The purpose of this study was to explore the use of code-switching in the narratives of dual-language Latino preschoolers, specifically by examining its incidence, types, functions, and grammaticality. Previous work has investigated code-switching in younger children and in older children and adults, but relatively little work has investigated…

The analyses presented here are part of a larger project, "Understanding Children's Transitions from Head Start to Kindergarten" (HS2K), a joint research venture between NORC at the University of Chicago, Child Trends, and the National P-3 Center at University of Colorado Denver, with funding from the U.S. Administration for Children and…

The measurement of self-regulation in young children has been a topic of great interest as researchers and practitioners work to help ensure that children have the skills they need to succeed as they start school. The present study examined how a revised version of a commonly used measure of behavioral self-regulation, the…

ORS 327.016 directs the Oregon Department of Education (ODE) to prepare an annual report on English learner program funding and student outcomes. The report's intention is to describe the population of English Learners in Oregon and provide a summary of district and state progress towards meeting their needs and objectives. The ODE annually…

Using a nationally representative sample of dual language learners (DLLs) attending Head Start, this study investigated how the language used for instruction and the proportion of DLLs in the class was associated with English and Spanish receptive vocabulary development between the fall and spring (n = 531). Based on teacher report of the language…

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 Arkansas Better Chance (ABC) program longitudinal study (2009-2020) reviews the changing circumstances and outcomes of participation in Pre-K services in Arkansas. The "core comparison" of this study is between ABC participants and students who had no known Pre-K participation but have similar household income levels. The results…

Federal incentives and requirements under the Obama administration spurred states to adopt major reforms to their teacher evaluation systems. We examine the effects of these reforms on student achievement and attainment at a national scale by exploiting their staggered implementation across states. We find precisely estimated null effects, on…

The idea that language skills support school readiness, predicting later self-regulation and academic success, is widely accepted. Although vocabulary is often emphasized in the developmental literature, the ability to use language appropriately in the classroom, or "social communication skills," may also be critical. This paper examined…

Program administrators and policy makers have placed a priority on expanding access to inclusive, center-based early care and education (ECE) for low-income children with special needs, a "doubly vulnerable" population characterized by academic and social-emotional achievement gaps at kindergarten entry. Yet, no research has documented…

A recent report commissioned by the Office of the District of Columbia Auditor examined the accuracy of enrollment projections by the District of Columbia Public Schools (DCPS) and by charter local educational agencies (LEAs). While the report found that enrollment projections were fairly consistent with LEA level enrollment, based on a sum of…

This article reports on the study of differential change trajectories for early childhood approaches to learning. A large sample (N = 2,152) of Head Start children was followed through prekindergarten, kindergarten, and first grade. Classroom learning behaviors were assessed by teachers through the Preschool Learning Behaviors Scale twice in Head…

The 2020 Census risks undercounting thousands of young Colorado children, depriving communities of federal funding and political representation for the next decade. Children under age 5 are more likely to be missed by the census than any other age group, with children of color, non-English speakers, and kids living in high poverty communities at…
