What Is Significant Disproportionality?
Significant disproportionality describes the trend of overrepresentation of a specific racial/ethnic group in special education and related services.
Who Gathers Data on Significant Disproportionality?
The Office of Special Education Programs (OSEP) gathers state data on significant disproportionality [PDF]—specifically, new eligibility determinations in six disability areas:
speech or language impairment
autism
emotional disturbance
specific learning disabilities
other health impairments
intellectual disabilities
See OSEP Fast Facts: Race and Ethnicity of Children With Disabilities Served Under IDEA Part B.
How Is Significant Disproportionality Determined?
States analyze disparities among seven racial/ethnic groups that are represented by children in the state. They compare these data to those of all other children within the local education agency (LEA) across 14 different categories of analysis.
States calculate a “risk ratio” for each of the seven racial/ethnic groups, and they set a threshold. If data for a specific racial/ethnic group exceeds the state’s threshold, then this indicates significant disproportionality.
Which Factors Related to Significant Disproportionality?
The three factors that relate to significant disproportionality are:
- eligibility (or identification for special education);
- educational placements (one enrolled in special education services); and
- disciplinary action.
Factor #1: Eligibility (or identification for special education)
- Students may be over-identified or under-identified as eligible for special education services under one of 13 disability categories in the Individuals with Disabilities Education Act (IDEA).
- Speech or language impairment is one of the 13 categories in IDEA.
- Under IDEA, students may receive speech and language services based on a primary diagnosis of speech or language impairment or as a related service, secondary to another diagnosis.

Factor #2: Educational Placements (once enrolled in special education services)
- Some students do not receive a free and appropriate public education (FAPE) in the least restrictive environment (LRE).
- LRE means being educated with children who do not have disabilities “to the maximum extent appropriate” to meet the student’s specific educational needs.
- School-based SLPs and other IEP team members must consider the child’s ability to be involved in academic, nonacademic, and extracurricular activities when making placement determinations

Factor #3: Disciplinary Action
- Some students may be disproportionately subject to disciplinary action in school due to gender, race, or ethnicity.
- Students with language-learning disabilities and impairments may appear on an SLP’s caseload as early as elementary school.
- Students who demonstrate academic difficulties due to undiagnosed communication disorders may commit delinquent acts as a way to avoid academic tasks.
- Students who experience disciplinary punishment at school may become increasingly involved in the criminal justice system, which is known as the school-to-confinement pipeline.
- Students who are male, experience social and/or economic disadvantage, and come from a minoritized racial group may be overidentified as having SLI or misdiagnosed as having mental health needs or emotional disturbances.
