Introduction This is the seventh post in the WCAG 3.0 series. The expanded scope post looked at how far WCAG 3.0 reaches “beyond the web.” This time, I want to answer a question a lot of people keep asking me. “Should we migrate to WCAG 3.0?” Short answer up front: not yet. But there’s an important nuance to that answer. “Conformance” and “improvement” are two different conversations. Source document: This post is based on the W3C Working Draft of March 3, 2026. Drafts are generally updated on a roughly six-month cycle, so details may have shifted by the time you’re reading this. ...

↻ 2026-07-30 Updated Updated the basis document to the W3C Working Draft of March 3, 2026 — one draft newer than the version cited at publication time. Introduction This is the sixth post in the WCAG 3.0 series. This time I want to unpack what “beyond the web” actually means in practice. The earlier posts looked at structure, testing, and Assertions — now it’s time to get clear on “how far does the scope actually reach?” ...

↻ 2026-07-30 Updated This post reflects the W3C Working Draft of March 3, 2026. Foundational was renamed to Core, so related wording has been corrected, and the Assertions count (28) and their role in level determination have been updated to match the current draft. Introduction In Atomic Tests vs. Holistic Tests: A New Testing Methodology, we discussed balancing Atomic and Holistic tests. Now we need to address how we’ll “assert” and “document” these results. This is where Assertions come in. ...

It accounts for Foundational being renamed to Core, and the basis-document reference has been corrected to the current draft. Introduction When people hear “accessibility testing,” they often think of a checklist: “Does this button have alternative text?” “Is the contrast ratio high enough?” WCAG 2.2 is built around clear pass/fail checks like these. WCAG 3.0 moves toward a broader unit of evaluation, aiming to consider overall user experience quality. That shift naturally changes how we test. We now combine fine-grained checks (Atomic) with real-world contextual evaluation (Holistic). ...

↻ 2026-09-10 Updated The Working Draft of September 10, 2026 changed the conformance model again. Bronze/Silver/Gold below are no longer conformance levels. The September draft sets a single conformance line (all core requirements met) and moves the levels into reporting tiers below and above conformance. Core requirements now carry severity tags (Physical harm, Risk, Barrier, Friction), and the conformance section moved from Exploratory to Developing. The body below still reflects the March draft; the new structure is covered in What Changed in the WCAG 3 September 2026 Draft. ↻ 2026-07-30 Updated ...
