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…

The current paper reports long-term impacts of the Chicago School Readiness Project (CSRP) on measures of achievement, cognitive functioning, and behavioral regulation taken toward the end of students' high school careers. The CSRP was a self-regulation-focused early childhood intervention implemented in Head Start centers serving high-poverty…

A growing number of early childhood interventions are intended to be used by classroom teachers to support children's emergent literacy development, yet we know little about for whom such interventions might be effective. In this study, we examined whether children's initial emergent literacy skills (alphabet knowledge, phonological awareness,…

This study evaluated the implementation and effectiveness of My Math Academy and My Reading Academy, two digital learning programs, in supporting early math and literacy skill development during the 2021-2022 school year in Tyler Independent School District, Texas. In a district where 85% of students were eligible for free and reduced-price meals,…

Background: The long-term effectiveness of Head Start remains a topic of debate. Previous research with families of children enrolling in Head Start at three years of age has shown patterns of familial risk moderate the short-term effects of Head Start suggesting some children benefit more than others. However, we know little about patterns of…

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 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…

Preschool classrooms provide a unique context for supporting the development of children with social-communication challenges. This study is an uncontrolled clinical trial of an adapted professional development intervention for preschool teachers (Social Emotional Engagement-Knowledge & Skills-Early Childhood). Social Emotional…

Little is known about how the expansion of state pre-kindergarten (pre-k) programs affects low-income children with disabilities in Head Start. Using almost 30 years of administrative data of all Head Start programs and a differences-in-differences design, this study tests the possibility that, as state pre-k differentially draws relatively more…

Head Start programs in many of the states with higher rates of children living in poverty have received less per-child funding allocations than programs in states with lower rates of children living in poverty for years. Further, the educators who teach these children are vastly underpaid, and their pay is also inequitable among states and…

Differences in children's mathematics knowledge are evident at kindergarten entry, favoring children who have greater access to economic resources. Fostering preschoolers' mathematics learning at home and in classroom settings, through games and other developmentally appropriate activities, is of great interest to educators, early childhood…

Children who know fewer words in preschool typically continue to have lower levels of vocabulary knowledge in higher grades than their peers who know more words. In fact, this difference continues to be pronounced and even widens as these children reach higher grade levels. Interventions that support vocabulary development and reading…

Two hundred ninety-four children from low-income families (58% White, 17% Latinx, 25% Black; 54% girls; M[subscript age] = 4.49 years old at study entry) were recruited from Head Start classrooms to participate in a randomized-controlled trial of the project REDI (Research-based, Developmentally Informed) preschool intervention and then followed…
