Extending work documenting historical resource inequities across U.S. schools, we examined how school financial and social resources mediate the relationship between family income and student achievement, and tested how these associations varied by race and ethnicity. Merging administrative school data sources to a nationally representative sample…

Although the trajectories of children's social skills have been examined across biological sexes, less research has examined these patterns for racially and ethnically diverse children in the United States. The purpose of this study was to estimate the longitudinal growth trajectories of social skills, while examining the influence of biological…

Teachers' expectations of student capabilities can meaningfully affect future achievement. However, the consistency of teachers' expectations over time and their differential impact by student gender and ethnicity have not been thoroughly investigated in the context of students' reading achievement.

Racial/ethnic and economic school segregation represent pervasive instantiations and perpetuators of educational inequity in the United States. Although the U.S. is becoming increasingly racially and ethnically diverse, schools are racially/ethnically isolated. Rising income and wealth inequity are also exacerbating economic school segregation.…

Attention-deficit/hyperactivity disorder (ADHD) overdiagnosis and overtreatment unnecessarily exposes children to potential harm and contributes to provider and community skepticism toward those with moderate or severe symptoms and significant impairments, resulting in less supportive care. Yet, which sociodemographic groups of children are…

Currently 15 percent of U.S. students receive special education services, a widespread intensive intervention with variable effects on students. Spurred by changes in federal policy, many states and districts have begun adopting the Response to Intervention (RTI) approach to identifying students to receive special education services. RTI seeks to…

We analyzed a population-based cohort (N = 10,922) to investigate the onset and stability of racial and ethnic disparities in advanced (i.e., above the 90th percentile) science and mathematics achievement during elementary school as well as the antecedent, opportunity, and propensity factors that explained these disparities. About 13% to 16% of…

This Education Leadership Portfolio's (ELP) improvement goal was to reduce student chronic absence at West Seaford Elementary School (WSES), a K-2 public school in the Seaford School District (SSD), where I serve as principal. Significant levels of student chronic absence have been and remain common at WSES, and--according to national and state…

Using an explanatory sequential mixed method, this study investigated the impact of the employment of attendance agents in the Detroit Public Schools Community District on decreasing chronic absenteeism and improving attendance rates from kindergarten to fifth grade for different subgroups of students. The study also investigated the perceptions…
