Individuals with Disabilities Education Act definition:
Assistive technology devices or services — The IEP team must always consider the child’s need for assistive technology devices or services. If a child needs such devices or services, they must be listed in the IEP and the school must make sure that the devices and services are made available to the child at no cost to the child or the child’s parents. In some cases, the school may purchase assistive technology devices for use in the home or outside the school.
