IDEA Disability Category

Traumatic brain injury

An acquired brain injury from an external force that affects learning.

An educational classification, not a medical diagnosis. A medical or clinical diagnosis does not automatically qualify a child for an IEP, and a child can qualify under IDEA without one. Eligibility is an educational team decision based on evaluation data. These are educational classifications, not medical diagnoses.

What it means

Traumatic brain injury, or TBI, means an acquired injury to the brain caused by an external physical force, resulting in a full or partial functional disability or psychosocial impairment, or both, that adversely affects educational performance. It can affect areas such as thinking, memory, attention, reasoning, judgment, problem-solving, language, sensory and motor skills, behavior, and information processing. It does not apply to brain injuries that are congenital or degenerative, or caused by birth trauma.

What it can include

  • Injury from an external force such as a fall or accident
  • Changes in memory, attention, or reasoning
  • Changes in behavior, motor, or sensory skills

How it affects school

Because needs can change during recovery, supports are reviewed often and may include accommodations for memory and fatigue, therapy services, and a gradual return-to-learn plan.

How IEP eligibility works

To qualify for an IEP under this category, an evaluation team generally must find three things to be true:

  • A qualifying disability. The child is evaluated and found to have one or more of the 13 disability categories defined under IDEA.
  • An adverse effect on learning. The disability must adversely affect the child educational performance. A label by itself is not enough.
  • A need for specially designed instruction. Because of the disability, the child needs special education and related services to access their education.

Common questions

Does a concussion count as a TBI under IDEA?

It can, if it results from an external force and adversely affects educational performance so that the child needs specially designed instruction. The team evaluates the specific impact.

What if my child needs change as they recover?

The IEP can and should be reviewed and adjusted as the child recovers, since needs after a brain injury often change over time.
