Practice Tests Will Be Available Soon
We are preparing practice tests for this exam. Please check back shortly.
The CPACC exam does not ask you to write a line of code, yet it has become the credential accessibility hiring managers look for first. Created by the International Association of Accessibility Professionals (IAAP), it tests whether you actually understand disability, not whether you can fix an ARIA attribute. That distinction trips up a surprising number of candidates who arrive expecting a technical exam and instead face 100 questions on disability models, legal frameworks from multiple countries, and the reasoning behind universal design. This page gives you free practice questions built around the CPACC Body of Knowledge, organized the way the actual exam is weighted.
The exam is built from three domains, and IAAP publishes the weighting for each:
Domain 1: Disabilities, Challenges, and Assistive Technologies (40%). This is the largest single portion of the exam, and it covers far more than "know the categories of disability." You need to characterize theoretical models of disability (medical, social, biopsychosocial, and others), explain their strengths and blind spots, and apply them to scenarios. You also need working knowledge of assistive technology: screen readers, switch access, eye-gaze systems, and how each interacts with sensory, motor, cognitive, and speech disabilities.
Domain 2: Accessibility and Universal Design (40%). Also worth 40%, this domain covers the POUR principles from WCAG (Perceivable, Operable, Understandable, Robust) alongside the seven principles of Universal Design. The exam frequently tests whether you can distinguish an individual accommodation from a universal design solution applied at the system level, which sounds simple until you're staring at two plausible-looking answer choices under time pressure.
Domain 3: Standards, Laws, and Management Strategies (20%). The smallest domain by weight but a common source of missed points, because it is genuinely international. Expect questions that go beyond the ADA into frameworks like the UN Convention on the Rights of Persons with Disabilities, the European Accessibility Act, and country-specific legislation such as Canada's Accessibility for Ontarians with Disabilities Act. Candidates who study only U.S. law lose points here.
(Domain weightings above are published in IAAP's official CPACC Body of Knowledge and Content Outline; treat any percentage breakdown you see elsewhere as approximate unless it cites that source directly.)
The CPACC draws a broader crowd than most IT certifications. Because it requires no coding knowledge, it attracts UX and product designers who need to defend accessibility decisions to stakeholders, project managers who own accessibility compliance without writing the fix themselves, procurement and legal staff evaluating vendor accessibility claims, and QA testers who want a foundational credential before moving into the more technical Web Accessibility Specialist (WAS) exam. IAAP recommends at least a year of accessibility-related experience, or a clear account of how your current role intersects with accessibility work, though this is a stated expectation rather than a hard prerequisite checked before registration.
The CPACC is a proctored, closed-book exam of 100 multiple-choice questions, each with a single correct answer, and a passing score around 65%. IAAP does not report your score as a raw percentage; results come back as a scaled score, so you won't know exactly which questions cost you the pass. This matters for how you practice: aim well above the minimum passing threshold during preparation, since you have no visibility into partial credit or near-misses on the thing.
Two format details catch people off guard. First, several questions are scenario-based rather than definitional: instead of "What is the medical model of disability?" you'll get a short case study and have to identify which model or principle best explains it. Rote memorization of definitions gets you only partway there. Second, because the exam is genuinely international, some questions reference laws or standards outside your home country. If you've only ever worked under U.S. accessibility law, budget extra study time for Domain 3.
Work the practice questions in the same 40/40/20 proportion as the exam rather than treating all three domains equally, since that's how your actual score will be weighted. When you miss a question in Domain 1, don't just note the correct answer — go back and identify which theoretical model or disability category you confused it with, because the exam frequently pairs similar-sounding concepts as distractors. For Domain 2 questions, practice explaining out loud why a universal design solution differs from an individual accommodation in the same scenario; that reasoning skill transfers directly to the exam's scenario-based items. Time yourself on a full 100-question set at least once before test day so the pacing feels familiar under the time limit.
The most common error is treating this as a WCAG technical exam and under-preparing for Domain 1's disability models and Domain 3's legal landscape, which together make up 60% of the score. Second, candidates frequently confuse Universal Design with accessibility generally; Universal Design is the broader design philosophy of building for the widest range of users from the start, while accessibility often refers more narrowly to removing specific barriers for people with disabilities. The exam tests that you know the difference. Third, candidates default to U.S.-only legal knowledge and get caught by questions referencing the UN CRPD, EN 301 549, or the European Accessibility Act. Finally, some candidates skim the CPACC Body of Knowledge instead of working through it chapter by chapter; IAAP writes the exam directly from that document, and skipping sections tends to show up as gaps on exam day.
Read the official CPACC Body of Knowledge cover to cover before touching third-party study guides, since IAAP writes exam content only from material found there. When you hit the disability models section, build yourself a comparison table of medical, social, and biopsychosocial models side by side, because the exam likes to test the boundaries between them rather than asking you to define each in isolation. For Domain 3, don't try to memorize every law; instead, group them by the type of protection they offer (employment, digital access, physical environment) so you can reason your way to an answer even for a law you haven't specifically studied. If you're coming from a technical background, resist the urge to over-study WCAG success criteria at the expense of disability models. The exam leans conceptual, not technical.
Work through the practice questions on this page in domain order, starting with Disabilities, Challenges, and Assistive Technologies since it carries the most weight. Once you're consistently scoring above 80% across all three domains in practice, you're in reasonable shape to schedule your proctored exam date through IAAP.
