About the ATP Exam

CSUN Masters of Science in Assistive Technology and Human Services

The ATP examination features 200 multiple choice questions that test competency in the broad field of assistive technology practice.  

The four-hour exam is administered via computer at Prometric test centers around the world. The exam is currently delivered in English.

Accommodations are available for candidates with special needs that comply with the American Disabilities Act (ADA). Candidates with special needs must request accommodations when they submit the Certification Application. Please contact RESNA to discuss available ADA accomodations.  

The exam is preceded by a 10-minute tutorial which provides instruction on navigating through the exam. At the end of the exam, candidates will receive a preliminary Pass/Fail grade.

For candidates who fail the exam, the score report will show the overall percentage score earned and will include diagnostic information about the candidate's performance in each of the five major knowledge domains from the Exam Content Outline. There is a 90-day waiting period after taking the test before one can re-apply with the re-take application, after which the test taker can retake the test at the reduced rate ($250) for up to one year after the original test was taken.
