This study used a large administrative data set of Head Start programs across the United States, the Head Start Program Information Report (PIR), to explore disparities in program rates of screening, referral, and identification for early intervention between Migrant and Seasonal Head Start (MSHS) and Head Start (HS) programs. Results from…

This dissertation aims to elucidate the complexities of chronic absenteeism in Head Start Programs post-COVID-19 to enhance early childhood education practices and policies. Utilizing a mixed-methods approach, the study investigates the causes of absenteeism by surveying and interviewing 50 participants from a Head Start Program in the New York…

Income-based childcare programs provide children access to developmentally appropriate and vocabulary-rich literacy experiences. For this study, participating U.S. Head Start Centers requested families complete a weekly home literacy log to encourage vocabulary-rich shared book reading activities in the home. Using participant characteristics,…

With the increasing frequency and intensity of extreme weather disasters, it is essential for Office of Head Start staff and Early Head Start/Head Start (EHS/HS) program leaders to prepare for and respond effectively to these challenges. This brief presents data on the number and percentage of EHS/HS sites located in extreme weather affected areas…

The year 2025 marks the 25th anniversary of implementation of New Jersey's court-ordered, full-day, high-quality preschool program in the state's 31 high-poverty, urban, "Abbott" districts. As the state continues to expand the program beyond these districts, it is imperative to examine whether Abbott Preschool is effectively meeting the…

Ongoing expansion of early education services in the United States is often rooted in these programs' contribution to development that promotes later academic and behavioral competence. Multi-tiered systems of support (MTSS, sometimes referred to as Response to Intervention) represent one increasingly common resource to promote desired outcomes…

The goals of the current study were: 1) to modify and expand an existing spatial mathematical language coding system to include quantitative mathematical language terms and 2) to examine the extent to which preschool-aged children used spatial and quantitative mathematical language during a block play intervention. Participants included 24…

The present study examined how the dosage and quality of the federal preschool program "Head Start" (HS) in the US related to children's self-regulation skills in kindergarten. Using Propensity Score Matching and multiple regression (OLS), this study explored how the number of years and hours a week of HS were related to self-regulation…

California recently committed to making prekindergarten (PreK) universal through the expansion of transitional kindergarten (TK) and other state-funded programs. Between 2021-22 and 2023-24, TK enrollment doubled, from about 75,000 to over 151,000 children. Approximately 59% of eligible 4-year-olds enrolled in TK in 2023-24. Across publicly funded…

This article describes a conceptual and empirical approach for estimating a human capital production function of child development that incorporates mother- or child-fixed effects. The use of mother- or child-fixed effects is common in this applied economics literature, but its application is often inconsistent with human capital theory. We…

Background: Public preschool can provide opportunities for earlier detection of child health problems and receipt of special needs services. This is especially important for children from low-income households who disproportionately face cost barriers to obtaining health screenings and services. Objective: This study explores the possibility that…

The "Child Behavior Checklist for Ages 1.5-5" (CBCL/1½-5) has been widely used by researchers and clinicians in the field of special education and psychology. The purpose of this study was to examine the psychometric properties of the CBCL/1½-5 with a sample of preschool children from low-income families using the Rasch model.…

To provide a landscape of mathematics activities children experience in U.S. preschool and kindergarten classrooms, we observed time children spent in mathematics activities (and -- as a contrast -- literacy) in 101 geographically diverse early childhood classrooms in seven U.S. states. We also observed what mathematics content, grouping…

Children from backgrounds of poverty often lag behind more advantaged peers in early language skills, including breadth and depth of vocabulary knowledge. We report the results of a pilot study of an explicit and elaborated vocabulary intervention in preschool classrooms serving children from lower-income backgrounds. The intervention used…

Identifying factors related to expulsion risk is of great need due to the high and disparate rates of young children routinely excluded from preschool classrooms. This study aimed to explore the pathways to expulsion risk among a sample of 88 preschool children from 22 Head Start classrooms. Data were collected on children's inhibitory control…
