Attention-deficit/hyperactivity disorder (ADHD) is America's most common childhood disorder. Although an ADHD diagnosis can bring positives, recent research uncovers potential negatives associated with diagnosis. This study examines understudied racial-ethnic heterogeneity in the relationships between an early elementary school ADHD…

Purpose: The purpose of this journal-ready dissertation was to determine the degree to which ethnicity/race and economic status of Texas Grade 3 students is related to their mathematics achievement. In the first study, the degree to which ethnic/racial (i.e., Asian, White, Hispanic, Black) differences might be present in the mathematics…

While teaching summer school may require similar skills as reading intervention during the year, rarely are summer school instructors reading specialists. To support these instructors providing high quality instruction, this research study examined the impact of the 95 Phonics Booster Bundle: Summer School Edition (SSE). The SSE is a set of 25…

This research study analyzed the impact of an early college readiness program (ECRP) on students' academic performance on the State of Texas Assessments of Academic Readiness (STAAR) reading and mathematics assessments in Grades 3, 4, and 5. ECRP is a college readiness system designed to support students to reach postsecondary education. The ECRP…

This study examines the relationship between perceived stress, nonverbal cognitive functioning, and statewide academic scores in both Latinx and European American elementary students in rural school districts. A total of 44 third graders participated in the study, including 13 Latinx students and 31 European American (EA) students. Perceived…

Is under-representation of Black, Latinx, English learners (EL), and students from economically challenging communities in gifted programs due to inequality in early academic achievement or bias in the gifted identification process? Using three-level multilevel logistic models, we examine the degree to which the disparities in gifted…

Past research extensively documents inequalities in educational opportunity and achievement by students' race/ethnicity or socioeconomic status (SES). Less scholarship focuses on how race/ethnicity and SES interact and jointly contribute to educational inequalities. We advance this burgeoning line of scholarship by charting math achievement…

Purpose: The purpose of this journal-ready dissertation was to examine the extent to which differences were present by student demographic characteristic in the reading achievement of Texas Grade 3 students. In the first article, the extent to which the economic status (i.e., Poor, Not Poor) of Grade 3 underrepresented boys in Texas is related to…

Nearly one in five U.S. students attends a rural school, yet we know very little about achievement gaps and academic growth in rural schools. This study leverages a unique dataset that includes longitudinal test scores for more than five million 3rd to 8th grade students in approximately 17,000 public schools across the 50 states, including…

We examine access to effective teachers for low-income students in 26 geographically dispersed school districts over a 5-year period. We measure teacher effectiveness using a value-added model that accounts for measurement error in prior test scores and peer effects. Differences between the average value added of teachers of high- and low-income…

Ethnoracial inequality in educational achievement and attainment is a long-standing feature of the American education system. For example, national reading assessments show that White fourth graders scored nearly a standard deviation higher than Black or Hispanic students on average in 2015 (NCES, 2015). The measurement and analysis of differences…

We draw on novel district-level test score data to describe novel approaches for measuring ethnoracial achievement gaps and assessing trends toward achievement equity from 2009 to 2016. Using SEDA data, we estimate gap trends for each grade over time in each district. We measure trends in both within-district gaps--comparing Black or Hispanic to…

Despite considerable reform activity surrounding K-12 education over the past 20 years, racial and socioeconomic disparities among students who achieve at advanced levels have received little attention. This study examined how excellence gaps, defined as differences in performance at the 90th percentile of subgroups, change over time and their…

Are parental inputs complements or substitutes to education quality? Using variation induced by identification into a gifted and talented (GT) program, I find no aggregate effects on parental behavior as a result of their child's access to a higher quality education. However, there are heterogeneous effects. Non-minority parents decrease…

Purpose: The purpose of this study was to examine how well a kindergarten dynamic assessment of decoding predicts future reading difficulty at 2nd, 3rd, 4th, and 5th grade and to determine whether the dynamic assessment improves the predictive validity of traditional static kindergarten reading measures. Method: With a small variation in sample…
