This dissertation researched the scope of mathematics achievement disparities in the United States and how these disparities can be minimized through a self-efficacy lens. To answer pertinent research questions with data from the National Assessment of Educational Progress (NAEP) 2019 mathematics assessment in Grades 4, 8, and 12, gap analyses,…

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 opt-out movement, a grassroots coalition of opposition to high-stakes tests that are used to sort students, evaluate teachers, and rank schools, has the largest participation on Long Island, New York, where approximately 50% of the eligible students in grades three to eight opted out of the English Language Arts (ELA) and Mathematics tests in…

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…

Peer victimization is a widespread and heterogeneous phenomenon, especially during the transition to middle school, and is associated with numerous negative consequences. However, previous research is limited by variable-centric analyses and data manipulations that either fail to capture or mask the complexity of peer victimization many students…

Racial, ethnic, and socioeconomic disparities in autism identification negatively affect educational interventions for students identified with autism. The purpose of this qualitative ethnographic study was to gain insight into educational interventions aiding in eliminating racial, ethnic, and socioeconomic disparities through the implementation…

Abundant empirical research points to a significant number of students not going to school across the United States. Further yet, there exists strong research consensus that absenteeism predicts negative and persistent academic outcomes for students. LEAs and related stakeholders have rightly adopted measurement and intervention on student…

A multisite cluster-randomized trial (by school) was conducted to examine the effects of a combined mental health literacy and dialectical behavior therapy skills program implemented by teachers on three protective factors related to social and emotional well-being. The sample of eight schools that were randomly assigned to intervention included…

Whether students of color are more or less likely to be identified as having disabilities than similarly situated students who are White in U.S. states with histories of de jure and de facto racial segregation is currently unknown. Unadjusted analyses of large samples of students attending elementary and middle schools in the U.S. South yielded…

In the fall of 2019, 3,355 10-year-old students in the Houston Independent School District (HISD) students participated in the Study on Social and Emotional Skills (SSES), part of an international effort led by the Organization for Economic Cooperation and Development (OECD), with Houston serving as the only U.S. site. This report provides a…

The Individuals with Disabilities Education Act stresses the importance of educating students with disabilities (SWDs) in the least restrictive environment, often with peers who do not have disabilities. Prior research has examined the extent to which SWDs are included in general education classrooms, but not the characteristics of the peers with…

This report examines how students are performing across the entire 2020-2021 school year in reading and mathematics during the pandemic. Based on insights from millions of student assessments, the report explores key questions effected by COVID-19 in education, including: (1) How much did students grow during the 2020-2021 school year compared…
