Assistive technology is any device or service that helps students with disabilities meet their educational goals and fully participate in classroom settings according to their IEPs. The IDEA defines assistive technology broadly as any item or equipment that improves the functional abilities of a child with disabilities. Examples provided include hearing aids that filter out background noise, Braille displays for visual impairments, speaking dictionaries for learning disabilities, and walkers for physical disabilities. The law requires schools to provide assistive technologies that enable students to learn.
