Whether and to what extent kindergarten childrens executive functions (EF) constitute promising targets of early intervention is currently unclear. This study examined whether kindergarten childrens EF predicted their second-grade academic achievement and behavior. This was done using (a) a longitudinal and nationally representative sample (N = 8,920, Mage  = 97.6 months), (b) multiple measures of EF, academic achievement, and behavior, and (c) extensive statistical control including for domain-specific and domain-general lagged dependent variables. All three measures of EF-working memory, cognitive flexibility, and inhibitory control-positively and significantly predicted reading, mathematics, and science achievement. In addition, inhibitory control negatively predicted both externalizing and internalizing problem behaviors. Childrens EF constitute promising targets of experimentally evaluated interventions for increasing academic and behavioral functioning.

Purpose: We sought to identify factors predictive of or associated with receipt of speech/language services during early childhood. We did so by analyzing data from the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B; Andreassen & Fletcher, 2005), a nationally representative dataset maintained by the U.S. Department of Education. We addressed two research questions of particular importance to speech-language pathology practice and policy. First, do early vocabulary delays increase children's likelihood of receiving speech/language services? Second, are minority children systematically less likely to receive these services than otherwise similar White children? Method: Multivariate logistic regression analyses were performed for a population-based sample of 9,600 children and families participating in the ECLS-B. Results: Expressive vocabulary delays by 24 months of age were strongly associated with and predictive of children's receipt of speech/language services at 24, 48, and 60 months of age (adjusted odds ratio range = 4.32-16.60). Black children were less likely to receive speech/language services than otherwise similar White children at 24, 48, and 60 months of age (adjusted odds ratio range = 0.42-0.55). Lower socioeconomic status children and those whose parental primary language was other than English were also less likely to receive services. Being born with very low birth weight also significantly increased children's receipt of services at 24, 48, and 60 months of age. Conclusion: Expressive vocabulary delays at 24 months of age increase children's risk for later speech/language services. Increased use of culturally and linguistically sensitive practices may help racial/ethnic minority children access needed services.

We examined the age of onset, over-time dynamics, and mechanisms underlying science achievement gaps in U.S. elementary and middle schools. To do so, we estimated multilevel growth models that included as predictors children's own general knowledge, reading and mathematics achievement, behavioral self-regulation, sociodemographics, other child- and family-level characteristics (e.g., parenting quality), and school-level characteristics (e.g., racial, ethnic, and economic composition; school academic climate). Analyses of a longitudinal sample of 7,757 children indicated large gaps in general knowledge already evident at kindergarten entry. Kindergarten general knowledge was the strongest predictor of first-grade general knowledge, which in turn was the strongest predictor of children's science achievement from third to eighth grade. Large science achievement gaps were evident when science achievement measures first became available in third grade. These gaps persisted until at least the end of eighth grade. Most or all of the observed science achievement gaps were explained by the study's many predictors. Efforts to address science achievement gaps in the United States likely require intensified early intervention efforts, particularly those delivered before the primary grades. If unaddressed, science achievement gaps emerge by kindergarten and continue until at least the end of eighth grade. [This article was published in "Educational Researcher" (EJ1091880).]

PURPOSE: This study was designed to (a) identify sociodemographic, pregnancy and birth, family health, and parenting and child care risk factors for being a late talker at 24 months of age; (b) determine whether late talkers continue to have low vocabulary at 48 months; and (c) investigate whether being a late talker plays a unique role in childrens school readiness at 60 months. METHOD: We analyzed data from the Early Childhood Longitudinal Study, a population-based sample of 9,600 children. Data were gathered when the children were 9, 24, 48, and 60 months old. RESULTS: The risk of being a late talker at 24 months was significantly associated with being a boy, lower socioeconomic status, being a nonsingleton, older maternal age at birth, moderately low birth weight, lower quality parenting, receipt of day care for less than 10 hr/week, and attention problems. Being a late talker increased childrens risk of having low vocabulary at 48 months and low school readiness at 60 months. Family socioeconomic status had the largest and most profound effect on childrens school readiness. CONCLUSIONS: Limited vocabulary knowledge at 24 and 48 months is uniquely predictive of later school readiness. Young children with low vocabularies require additional supports prior to school entry.

Children with attention-deficit/hyperactivity disorder (ADHD) are known to exhibit significantly lower academic and social functioning than other children. Yet the field currently lacks knowledge about specific impairment trajectories experienced by children with ADHD, which may constrain early screening and intervention effectiveness. Data were analyzed from a nationally representative U.S. cohort in the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (ECLS-K) for 590 children (72.7 % male) whose parents reported a formal diagnosis of ADHD. Childrens math, reading, and interpersonal skills were assessed at 5 time points between kindergarten and fifth grade. Growth mixture model analyses indicated 4 latent trajectory classes for reading, 8 classes for math, and 4 classes for interpersonal skills. Membership in reading and math trajectory classes was strongly related; overlaps with interpersonal skills classes were weaker. Trajectory class membership was correlated with demographic characteristics and behavioral functioning. Children with ADHD display substantial heterogeneity in their reading, math, and interpersonal growth trajectories, with some groups of children especially likely to display relatively severe levels of academic and social impairment over time. Early screening and intervention to address impairment, particularly reading difficulties, among kindergarten students with ADHD is warranted.

We analyzed two nationally representative, longitudinal data sets of U.S. children to identify risk factors for persistent mathematics difficulties (PMD). Results indicated that children from low socioeconomic households are at elevated risk of PMD at 48 and 60 months of age, as are children with cognitive delays, identified developmental delays or disabilities, and vocabulary difficulties. In contrast, children attending preschool either in Head Start or non-Head Start classrooms are at initially lower risk of PMD. Kindergarten-aged children experiencing either low socioeconomic status or mathematics difficulties are at greatest risk for PMD across third, fifth, and eighth grades. Also at risk for PMD between third and eighth grades are children displaying reading difficulties or inattention and other learning-related behaviors problems, children with identified disabilities, and those who are retained. Educationally relevant and potentially malleable factors for decreasing young childrens risk for PMD may include increasing childrens access to preschool, decreasing their risk of experiencing vocabulary or reading difficulties, and avoiding use of grade retention.

We used population-based, longitudinal data to investigate the relation between mathematics instructional practices used by 1st grade teachers in the U.S. and the mathematics achievement of their students. Factor analysis identified four types of instructional activities (i.e., teacher-directed, student-centered, manipulatives/calculators, movement/music) and eight types of specific skills taught (e.g., adding two-digit numbers). First-grade students were then classified into five groups on the basis of their fall and/or spring of kindergarten mathematics achievement-three groups with mathematics difficulties (MD) and two without MD. Regression analysis indicated that a higher percentage of MD students in 1st grade classrooms was associated with greater use by teachers of manipulatives/calculators and movement/music to teach mathematics. Yet follow-up analysis for each of the MD and non-MD groups indicated that only teacher-directed instruction was significantly associated with the achievement of students with MD (covariate-adjusted ESs = .05-.07). The largest predicted effect for a specific instructional practice was for routine practice and drill. In contrast, for both groups of non-MD students, teacher-directed and student-centered instruction had approximately equal, statistically significant positive predicted effects (covariate-adjusted ESs = .03-.04). First-grade teachers in the U.S. may need to increase their use of teacher-directed instruction if they are to raise the mathematics achievement of students with MD.

We investigated whether and to what extent minority children attending elementary and middle schools in the U.S. are over- or under-identified as disabled and so disproportionately represented in special education. To address existing limitations in the field's knowledge base, we (a) analyzed multi-year longitudinal data, (b) used hazard modeling to estimate over-time dynamics of disability identification across five specific conditions, and (c) extensively corrected for child-, family-, and school-level potential confounding variables (e.g., child-level academic achievement and behavior, family-level socioeconomic status, school-level state location). Despite long-standing and on-going federal legislative and policy efforts to reduce minority over-representation in special education, our analyses indicated that this has not been occurring in the U.S. Instead, minority children are less likely than otherwise similar White, English-speaking children to be identified as disabled and so receive special education services. From kindergarten entry to at least the end of middle school, racial and ethnic minority children are less likely than otherwise similar White children to be identified as having (a) learning disabilities, (b) speech or language impairments, (c) intellectual disabilities, (d) health impairments, or (d) emotional disturbances. Language minority children are less likely to be identified as having (a) specific learning disabilities or (b) speech or language impairments.

Data were analyzed from a population-based, longitudinal sample of 8,650 U.S. children to (a) identify factors associated with or predictive of oral vocabulary size at 24 months of age and (b) evaluate whether oral vocabulary size is uniquely predictive of academic and behavioral functioning at kindergarten entry. Children from higher socioeconomic status households, females, and those experiencing higher quality parenting had larger oral vocabularies. Children born with very low birth weight or from households where the mother had health problems had smaller oral vocabularies. Even after extensive covariate adjustment, 24-month-old children with larger oral vocabularies displayed greater reading and mathematics achievement, increased behavioral self-regulation, and fewer externalizing and internalizing problem behaviors at kindergarten entry.

BACKGROUND: Whether and to what extent racial/ethnic disparities in attention-deficit/hyperactivity disorder (ADHD) diagnosis occur by kindergarten entry is currently unknown. We investigated risk factors associated with an ADHD diagnosis by kindergarten entry generally, and specifically whether racial/ethnic disparities in ADHD diagnosis occur by this very early time period. METHODS: Secondary analysis of data from children enrolled in the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B), a large, nationally representative cohort of U.S. children born in 2001. Data include information from birth certificates, parent and teacher questionnaires, and in-person developmental assessments conducted with children at intervals from 9 months through kindergarten entry. The analytic sample included children enrolled in the ECLS-B at the 60-month assessment (N = 6,550). RESULTS: Black children in the United States were 70% (1 - OR of .30) less likely to receive an ADHD diagnosis than otherwise similar White children. Hispanic children initially appeared to be underdiagnosed for ADHD. However, their disparity with Whites became statistically nonsignificant after controlling for whether a language other than English was primarily spoken in the home. Analyses of kindergarten teacher-reported classroom behavior indicated that neither Black nor Hispanic children displayed less frequent ADHD-related behaviors than Whites. CONCLUSIONS: Although they are not less likely to display ADHD-related behaviors, children who are Black or being raised in households where non-English is primarily spoken are less likely than otherwise similar White children to be diagnosed with ADHD in the US.

Federal legislation and policy increasingly seek to address minority overrepresentation in special education due to concerns that U.S. schools are misidentifying children as disabled based on their race or ethnicity. Yet whether and to what extent this is occurring is currently in dispute. We estimated racial disparities in disability identification using very large (e.g., Ns = 183,570, 165,540, and 48,560) student-level, nationally representative data sets and multivariate logistic regression including school fixed effects models along with tabulations of percentage with a disability among racial or ethnic groups across academic achievement deciles. Among children who were otherwise similar in their academic achievement, poverty exposure, gender, and English language learner status, racial or ethnic minority children were consistently "less" likely than White children to be identified as having disabilities. Minority children's disability underidentification was evident (a) in elementary, middle, and high school; (b) across racially diverse groups and specific disability conditions; and (c) throughout the achievement distribution. Contrary to federal regulatory and policy efforts, minority children have been less likely than otherwise similarly achieving White children to receive special education services in the United States since at least 2003.

We investigated whether and to what extent children who are racial-ethnic minorities are disproportionately represented in early intervention and/or early childhood special education (EI/ECSE). We did so by analyzing a large sample of 48-month-olds (N = 7,950) participating in the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B), a nationally representative data set of children born in the United States in 2001. Multivariate logistic regression analyses indicate that boys (odds ratio [OR] = 1.66), children born at very low birth weight (OR = 3.98) or with congenital anomalies (OR = 2.17), and children engaging in externalizing problem behaviors (OR = 1.10) are more likely to be represented in EI/ECSE. Children from low-socioeconomic-status households (OR = 0.48), those displaying greater numeracy or receptive language knowledge (ORs = 0.96 and 0.76, respectively), and children being raised in households where a language other than English is primarily spoken (OR = 0.39) are less likely to be represented in EI/ECSE. Statistical control for these and an extensive set of additional factors related to cognitive and behavioral functioning indicated that 48-month-old children who are Black (OR = 0.24) or Asian (OR = 0.32) are disproportionately underrepresented in EI/ECSE in the United States.

Purpose: This article provides information about the Head Start Family and Children Experiences Survey (FACES). It also presents the findings of a study that capitalizes on the strengths of the data from FACES to investigate the impact of child and family characteristics, speech-language impairment, and the home literacy environment on the language and early literacy outcomes of children from low-income families. Method: Data from the FACES 1997 cohort were used in this study. Variables included in the analysis were child and family characteristics (e.g., age, gender, ethnicity, etc.); parent report of speech-language impairment; frequency of home literacy activities; and children's scores on vocabulary, letter-word identification, and early reading assessments. Results: The results revealed that children's vocabulary abilities in Head Start were affected by maternal education, ethnicity, and the frequency of home literacy activities, and children's letter-word identification abilities were impacted by maternal education and the child's gender and age. Additionally, children's reading abilities in kindergarten were predicted by ethnicity, speech-language impairment, and the home literacy environment, as well as by children's vocabulary and letter-word identification abilities in Head Start. Conclusion: The findings demonstrate the unique contributions that the home literacy environment and the presence of speech-language impairment during preschool make in children's early reading outcomes.

We examined three questions. First, do reading difficulties increase children's risk of behavioral difficulties? Second, do behavioral difficulties increase children's risk of reading difficulties? Third, do mathematics difficulties increase children's risk of reading or behavioral difficulties? We investigated these questions using (a) a sample of 9,324 children followed from third to fifth grade as they participated in a nationally representative dataset, (b) multilevel logistic regression modeling, and (c) statistical control for many potential confounds. Results indicated that poor readers in third grade were significantly more likely to display poor task management, poor self-control, poor interpersonal skills, internalizing behavior problems, and externalizing behavior problems in fifth grade (odds ratio [OR] range = 1.30-1.57). Statistically controlling for a prior history of reading difficulties, children with poor mathematics skills in third grade were also significantly more likely to display poor task management, poor interpersonal skills, internalizing behavior problems, and reading difficulties in fifth grade (OR range = 1.38-5.14). In contrast, only those children exhibiting poor task management, but not other types of problem behaviors, in third grade were more likely to be poor readers in fifth grade (OR = 1.49). Poor readers in third grade were extremely likely to still be poor readers in fifth grade (OR = 19.69). [ABSTRACT FROM AUTHOR]
