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?” Important: This post is based on the WCAG 3.0 Working Draft (2026-02-20). The Draft is subject to change, and this post may be updated accordingly. ...
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. The scoring and conformance model covered in WCAG 3.0 Conformance Model: Changes After A/AA/AAA also connects with Assertions. This is because they provide a way to supplement areas not covered by quantitative tests with organizational processes and evidence. ...
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). This shift directly connects to the score-based conformance model discussed in WCAG 3.0 Conformance Model: Beyond A/AA/AAA. The weight you give each test type can change the score and the level you reach. ...
Introduction In the previous post, we looked at why WCAG 3.0 reorganized “Success Criteria” into “Outcomes.” This post focuses on changes to the conformance model. WCAG 3.0 aims for a different approach than WCAG 2.x, but it is still in the Editor’s Draft (2026-01-05) stage and is not finalized. Conformance levels, scoring approaches, and evaluation methods are still being explored. Important: This post is based on the WCAG 3.0 Editor’s Draft (2026-01-05). The draft can change at any time, and the document itself is explicitly marked as a work in progress. ...
