The extent to which reading achievement is causally impacted by eligibility for special education services due to a learning disability (LD) or speech or language impairment (SLI) is currently unclear. In this registered report, we analyzed U.S. national data from the Early Childhood Longitudinal Study--Kindergarten Cohort of 2010-2011 (ECLS-K:…

We examined the association of students' ability to transition on a daily basis (horizontal transitions) as reported by teachers with academic achievement as mediated by the summer Extended School Year (ESY) services received. Transitions from summer break to re-entry in the fall are referred to as a vertical transition. We examined these…

Programs that improve teaching effectiveness represent a core strategy to improve student educational outcomes and close student achievement gaps. This article compiles empirical values of intraclass correlations for designing effective and efficient experimental studies evaluating the effects of these programs. The Early Childhood Longitudinal…

Policymakers, child care providers, and parents face tradeoffs in determining how much to spend on child care, including how many hours to purchase, and the features of programs that might influence quality. Given these tradeoffs, it is useful to understand what constitutes quality, the cost of care features associated with quality, the effects of…

Purpose: Parent engagement is a critical component of optimizing services for young children with disabilities, including those with language disorders. Without training, however, many parents may lack the knowledge and skills to effectively facilitate their children's language development during the essential early childhood years. The Parents…

The present study used the Early Childhood Longitudinal Study, Kindergarten Class of 2011 (ECLS-K:2011) to examine the bidirectionality and co-occurrence between math achievement and behavioral outcomes of upper elementary school students. We analyzed the cross-lagged relations across four groups of students who had different initiating statuses…

"Pre-K Mathematics" is a supplemental mathematics program focusing on a range of mathematical concepts to help develop children's informal mathematical knowledge. The "Pre-K Mathematics" program includes teacher-led, small-group mathematics activities that are engaging and hands-on, as well as caregiver-child activities that…

Studies examining seasonal variation in academic skills for children have focused on learning loss or stagnation during the summer, particularly for students from low-income or minoritized racial and ethnic backgrounds. In this study, we expand the literature to focus on another student population that may be susceptible to summer learning loss:…

Background/Context: The early school years are an important time for building family-school relationships (Sibley & Dearing, 2014). As such, family engagement is a top priority of organizations that serve young children, such as Head Start. Children whose parents report being involved in their school demonstrate greater social competence and…

The purpose of this quantitative study was to analyze the ECLS-K:2011 longitudinal study to determine the impact the mother's education has on her child's kindergarten academic performance, growth and attainment from kindergarten through fifth grade, and the background characteristics that affect child academic development. This study employed a…

Background/Context: As of Fall 2021, approximately 7.3 million students between the ages 6 to 21 were served under the Individuals with Disabilities Education Act, which accounts for approximately 15%of students in that age range (U.S. Department of Education, 2022). Students with disabilities receiving special education services are guaranteed a…

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…

The current study investigated the prevalence and outcomes related to Head Start (HS) children's dual enrollment in state-funded prekindergarten (state Pre-K) using a secondary analysis of a statewide integrated administrative dataset (N = 2,986). It also explored whether a program partnership between HS and the local school district (within the…

Student absenteeism is a barrier to learning and an issue that requires policy intervention. Students with disabilities are of particular concern, as they miss school more often than students in any other demographic group. Affecting a key attribute of school structures, policies promoting full-day kindergarten began as an effort to improve…

The present study examined the effect of children's enrollment in U.S. dual-language immersion (DLI) programs in first grade on English development across five years, using the Early Childhood Longitudinal Study, Kindergarten Class of 2011 (ECLS-K:2011) database. Propensity score matching was used to create comparable groups of DLI and non-DLI…
