ATP, ATS and RET Certification Programs

Certification of a service provider, in any field, is the process by which a non-governmental agency or association validates an individual’s qualifications and knowledge in a defined functional or clinical area. Candidates for certification typically must meet specific requirements to be eligible for certification and those declared eligible must pass an examination.

RESNA, an interdisciplinary association of people with a common interest in technology and disability, offers national certification for three specialties:

Assistive Technology Practitioner (ATP)

Service providers who analyze needs of consumers with disabilities, assist in selection of appropriate assistive technology for  the consumer’s needs, and provide training in the use of the selected device(s). 

Assistive Technology Supplier (ATS)

Service providers who are involved with the sale and service of rehabilitation equipment or commercially available assistive technology products or devices for consumers with disabilities.

Rehabilitation Engineering Technologist (RET)

Service providers who apply engineering principles to the design, modification, customization and/or fabrication of assistive technology for persons with disabilities.

Each certification promotes a standard for recognizing qualifications and validating broad-based knowledge required as the foundation for safe and effective service in the field of assistive technology. These standards aim to enhance service provision to people with disabilities who are seeking technology applications to maximize their ability to function in their environment. The credential achieved through each certification program promotes quality assurance for the consumer, is a source of pride for the service provider, and promotes a standard of professional practice for the field. Thousands of rehabilitation engineers, occupational therapists, physical therapists, speech and hearing pathologists, suppliers, educators and other professionals have been certified.

ATP and ATS certifications are time-limited credentials that must be renewed annually. Certificants demonstrate their commitment to continuous professional development and lifelong learning by accumulating specified continuing education units (CEUs) and/or academic credits during each certification period and must meet minimum requirements for relevant work experience during that time in order to renew their certification.
