What is AT?

Assistive technology (AT) includes thousands of simple to complex devices that enable persons with disabilities to perform tasks they are unable to accomplish or have great difficulty accomplishing. 

These products may be used at home, in the work place, in the classroom and in the community to reduce barriers and empower personal abilities. 

Examples include hearing aids, communication devices, computers and specialized software, home or vehicle modifications and more.. 

AT devices must be accompanied by AT services which assist an individual with a disability in the selection, purchase or use of an assistive technology device.
