Built around the Body of Knowledge
- Follows the official syllabus. IAAP says every exam question is written from the Body of Knowledge, so the guide follows it section by section and names the pages each chapter covers.
- Weighted like the exam. Each mock exam has 100 questions: 40 from Domain One, 40 from Domain Two and 20 from Domain Three, the weights IAAP publishes.
- Explanations that teach. Every question says why the right answer is right, why each wrong answer is wrong, and which Body of Knowledge page to reread.
- Honest about the gaps. The Body of Knowledge dates from 2023. Where a figure, standard or law has changed, or the text contains a slip, the guide tells you what it says and what is true today.
What you get
- Chapters
- Every section of IAAP's CPACC Body of Knowledge (October 2023, Version 4.0) rewritten as a structured course: comparison tables, memory aids, the points that are easy to confuse, and key terms. Each chapter names the Body of Knowledge pages it covers. Mark chapters as done to track your progress.
- Mock exams
- Two timed 100-question mock exams weighted 40% Domain One, 40% Domain Two and 20% Domain Three. Choose standard time, time and a half, double time or no timer, flag questions, and review every answer at the end.
- Topic practice
- 506 original questions in all, grouped by section, with the answer, a full explanation and the Body of Knowledge page after each one. A missed-questions list keeps everything you got wrong until you get it right.
- Flashcards
- 313 cards for the definitions, laws and lists you need to recall, with a still-learning pile.
- What has changed
- A chapter listing 55 places where the Body of Knowledge is out of date or contains a slip, each checked against the primary source in November 2026.
- Your progress, everywhere
- Progress, scores and flashcard marks are saved to your account, so you can switch between laptop and phone. Built to WCAG 2.2 AA: keyboard and screen reader friendly, light and dark modes.
Sample question
At one city library, staff bring out a portable ramp whenever a patron who uses a wheelchair asks for it. The new branch across town is designed from the start so that every entrance and floor can be reached without steps. Which approach does the new branch reflect?
- Universal design
- Reasonable accommodation
- Assistive technology
- Equivalent facilitation
Show the answer
Answer: Universal design.
The new branch was planned so that as many people as possible can use it without any adaptation, which is universal design. The ramp brought out on request at the old branch is an accommodation made for one identified person. Assistive technology is a device or system a person uses, not a property of a building. Equivalent facilitation is a term from accessibility standards for an alternative design that gives equal or greater access, which is not what the scenario describes.
Body of Knowledge reference: Domain Two A, page 36.

Frequently Asked Questions
Is this affiliated with IAAP?
No. This is an independent online course from Accessibility.build. It is not affiliated with, approved by or endorsed by the International Association of Accessibility Professionals (IAAP), and we are not an IAAP Approved Certification Preparation Provider. CPACC is a certification of IAAP. IAAP's own free Body of Knowledge and Content Outline are the official starting points, and we recommend you download them from IAAP.
Are these real exam questions?
No. IAAP exam content is confidential, and we have not used or seen it. Every question in this course is original and written from IAAP's public Body of Knowledge, which IAAP says is the source all exam questions are written from. None is taken from, or tries to recreate, an actual exam question.
How accurate is it?
Each question was answered independently, without the answer key, and checked against the Body of Knowledge page it cites before release, then checked again after any revision. Facts that go beyond the Body of Knowledge, such as the names of the WCAG guidelines or the Principles of Universal Design, were checked against the primary source (W3C, the Centre for Excellence in Universal Design, CAST, the UN, WHO, official government sites). Where the Body of Knowledge is out of date or contains a slip, the guide says so and gives the source. If you find an error, tell us and we will correct it.
Which version of the Body of Knowledge does it follow?
The CPACC Body of Knowledge dated October 2023, Version 4.0, which is the version IAAP publishes as of November 2026. If IAAP releases a newer Body of Knowledge, study its changes as well, because this edition will not cover them.
Will it tell me whether I would pass?
No, and nothing can. IAAP reports results as pass or fail on a scaled score from 200 to 800, with 600 as the passing mark, and does not publish the percentage of questions you need. The practice app shows your score by domain so you can see where to study. As our own rule of thumb, keep practising any domain where you score under 80% on fresh questions.
Does it guarantee a pass?
No. No preparation product can, and IAAP says the same of every course. The course is designed to cover the whole Body of Knowledge and give you realistic practice; your experience and study time do the rest.
How do I access the course?
Everything is on Accessibility.build. Sign in with a free account, buy a licence, and the course opens straight away in your browser on any device. Your progress, mock exam scores and flashcard marks are saved to your account. There is nothing to download or install.
