Half of kindergarten teachers split children into higher and lower ability groups for reading or math. In national data, we predicted kindergarten ability group placement using linear and ordinal logistic regression with classroom fixed effects. In fall, test scores were the best predictors of group placement, but there was bias favoring girls,…

We examined to what extent subgroups of students identified with learning disabilities (LDs; N = 630) in the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999 (ECLS-K): 1998 national longitudinal study displayed heterogeneity in longitudinal profiles of reading and mathematics achievement from first to eighth grades.…

The present study investigated the relationship between two major components of executive functioning (EF) and externalizing behavior problems (EBP) during the early elementary years. More specifically, Working Memory (WM) and Cognitive Flexibility (CF) measured in kindergarten through second grade were used to predict teacher ratings of EBP in…

We analyzed a population-based cohort of 11,780 U.S. children to identify risk and protective factors by kindergarten predictive of being frequently verbally, social, reputationally, or physically victimized during the upper elementary grades. We also stratified the analyses by biological sex. Kindergarten children displaying externalizing problem…

Approximately one in 10 children in the United States is diagnosed with attention-deficit/hyperactivity disorder (ADHD), a disability that can negatively affect academic achievement, yet relatively few children with ADHD are in special education. To better understand factors that determine which students with ADHD are in special education, we…

Students who are English Language Learners (ELLs) are at greater risk for negative school outcomes than their English proficient counterparts. Previous research has demonstrated the importance of engagement to promote academic achievement among students. However, little research has been conducted examining engagement among students who are ELLs.…

Research Findings: Using data from 3,250 participants in the Early Childhood Longitudinal Study, Birth Cohort, we used structural equation modeling to investigate whether family routines (e.g., bedtime routine, reading routine) established in preschool predict children's school readiness (i.e., academic skills, social-emotional skills, and…

Children with learning disabilities represent the largest category of students served within special education systems in schools, and are at increased risk for academic and psychosocial problems in comparison to peers without learning disabilities. While much of clinical practice and research focus has been on academic interventions,…

Recent federal, state, and district policies that have mainstreamed English language learner (ELL) students into general, English-only elementary school classrooms have raised questions among educational stakeholders about the widespread effects of these policies. Most research has focused on the outcomes of ELL students; almost nothing is known…

This study's primary purpose was to examine the relative contribution of social-behavioral predictors to reading and math skills. The study expands on Duncan et al.'s (2007) work by using longitudinal methodology from the National Institute of Child Health and Human Development's Study of Child Care and Youth Development (SECCYD) and the Early…
