"Research Findings:" Despite the prevalence of integrating early childhood education (ECE) into formal schooling, there is limited evidence on how school-based ECE affects children compared to other types of ECE, particularly in Low and Middle-Income Countries (LMICs). Therefore, this study examined school-based ECE programs compared…

Research Findings: There are sparse data on children's use of executive function (EF) and spatial skills in block play. However, there are important implications for studying EF and spatial skills with blocks across cultures, especially regarding best practices for supporting social-cognitive development in under-resourced populations and…

This study investigated associations of three teacher-reported health indicators--hunger, tiredness, and sickness--with kindergarten readiness skills in San Francisco Unified School District (N = 12,423; female = 48%; M[subscript age] = 5.47, SD[subscript age] = 0.30, range[subscript age] = 4.67--7.00; Asian American = 26%, Black = 5%, Latinx =…

Research Findings: We assessed socio-emotional behavior, nonverbal reasoning, German receptive language, and motor skills of refugee children attending early childhood development [ECD] programs and of those who did not (N = 207, mean age = 69.4 months). Young refugee children overall demonstrated lower levels of development and more…

Research Findings: The present study explored the extent to which teachers' participation in professional development focused on children's social-emotional learning moderated the relation between self-reported burnout and teacher-child interactions. The sample included 307 Head Start preschool teachers who participated in a large randomized…

Research Findings: Using a sample of 568 students from 61 kindergarten classrooms whose primary caregivers completed a questionnaire describing their child's early childhood education and care (ECEC) by year from birth to pre-kindergarten, we identified seven pathways characterizing children's ECEC experiences using a latent class analysis. Once…

Pretend play may be beneficial for young children's social development. However, empirical results to date are inconsistent and limited, which is partly due to a lack of psychometrically sound measures for children's social pretend play competence. The current study aimed to compare and validate different assessment methods for children's social…

Rejection by peers has devastating effects on children's social-cognitive development. As language difficulties have been found to be one of the underlying causes of peer rejection, the present study focused on the relation between these two variables. Specifically, this study was the first to test a hypothesized model connecting children's level…

Research Findings: Kindergarten Entry Assessments (KEAs) -- assessment tools used at the beginning of kindergarten to provide educators with a snapshot of children's readiness for school -- are increasingly being adopted by states across the country. The purpose of this study is to examine the implementation of North Carolina's KEA through…

Early fine motor ability is significantly associated with later achievement, even after controlling for typical child-level predictors of school outcomes. Previous longitudinal studies have confirmed this but typically have not included low-income, at-risk populations. Research has distinguished two different aspects of fine motor skills: those…

Research Findings: Public policy has increasingly focused on expansion of preschool access for underserved students and systematic evaluation of preschool quality and students' readiness for school. However, such evaluation is limited by a lack of thoroughly validated assessments for use with preschool populations. The present study examined the…

Research Findings: Although there has been considerable research on the associations between the qualifications of teachers in center-based settings and preschool-age children's developmental outcomes, very little is known about the relationships between home provider qualifications and the developmental outcomes of toddlers who attend licensed…

Research Findings: Pretend play is an important context that supports young children's developing social-cognitive and creative abilities. The play behaviors of 70 sibling dyads in early and middle childhood were examined for the following indices of creativity in play: (a) play themes (set-up/organization, expected, creative), (b) object use…

Research Findings: As policymakers expand access to preschool, the sociodemographic composition of preschool classrooms will become increasingly important. These efforts may create programs that increase the concentration of children from low-income families or, alternatively, foster the creation of socioeconomically diverse preschool classrooms.…

This article aims to contribute to the ongoing evaluation of the Australian Early Development Index (AEDI) by investigating its construct and concurrent validity with a subsample of 642 children aged 4 to 5 years drawn from the Longitudinal Study of Australian Children (LSAC). Construct validity was examined by considering the theoretical…
