, early child care was associated with academic standing and behavioral adjustment at the EOHS. More…

Using nationally representative data from the Longitudinal Study of Australian Children (LSAC; N = 5,107), this study assessed prospective connections between children's early education and care (EEC) experiences from infancy through preschool and their cognitive and behavioral functioning in 1st grade. Incorporating 6 waves of data, analyses…

The Massachusetts Preschool Expansion Grant (PEG) model supported and expanded high-quality preschool in high-needs communities. PEG required shared governance between local school districts and Massachusetts Department of Early Education and Care-licensed community-based programs. The 48 PEG classrooms provided free prekindergarten for…

The associations between trajectories of child care quality from ages 2 to 4 years and children's cognitive performance at 4 years ("n" = 250) were tested. Distinct quality trajectories were identified: low and high ascending Teaching and Interactions trajectory; low and high Provision for Learning trajectory. Membership in the high…

The purpose of this study was to extend existing research relative to the predictors of early mathematics skills. Using Vygotskian theory as a framework, our primary goal was to determine whether social skills or letter awareness skills served as better mediators between receptive language and early mathematics concepts. The secondary goal was to…

Children from immigrant families make up a growing proportion of young children in the United States. This study highlights the heterogeneity in early academic skills related to parental region of origin. It also considers the contributions of early home and nonparental care settings to the diversity in early academic performance. Using nationally…

Child care quality is usually measured along two dimensions--structural and process. In this paper the authors focus on process quality--the quality of child care center instructional practices and teacher interactions with students. They use an instrumental variables technique to estimate the effect of child care center process quality on…

Head Start programs currently provide early childhood education and family support services to more than 900,000 low-income children and their families across the United States with an annual budget of around $8 billion in state and federal funds. Researchers and policy makers have debated the program's effectiveness since its inception in 1964.…

Longitudinal data are used to examine whether effects of early child care are amplified and/or attenuated by later parenting. Analyses tested these interactions using parenting as both a categorical and continuous variable to balance power and flexibility in testing moderation. The most consistent finding was that maternal sensitivity during…
