Assistive technology (AT) refers to any device or service that helps students with disabilities participate in education. AT includes devices like text-to-speech software, hearing aids, and wheelchairs, as well as services like evaluating students' needs and training users. The Individuals with Disabilities Education Act requires schools to consider and provide AT if needed for a free appropriate public education. AT benefits students with various disabilities including hearing, visual, learning, and physical impairments by helping them access instruction and materials.
