Kentucky's 13 Special Education Disability Categories: IEP Eligibility Explained

Your child has a diagnosis. Now you are wondering whether that diagnosis qualifies for an IEP. The answer depends not on the diagnosis itself but on how the disability is classified under Kentucky's special education regulations and whether it adversely affects your child's education.

How IEP Eligibility Works in Kentucky

Qualifying for an IEP requires meeting two criteria simultaneously:

1. The student has a disability that fits into one of Kentucky's 13 recognized categories under 707 KAR 1:002
2. Because of that disability, the student's educational performance is adversely affected in a way that requires specially designed instruction

A diagnosis from a pediatrician or psychologist alone does not guarantee an IEP. Medical documentation is important evidence, but the educational impact determination is made by the ARC — not the doctor. Conversely, a child can qualify for an IEP without a formal medical diagnosis if the evaluation data supports an educational disability determination.

Kentucky's 13 Disability Categories

Autism. A developmental disability significantly affecting verbal and nonverbal communication and social interaction, generally evident before age 3. Under Kentucky's regulations, autism must adversely affect educational performance to trigger IEP eligibility. Note that the Sixth Circuit, covering Kentucky, has addressed cases where a child's autism no longer adversely affects academic performance — in those cases, IDEA eligibility may not be maintained even with a confirmed diagnosis.

Deaf-Blindness. Combined hearing and visual impairments causing such severe communication and other developmental and educational needs that students cannot be accommodated in programs for either deaf or blind students alone. Rare category with highly specialized service requirements.

Developmental Delay. Used for children ages 3 through 8 who have delays in physical development, cognitive development, communication, social or emotional development, or adaptive development. Critical note: Under Kentucky regulations, a child using the Developmental Delay category must be evaluated and transitioned to a specific disability category before their ninth birthday. If your child is approaching age 9 and still categorized under Developmental Delay, a reevaluation should be scheduled to establish a specific category.

Emotional-Behavioral Disability (EBD). Characterized by one or more of the following, exhibited over a long period and to a marked degree that adversely affects educational performance: inability to learn that cannot be explained by intellectual, sensory, or health factors; inability to build or maintain satisfactory interpersonal relationships; inappropriate types of behavior or feelings under normal circumstances; a general pervasive mood of unhappiness or depression; or a tendency to develop physical symptoms or fears associated with personal or school problems. Anxiety disorders and depression often fall here.

Functional Mental Disability. Significant limitations in intellectual functioning and adaptive behavior, originating before age 18. Kentucky distinguishes between Mild Mental Disability and Functional Mental Disability based on severity of cognitive and adaptive limitations.

Hearing Impairment. Impairment in hearing, whether permanent or fluctuating, that adversely affects educational performance but is not included under Deafness. Includes students who are hard of hearing.

Mild Mental Disability. Significant limitations in intellectual functioning (generally in the mild range, IQ approximately 55-70) and adaptive behavior. Students classified under MMD in Kentucky pursue modified curricula and have different graduation pathway considerations.

Multiple Disabilities. Concomitant impairments (such as intellectual disability-blindness or intellectual disability-orthopedic impairment), the combination of which causes such severe educational needs that students cannot be served in special education programs solely for one of the impairments.

Orthopedic Impairment. Severe orthopedic impairment that adversely affects educational performance. Includes impairments caused by congenital anomaly, disease, or other causes such as cerebral palsy, amputations, or fractures or burns that cause contractures.

Other Health Impairment (OHI). Having limited strength, vitality, or alertness due to chronic or acute health problems that adversely affect educational performance. ADHD, sickle cell anemia, asthma, epilepsy, and other chronic conditions frequently qualify here. OHI is one of the most commonly used categories in Kentucky IEPs, particularly for students with ADHD whose inattention adversely affects their ability to access the curriculum.

Specific Learning Disability (SLD). A disorder in one or more of the basic psychological processes involved in understanding or using language, spoken or written, that adversely affects the ability to listen, think, speak, read, write, spell, or do mathematical calculations. Dyslexia, dysgraphia, dyscalculia, and auditory processing disorders typically fall here. SLD is the most common disability category nationally and in Kentucky.

Speech or Language Impairment. Communication disorder such as stuttering, impaired articulation, language impairment, or voice impairment that adversely affects educational performance. One of the most commonly identified categories in early elementary grades.

Traumatic Brain Injury (TBI). An acquired injury to the brain caused by an external physical force, resulting in total or partial functional disability or psychosocial impairment, or both, that adversely affects educational performance.

Visual Impairment Including Blindness. Impairment in vision that, even with correction, adversely affects educational performance. Includes both partial sight and blindness.

Why the Disability Category Matters

The disability category affects more than just the IEP label. It can influence:

• What types of assessments the district uses in the evaluation
• Which specialists become involved in service delivery (orientation and mobility specialists for visual impairment, audiologists for hearing impairment)
• Whether the student is eligible for the alternate assessment pathway (only applicable for students with the most significant cognitive disabilities)
• What accommodations are typically appropriate on state assessments
• How the student's transition goals are framed

If you believe the ARC categorized your child under the wrong disability category — for instance, categorizing a student with ADHD under Specific Learning Disability when the primary need is OHI-related attention and alertness — that misclassification can affect which services are considered appropriate. Requesting a reevaluation is the mechanism for correcting it.

What to Do If the ARC Finds No Eligible Category

If the ARC evaluates your child and concludes they do not meet criteria for any of the 13 disability categories, they must issue Prior Written Notice explaining the basis for that conclusion. The PWN should cite the specific evaluation data, identify what category was considered and rejected, and explain why the eligibility criteria were not met.

Read that document carefully. If the evaluation did not assess all areas of suspected disability, or if the data cited does not match the results you received from outside evaluators, you have grounds to request an Independent Educational Evaluation at public expense.

Even if IDEA eligibility is denied, your child may still qualify for a 504 Plan under Section 504 of the Rehabilitation Act, which has a broader eligibility standard and does not require specially designed instruction — only documentation of a physical or mental impairment that substantially limits a major life activity including learning.

The Kentucky IEP & 504 Blueprint includes a guide to each disability category's eligibility criteria in Kentucky, common evaluation tools used for each category, and a decision framework for understanding whether your child is more likely to qualify under IDEA or Section 504.
