CSUN Masters of Science in Assistive Technology and Human Services

Earn the Seating and Mobility Specialist Certification.

The SMS certification recognizes demonstrated competence in seating and mobility assessment, funding resources, implementation of intervention, and outcome assessment and follow-up.

The Seating and Mobility Specialist (SMS) is a specialty certification for professionals working in seating and mobility. While the ATP is a broad-based exam covering all major areas of assistive technology, the SMS exam is focused specifically on seating, positioning, and mobility. The program is intended for clinicians, suppliers, engineers and others involved in seating and mobility service provision.


Candidates who have satisfied the exam eligibility requirements by way of an approved Exam Application, and have paid the exam fee, will receive an Authorization-to-Test (ATT) notice via email. The ATT will display the 90-day testing deadline (beginning the date of the letter) and will provide instructions for contacting Prometric to schedule the exam appointment at one of Prometric's 600+ computer-based testing centers around the world. The candidate will choose a test center, and will then select an available appointment date within his or her 90-day exam period window.

To schedule, reschedule, or cancel an appointment, candidates must call Prometric at 800-467-9582 Monday-Friday, 8:00 a.m. to 8:00 p.m. Eastern Time. Test center information is available at

Failure to schedule an exam appointment within the candidate’s 90-day exam window will result in forfeiture of the application/exam fee. The candidate will then be subject to a $100 re-exam fee to schedule the exam in a new 90-day exam window. Candidates who fail to schedule an appointment in their original exam window or the subsequent exam window will be required to submit a new application with the full application/exam fee before they can take the exam
