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,…

With the national push to expand preschool education, there has been growing interest in understanding why Latino families are enrolled in preschool at lower rates than non-Latino families. This study applied the accommodations model by Meyers and Jordan (2006) to the Early Childhood Longitudinal Study-Birth Cohort (n = 5,850) to provide a more…

This study employs data from both kindergarten cohorts of the Early Childhood Longitudinal Study (n ~ 12,450 in 1998; n ~ 11,000 in 2010) to assess whether associations between preschool participation and children's academic and behavioral outcomes--both at school entry (Mean age = 5.6 years in both cohorts) and through third grade--have changed…

The transition into kindergarten often serves as the basis for long-term disparities in educational attainment because initially small differences in early learning widen throughout the K-12 educational system. Given the long-standing disparities in their academic achievement related to being of low socioeconomic status and a racial/ethnic…

Using data from the Early Childhood Longitudinal Study Kindergarten Cohort of 1998 (n = 15,070), this study used propensity scores to examine the short- and long-term academic and psychosocial benefits of preschool education for a diverse sample of middle-class children. Compared with children who attended informal care at age 4, preschool…

Recent research has shown that the age composition of preschool classrooms influences children's early learning. Building on prior research, this study examines whether the association between classroom age composition and children's learning and development vary based on classroom quality and teacher characteristics using a subset of the Family…

The standard scoring of the CLASS PreK produces three domain scores that are widely used in research, practice and policy. Despite these domains being based on developmental theory and research, limited empirical evidence exists for the three-domain structure as operationalized in the CLASS PreK. Using the 2009 and 2014 Head Start Family and Child…

Because math knowledge begins to develop at a young age to varying degrees, it is important to identify foundational cognitive and academic skills that might contribute to its development. The current study focused on two important, but often overlooked skills that recent evidence suggests are important contributors to early math development:…

Academic preparedness, executive function abilities, and positive relationships with teachers have each been shown to be uniquely important for school readiness and success in the early elementary grades. Few studies, however, have examined the joint influence of these readiness variables on early school outcomes. Using data from a prospective…
