Special education is vital for many children with disabilities across the United States, as it provides necessary support that ensures they receive an appropriate education and have the opportunity to succeed. The Individuals with Disabilities Act (IDEA) is an important federal law that is meant to ensure these children have access to free and appropriate public education. As social workers and educators, it is essential to understand the laws that affect vulnerable populations in the country and how they impact families and marginalized groups. This piece aims to highlight those issues, along with offering a brief background on the IDEA.
Overview of IDEA
The Individuals with Disabilities Education Act (IDEA) is a law that ensures children with disabilities receive a free appropriate public education (About IDEA, 2017). The IDEA controls how states and public agencies provide early intervention, special education, and related services to roughly 8 million infants, toddlers, and children.

Brief History & Purpose of IDEA
For much of U.S. history, people with disabilities were largely ignored and stigmatized. Children with disabilities, in particular, were often denied access to education and learning opportunities. According to A History of the Individuals With Disabilities Education Act (2020), before 1970, U.S. schools educated only 1 in 5 children with disabilities. This began to change when President Gerald Ford signed the Education for All Handicapped Children Act into law on November 29, 1975, marking a major federal commitment to supporting the educational needs of children with disabilities. This law later became known as the Individuals with Disabilities Education Act (IDEA). Since its passage, the United States has made significant progress in developing early intervention and special education programs. By the 2022–2023 school year, over 8 million children with disabilities were receiving specialized education services tailored to their individual needs (A History of the Individuals With Disabilities Education Act, 2020).
Key Principles
The Individuals with Disabilities Education Act (IDEA) outlines six key requirements to ensure that children with disabilities receive appropriate educational support in the United States (Lipkin et al., 2015). First, it guarantees a Free Appropriate Public Education (FAPE) for all children with disabilities between the ages of 3 and 21, provided by states and local school districts. Second, it requires the identification and evaluation of all children with disabilities to determine their eligibility for special education services. Third, IDEA mandates the creation of an Individualized Education Program (IEP) for each eligible child, developed in collaboration with parents and educators to address the child's specific educational needs. Fourth, it emphasizes placement in the Least Restrictive Environment (LRE), meaning children with disabilities should learn alongside their non-disabled peers whenever possible. Fifth, the law provides procedural safeguards to protect the rights of children and families, including access to mediation and appeals. Finally, IDEA promotes active collaboration with parents, and when appropriate, the child, in making decisions related to IEP development, services, and placement, ensuring their voices are central in the educational planning process.
Who it Protects
The Individuals with Disabilities Education Act (IDEA) is designed to protect the educational rights of all children with disabilities. It requires states to provide services beginning at preschool age (3–5 years) and continuing through age 21. IDEA covers a wide range of disabilities, including intellectual disabilities; hearing impairments (including deafness); speech or language impairments; visual impairments (including blindness); emotional disturbances; orthopedic impairments; autism; traumatic brain injury; specific learning disabilities; and other health impairments. The law ensures that these children have access to appropriate educational services tailored to their individual needs. For example, a child with autism may receive services such as behavioral and speech therapy that cater towards their needs, while a child who is legally blind may have an IEP focused more on providing Braille or other assistive technology to access learning materials (Lipkin et al., 2015).
Impact on Marginalized Populations
When discussing the IDEA and its impact on children with disabilities, one cannot overlook the influence on marginalized families who have children that require special education. It is a commonly accepted fact that children of color are overrepresented in the special education population, which may be the cause of misidentification and implicit biases. As stated by the Learning Disabilities Association of America, “Disproportionality in special education placement and school discipline are issues that need to be addressed by educators and policymakers, as students of color—especially students of color with disabilities—are disproportionately subjected to exclusionary discipline and may more often be placed in segregated settings that limit their access to a rich, rigorous education,” (2020). Educators and social workers need to be aware of these differences, especially when working in racially diverse and lower-income neighborhoods, so they can provide adequate care to these children and their families.
What Can Be Done To Help?
One of the biggest challenges across all educational laws is securing adequate funding. This is no different for the IDEA, which specifically has a sub-section titled “National Activities to Improve Education of Children with Disabilities” (Part D) that provides funding to programs that are vital for the development of special education services. Unfortunately, many people don’t know about this section of the IDEA and its importance. According to Yell, M. L., & Bradley, M. R. (2024), “The Office of Special Education Programs (OSEP) has determined that Part D programs account for less than 1.7% of the national expenditure to educate students with disabilities,” which means they aren’t receiving enough funding despite their crucial role in evaluating and implementing effective practices in educating all children with disabilities. In order to effectively provide education to all children with disabilities, there should be more focus on improving funding under Part D of the IDEA. If policymakers required more funding for Part D, it could enhance training among educators, promote more research on inclusive teaching methods, and even bridge gaps between schools and families. Another positive change that could be made to the IDEA is focusing on the definition of FAPE. The definition has not been changed since 1975, when it was part of the EHA. Previously, some courts have used this lack of change in definition to justify providing a lower standard of education to children with disabilities. (Yell, M. L., & Bradley, M. R., 2024). If Congress revised the definition to align more with recent court rulings, it could reduce inconsistencies and better protect students’ rights.
