WCAG

WCAG, the Web Content Accessibility Guidelines, is the international standard for web accessibility published by the W3C Web Accessibility Initiative (WAI), governing how digital content must be designed and built so that people with disabilities can perceive, operate, understand, and use it. The current published standard is WCAG 2.2 (October 2023), which adds nine new success criteria to WCAG 2.1 (June 2018), which itself added 17 criteria to WCAG 2.0 (December 2008). WCAG 3.0 is in draft and represents a more substantial restructuring rather than an incremental extension. The standard is organized around four principles — Perceivable, Operable, Understandable, Robust (POUR) — broken into 13 guidelines and 86 testable success criteria (in WCAG 2.2) at three conformance levels: A (essential, minimum), AA (the practical legal target for most jurisdictions), and AAA (enhanced, rarely required wholesale). Specific criteria cover image alt text, color contrast ratios (4.5:1 minimum for normal text at AA), keyboard accessibility, predictable navigation, captions for video, time limits on interactions, focus visibility, and dozens more. The legal context: WCAG 2.1 AA is the de facto compliance target for the Americans with Disabilities Act (Section 508 explicitly references WCAG 2.0 AA), the EU's European Accessibility Act (effective June 2025 for many consumer-facing products), the EU's Web Accessibility Directive (already in force for public sector), the UK Equality Act, the Accessible Canada Act, and increasingly comparable laws in Australia, Japan, and Israel. Lawsuits under the ADA Title III for inaccessible websites and apps have exploded — over 4,000 federal cases per year in the US since 2021. Practical evaluation tooling includes axe-core (Deque Systems, the dominant open-source automated checker built into most browser dev tools), Lighthouse (Google, built into Chrome DevTools), WAVE (WebAIM), Pa11y (CI/CD-friendly), and the commercial offerings from Deque (axe DevTools, axe Auditor), Level Access, AudioEye, and Siteimprove. Automated tools catch roughly 30-40% of WCAG violations; the remaining 60-70% require manual review and assistive-technology testing. For Digital Experience Platforms, WCAG compliance is not optional — the experience must be accessible to every audience, by both law and ethical mandate.

WCAG compliance built into a Magic Quadrant DXP: Centralpoint has remediated WCAG-compliant experiences for 25 years across regulated client industries — the accessibility discipline is foundational, not optional, to Gartner Magic Quadrant DXP positioning where the experience must reach every user. WCAG enforcement runs on-premise, lineage is audit-graded, and accessible experiences deploy through one line of JavaScript.
