What Is ADS?

ADS logoADS stands for Accessible Document Specialist. This is a technical credential for accessibility professionals who have regular hands-on experience with creating accessible electronic documents and remediating inaccessible electronic documents. Electronic documents in this case refers to ones that are created in word processing, spreadsheets, presentations, or desktop publishing programs.

Who Should Take It?

The ADS is the ideal credential for accessibility practitioners and specialists with a minimum 1-2 years' experience who function in one of many team roles related to accessible document authoring, remediation, training, policy, and advocacy of accessible document solutions.

Just a few examples are: accessibility professionals whose jobs require in-depth knowledge of ICT accessibility standards, document remediation specialists, accessible media service providers, UX designers and testers, QA professionals, and web content managers and administrators, though there are many other relevant roles.

  1. The Document Accessibility Package
    Enroll Now
  2. ADS Content Outline
  3. ADS Body of Knowledge Document (BOK)
  4. The resource links included within the BOK Document


The Deque Document Accessibility Specialist package currently addresses parts I, II, and some of part III of the exam content outline, but does not cover topics in parts IV and V of the outline. To fully prepare for the ADS exam, refer to the ADS Body of Knowledge, and seek outside sources about the topics not in the Deque courses.

Use all of the resources listed to maximize your preparedness to pass the exam. Do not rely on a single resource as being an exhaustive and all-inclusive preparation material.

How Long Does It Take to Prepare?

The courses in the Document Accessibility Package take approximately 10 to 20 hours to complete.

The IAAP recommends planning to spend between 30 and 80 hours total to prepare.

Is There a Practice Exam?

The IAAP has not yet released any sample questions for the ADS Exam.

Deque's courses include small quizzes to test your comprehension, but these are not practice exam questions and do not represent the format or difficulty level of the actual exam.

How Much Does It Cost?
