Many persons with disabilities must rely on the use of assistive technology to help them participate in activities of daily living, employment, and education. Acquiring this technology may require professional assistance. To ensure consumer safety, satisfaction, and optimum function in their use of assistive technology and rehabilitation services, it is important that consumers have a way of identifying qualified people who: 1) specialize in the evaluation or supply of assistive technology services and devices, and 2) can provide the necessary training on their use.

RESNA (the Rehabilitation Engineering and Assistive Technology Society of North America) has developed three credentials that recognize a demonstrated level of professional competence in the service provision of Assistive Technology: the ATP, ATS, and RET.

What is an Assistive Technology Practitioner (ATP)?

A service provider who is involved in analysis of a consumer’s needs, fitting and training in the use of a particular device.

What is an Assistive Technology Supplier (ATS)?

A service provider who is involved with the sale and service of rehab equipment, assistive technology and commercially available products or devices.

What is a Rehabilitation Engineering Technologist (RET)?

A person who applies engineering principles to the design, modification, customization and/or fabrication of assistive technology for persons with disabilities. The areas of practice for the Rehabilitation Engineering Technology encompasses job accommodations, computer access, mass/ public transportation, vehicle modifications, architectural modifications and home modifications, augmentative/ alternative communications, environmental controls, positioning devices, seating and mobility, sensory aids, and learning accommodations. An individual must obtain the ATP credential prior obtaining the RET credential.

What is the impact of the ATP, ATS, and RET Credentials on Assistive Technology?

Knowing that assistive technology (AT) professionals can hold an ATP, ATS, or RET credential empowers the consumer to be a stronger self-advocate while empowering the provider to raise the bar of professional standards and market their own professional expertise as a qualified AT professional.

The customer, whether an end user, an insurance company, or a government agency, can have confidence that an individual who is certified through RESNA offers:

A level of education and professional experience required to meet eligibility criteria

Knowledge of assistive technology, as shown by passing a credentialing exam

Professionalism and ethical practice, as prescribed by RESNA’s Standards of Practice

Professional oversight by the RESNA Professional Standards Board
