Traumatic Brain Injury means a student has had a closed brain injury caused by external force that affects how they learn or function in school. This injury may happen because of an accident, fall, or other physical injury to the head. A brain injury can affect thinking, memory, behavior, speech, or movement. To qualify under this category, a student must have a medical diagnosis from a licensed physician. Students with TBI may need special education services and supports to help them succeed in school.
