Students who are Black or Hispanic are now reported to be less likely to be identified as having disabilities than similarly situated students who are White. Although repeatedly replicated, this finding is often characterized as in error. I use a new statistical technique, the E-value, to quantify the likelihood that unmeasured confounding…

We used time-varying effect modelling of two very large samples of fourth-grade students (N[subscript reading] = 148,240, N[subscript mathematics] = 152,220) to investigate associations between adoption and over-time implementation of a de facto cap on special education service receipt and over-time likelihoods of disability identification from…

This study presents a longitudinal analysis of racial inequities evidenced in placement patterns in the least restrictive environment (LRE). We compared placement trends in neighborhoods and charter schools for Black and White students receiving special education services (SRSES). Drawing from the concept of "institutional isomorphism"…

This dissertation explores how federal education policies affect outcomes for special populations and their teachers. The first study uses a differences-in-differences design and data from the Stanford Education Data Archive to determine if "No Child Left Behind" (NCLB) waivers reduced district-level white-black and white-Hispanic…

To examine whether special education racial risk ratios reported by U.S. school districts are explained by district-level confounds, particularly, racial achievement gaps, we analyzed merged data (N = 1,952 districts for Black-White comparisons; N = 2,571 districts for Hispanic-White comparisons) from the U.S. Department of Education's Office of…

By 2030, most jobs will require some training beyond high school (a four-year degree, a two-year associate degree, or some type of industry credential). Too few Texas students are currently obtaining the necessary postsecondary credentials. In response to this challenge, the Texas Higher Education Coordinating Board established the 60x30TX Plan in…

Recently in a "New York Times" op-ed entitled "Is Special Education Racist?" Morgan and Farkas (2015) confront conventional wisdom that there are too many minority students in special education stating, "The real problem is that Black children are underrepresented in special education classes when compared with White…

The focus on the achievement gap has overshadowed ways in which school systems constrain student achievement through trends of racial disproportionality in areas such as school discipline, special education assignment, and juvenile justice. Using Critical Race Theory, we reframe these racial disparities as issues of institutionalized racism.…

Evidence of disparate identification of autism at national and local levels is accumulating, but there is little understanding about disparate identification of autism at the state level. This study examined trends in state-level administrative identification of autism under the Individuals with Disabilities Education Act. Prevalence rates and…

The Texas Education Agency's (TEA's) 2019 Annual Report focuses on areas of achievement based on the Agency's Strategic Priorities: (1) Recruit, Support, and Retain Teachers and Principals; (2) Build a Foundation of Reading and Math; (3) Connect High School to Career and College; and (4) Improve Low Performing Schools. A key highlight of TEA's…

This study examined prevalence and relative risk of school-based autism identification by race, and the relations of each to state characteristics. The sample was drawn from general and special education enrollment data for students ages--21 in 46 states during the 2008-2009 academic year. The results show that 1 in 228 students nationwide was…

It's a familiar refrain in American education: African-American children score lower on standardized tests, graduate high school at lower rates, and are considerably more likely to be suspended or expelled than the general population. Two recent reports, one from the Council of the Great City Schools and one from the American Institutes for…

African Americans account for approximately 12.4 percent of the United States population. They also account for approximately 79 percent of the players in the National Basketball Association. On average, African American and Hispanic students are found eligible for special education services at higher rates than their populations would suggest,…

Fifty years after "Brown v. Board of Education", school achievement remains segregated by both race and class. Despite an emphasis on reading achievement as required by No Child Left Behind, many students have serious literacy needs, even into the middle and upper grades. The purpose of this study was to ascertain ways in which middle…

Two schools in Idaho received ARRA SIG (American Recovery and Reinvestment Act School Improvement Grants) funds to enable them to implement improvement efforts. This paper describes the outcomes of these two ARRA SIG recipient schools: (1) Jefferson Middle School; and (2) Lakeside Elementary School. The experiences of this non-recipient school is…
