What is the CPACC certification?
The CPACC (Certified Professional in Accessibility Core Competencies) is the foundational credential offered by the International Association of Accessibility Professionals (IAAP). It demonstrates broad, cross-disciplinary knowledge of disabilities, accessibility and universal design, and the standards, laws, and management strategies that govern accessible products and services.
Crucially, the CPACC is not a technical exam. It does not require coding or hands-on testing. It is ideal for people who manage, plan, procure, or champion accessibility — project managers, content authors, designers, policy and compliance staff, and anyone starting an accessibility career. If you want a technical, code-level credential, that is the separate WAS (Web Accessibility Specialist) exam. Earn both while valid and you receive IAAP's highest credential, the CPWA. (See our CPACC vs WAS vs CPWA guide.)
The three CPACC domains explained
The CPACC Body of Knowledge (BoK), last updated in 2023, is organised into three domains. Knowing roughly how each is weighted helps you spend your study time wisely.
1. Disabilities, Challenges, and Assistive Technologies (~40%)
The largest domain. Expect questions on the major categories of disability — visual, auditory, motor/mobility, cognitive, speech, and more — how each affects a person's interaction with digital and physical environments, and the assistive technologies people use (screen readers, magnifiers, switch devices, captions, and so on). Learn disabilities by their functional impact, not just their name.
2. Accessibility and Universal Design (~40%)
Equally weighted. This covers the principles of universal design, accessible design practices across web, documents, hardware, and the built environment, and the benefits of inclusive design for everyone. Be comfortable with the 7 Principles of Universal Design and the difference between accessibility, usability, and universal design.
3. Standards, Laws, and Management Strategies (~20%)
The smallest domain, but easy points if you prepare. Know the key standards (WCAG, EN 301 549, Section 508) and laws across regions (ADA, AODA, the European Accessibility Act, and others), plus how organisations build and sustain accessibility programs through policy, procurement, and governance.
Who can take the CPACC?
IAAP asks that candidates have one year of accessibility experience, or be in a new or changing role with some responsibility for accessibility. If you have less than a year, you will simply be asked to describe your background and goals related to the credential. In practice the CPACC is the most beginner-friendly accessibility certification, which is exactly why it is the recommended starting point.
A proven 6–8 week study plan
IAAP recommends planning for 5–10 hours a week over 6–8 weeks. Here is a simple structure that works:
- Weeks 1–2 — Domain 1. Read the BoK section on disabilities and assistive technologies. Make a one-line summary of each disability category and the technologies that support it.
- Weeks 3–4 — Domain 2. Study universal design and accessible design practices. Memorise the 7 Principles of Universal Design and connect each to a real example.
- Week 5 — Domain 3. Learn the standards and laws. Build a quick comparison table (region → law → what it requires).
- Weeks 6–8 — Practice and review. Take timed practice questions daily, review every wrong answer until you understand why, and revisit your weakest domain.
The single highest-value habit is active recall through practice questions — testing yourself, not just re-reading. That is what moves knowledge into long-term memory and builds exam-day speed.
