A groundbreaking decade-spanning analysis of state and federal data has illuminated a stark socioeconomic divide in how educational support for children with disabilities is accessed, revealing that affluent families are significantly more likely to secure accommodations under Section 504 of the Rehabilitation Act of 1973 than their lower-income counterparts. Conversely, the study found that students from low-income backgrounds are disproportionately represented in the realm of individualized education programs (IEPs), a more comprehensive federal support system.
The research, released in January by a team of academics led by Nick Ainsworth, a doctoral student at the University of California, Irvine, examined millions of academic and tax records from Oregon students between the 2008-09 and 2018-19 school years. This meticulous linkage of educational outcomes with household income data provided an unprecedented granular view of access to federal disability services.
Key Findings: A Tale of Two Support Systems
The study’s most striking revelation is the divergence in access to Section 504 plans, which mandate reasonable accommodations to ensure students with disabilities have equal access to educational opportunities. Ainsworth and his colleagues discovered that students from families in the top income brackets were nearly twice as likely to be granted a 504 plan compared to those from the lowest income brackets. Specifically, 2.9% of students from the highest income quintile received a 504 plan, while only 1.5% from the lowest income quintile did.
This finding directly challenges the intended universal nature of Section 504, a civil rights law designed to prevent discrimination on the basis of disability. While Section 504 plans are generally considered less intensive than IEPs, offering accommodations like extra time on tests, preferential seating, or reduced homework, their accessibility appears to be heavily influenced by socioeconomic status.
In contrast, the study found a reversed dynamic for IEPs, the more robust framework established by the Individuals with Disabilities Education Act (IDEA). IEPs provide specialized instruction tailored to a student’s unique learning needs, which can include services outside the general education classroom. The data indicated that one-quarter of the most disadvantaged students had an IEP, a proportion more than three times greater than that of the wealthiest students. This suggests that while low-income families are more likely to access the comprehensive support of IEPs, they may be missing out on the potentially more accessible, yet less intensive, accommodations provided under Section 504.
Origins of the Study: A Pandemic-Era Spark
Ainsworth’s interest in this disparity was ignited during the COVID-19 pandemic, a period marked by a dramatic decline in special education evaluations nationwide. As he and his colleagues delved into pre-pandemic trends, they began to observe significant differences in how households across the income spectrum accessed federal disability services.
"We looked across the income distribution and started to see these large differences," Ainsworth stated. "We had some hypotheses about what that would look like with respect to 504 plans, but we did not expect to see those differences favoring high-income students."
The research team’s initial hypotheses may not have fully anticipated the extent of the income-based disparity in 504 plan access, but their findings resonate with long-standing concerns voiced by education observers. These suspicions often centered on the notion that Section 504, with its less stringent eligibility criteria and fewer mandated services compared to IEPs, could be leveraged by families with the resources and know-how to secure academic advantages.
A History of Suspicion: Previous Investigations
The implications of Ainsworth’s study are amplified by prior investigative journalism that hinted at similar trends. In 2019, separate reports from The Wall Street Journal and The New York Times highlighted a conspicuous overrepresentation of students with 504 plans in school districts with higher average incomes. These reports raised concerns that some parents might be exploiting the program to gain what were perceived as unearned academic perks for their children, particularly in the context of high-stakes standardized tests like the SAT and ACT, where extra time is a common accommodation.
The intense competition for top academic scores and coveted college admissions slots has fostered an environment where even minor advantages can be perceived as critical. This pressure extends beyond high school, as a growing number of undergraduates at prestigious universities report conditions like anxiety and ADHD, which can qualify for accommodations. However, experts have grappled with whether this rise reflects genuine need, or if the system’s design inadvertently incentivizes exploitation, leaving more genuinely needy children underserved.
Understanding the Tradeoffs: IEPs vs. Section 504
The distinct legal frameworks and funding mechanisms underpinning IEPs and Section 504 plans are crucial to understanding the observed disparities.
The Individuals with Disabilities Education Act (IDEA) and IEPs
Established in 1975, IDEA mandates that public schools provide a Free Appropriate Public Education (FAPE) to eligible children with disabilities. IDEA outlines 13 specific categories of disability that qualify a child for special education services. The federal government supports these services through annual grants to states, totaling over $15 billion in fiscal year 2025. This federal funding directly supports the development and implementation of IEPs, which are legally binding documents outlining a student’s educational goals, services, and accommodations.
Paul Morgan, a professor at the University of Albany specializing in disability classification, explained that IEPs are designed to provide specialized instruction geared toward individual learning goals, potentially involving placement outside of general education. The presence of federal funding and a defined set of eligibility categories provides a clearer pathway and incentive for schools to identify and serve students requiring these comprehensive supports.
Section 504 of the Rehabilitation Act and 504 Plans
Section 504, enacted as part of the Rehabilitation Act of 1973, is a broader civil rights law prohibiting discrimination based on disability in programs receiving federal funding. It ensures that students with disabilities have equal access to educational opportunities. Unlike IDEA, Section 504 is not directly tied to federal funding for special education services. Instead, schools are required to make "reasonable accommodations" to provide equal access. These accommodations, often provided at no direct cost to the federal government, can include modifications to assignments, testing procedures, or classroom environments.
Christopher Cleveland, an assistant professor of education at Brown University and a co-author of the study, noted that the incentives for schools to initiate the 504 process are "probably less clear." He elaborated, "Many school leaders feel that they’re in a high-pressure situation to figure out the resources of special education versus local, in-state dollars. Whereas the 504 plan decisions seem like they’re more subject to advocacy on the part of families."
This lack of direct federal funding for 504 accommodations places a greater onus on families to advocate for their children. Parents with greater financial resources, more time, and experience navigating bureaucratic systems are better positioned to pursue these evaluations and secure necessary supports. The need for potentially costly neuropsychological evaluations, which may not always be fully covered by insurance, further accentuates this advantage for affluent families.
Navigating the System: Advocacy and Expertise
Miriam Nunberg, a former attorney for the Department of Education’s Office of Civil Rights and now an education rights consultant in New York City, emphasized the proactive role parents must play, especially for high-achieving students whose academic performance might mask underlying learning difficulties. She pointed to a growing ecosystem of lawyers, professional advocates, tutors, and clinical evaluators who can guide parents through the process. While these services come at a significant cost, they can be indispensable, particularly in jurisdictions where school district-provided evaluations face considerable delays due to staffing shortages.
"When kids are pulling As and Bs, school staff generally aren’t referring them to assessments, whether for 504s or IEPs," Nunberg explained. "So it really has to come from the family—and that’s where you need to have the ability to educate yourself, or hire someone to help you with it."
The College Admissions Conundrum
The allure of academic advantages, particularly in the fiercely competitive landscape of college admissions, is a significant factor influencing parental engagement with disability services. Ben Lovett, a professor of psychology and education at Columbia University’s Teachers College, found the study’s finding of higher IEP prevalence among lower-income students plausible, given the known correlation between poverty and disability. However, he acknowledged that the overrepresentation of 504 plans among higher-income students was "harder to understand."
Lovett posited three potential explanations for this disparity:
- Parental Advocacy: Affluent parents may be actively pushing for 504 plans that are not strictly educationally necessary.
- Susceptibility to Certain Conditions: Children from higher-income families might be more susceptible to conditions like mood or anxiety disorders, which are not always traditionally addressed within the special education framework but can qualify for 504 accommodations.
- Navigational Challenges: Families with the neediest learners may face greater obstacles in navigating the complex system to access services.
"Only additional research that audits 504 plans and investigates the evidence of disability for each student can really determine the degree to which these three factors explain the disparities," Lovett stated, underscoring the need for further investigation.
The SAT Connection
The socioeconomic divide in 504 plan access appears to widen as students progress through middle and high school, precisely when academic demands intensify. The prospect of securing extra time on standardized tests, which are crucial for college admissions, could be a powerful motivator for families to seek any available advantage.
A separate study published in March by Tiffany Liu, a Princeton doctoral candidate, provided further suggestive evidence. This research found a notable increase in 504 plan enrollments in 2017, following a policy change by the College Board that allowed for the automatic honoring of school-based accommodations for SAT test-takers. This uptick was most pronounced in wealthier school districts.
While acknowledging that some parents may seek unwarranted advantages, Nunberg stressed that it is more common to encounter bright students genuinely struggling with focus and executive function issues, often exacerbated by parental or systemic pressure. "What I see much more often are kids who are brilliant and have a lot of pressure put on them by their parents, or themselves, or the system at large, and who are literally staying up all night to achieve high grades," she lamented.
Broader Implications and Future Directions
The findings from Ainsworth’s study raise critical questions about equity and access within the special education system. While the system is designed to be a safety net, the data suggests that its accessibility is not uniform across socioeconomic lines. The divergence in access to Section 504 plans, in particular, highlights a potential loophole that may disproportionately benefit privileged students, while students from lower-income backgrounds may be more reliant on the more intensive, but perhaps less accessible, IEP pathway.
Morgan concluded that there is substantial unmet need for disability services in K-12 schools. He also acknowledged the reality of parental ambition in a highly competitive environment. "I imagine there is abuse or manipulation of the system, including by parents who view it as a way for their child to get additional support," he stated. "Especially for some selective colleges, things have gotten so extremely cutthroat that you’d want to give your kid any benefit you could."
The study’s implications extend to policymakers, educators, and parents alike. Ensuring equitable access to educational support for all children with disabilities, regardless of their socioeconomic background, requires a deeper understanding of the systemic factors at play and a commitment to addressing any identified disparities. Further research, as suggested by Lovett, is crucial to fully disentangle the motivations and systemic influences driving these patterns and to inform policy interventions aimed at creating a more just and equitable educational landscape.
