Resources

Official sources should always take priority for exam preparation. This page collects starting points so you can move from the conceptual material on this site into primary documents and communities.

IAAP and CPACC

International Association of Accessibility Professionals (IAAP) -- certification overview, membership, and official announcements.
CPACC Content Outline and Body of Knowledge -- available to candidates and members through the IAAP site. Review Domain weights: Disabilities & AT (~40%), Accessibility & Universal Design (~40%), Standards, Laws & Management (~20%).
Practice with the official outline: for each subtopic, write a short explanation in your own words and one real-world example.

Universal Design primary sources

Centre for Excellence in Universal Design -- The 7 Principles -- clear statements of principles and guidelines.
Center for Universal Design, North Carolina State University (historical source of the 1997 principles led by Ronald Mace).

Universal Design for Learning

CAST UDL Guidelines -- interactive Guidelines 3.0 and downloads.
CAST -- research, books, and implementation resources.

Web accessibility standards

Practical tools (for learning and checking)

WebAIM Contrast Checker -- verify text and background contrast ratios.
Browser developer tools and accessibility inspectors (Chrome, Firefox, Edge) -- practice inspecting headings, focus order, and ARIA.
Screen reader practice: NVDA (Windows), VoiceOver (macOS/iOS), TalkBack (Android). Learning the basics of one screen reader greatly improves understanding of Perceivable and Operable requirements.

Study approach suggestions

Map the domains. Create a one-page outline of CPACC Domain 1, 2, and 3 topics. Tick items as you can explain them without notes.
Connect theory to examples. For each of the 7 Principles, write one physical and one digital example from your own experience.
Teach it back. Explain UDL's three principles to a colleague or record yourself. Teaching reveals gaps quickly.
Practice multi-format notes. Use text, simple diagrams, and short audio notes -- applying UDL to your own study process.
Stay current. Confirm exam dates, fees, and any Body of Knowledge updates on the official IAAP site before you sit the exam.
