WCAG 2.1 AA, in plain terms

The conformance level most contracts specify, translated out of standards language into what you have to build.

Public sector tenders in the UAE increasingly name WCAG 2.1 level AA as a requirement. It gets written into contracts more often than it gets read. Here is what it actually asks of you.

It is not a checklist of features

WCAG is organised around four principles. Content must be perceivable, operable, understandable and robust. That framing matters, because most failures are not a missing feature — they are a working feature that only works one way.

A carousel with arrows you can click is operable. If those arrows cannot be reached by keyboard, it fails.

The requirements that catch most sites

  • Contrast. Body text needs 4.5:1 against its background. Large text and the boundaries of interface components need 3:1. This is measurable, so it is the first thing an auditor runs.
  • Keyboard access. Everything you can do with a mouse must be reachable and operable from a keyboard, in an order that makes sense.
  • Visible focus. Wherever keyboard focus lands, it must be obvious. Removing the focus outline without replacing it is one of the most common single-line failures we find.
  • Labels on inputs. A placeholder is not a label. It disappears when typing starts, and assistive technology may never announce it.
  • Reflow and zoom. The page has to stay usable at 200% zoom without horizontal scrolling or clipped content.
  • Motion. Anything that moves automatically for more than five seconds needs a way to pause it.

What 2.1 added over 2.0

Version 2.1 brought in criteria aimed at mobile and at cognitive load: orientation, pointer gestures, target size, and status messages that are announced without moving focus. If a supplier tells you their 2.0 conformance covers 2.1, it does not.

Where AA stops

AA does not require sign language for video, or 7:1 contrast, or context-sensitive help. Those sit at AAA. Specifying AAA across a whole estate is usually unrealistic; specifying AA and meeting it fully is worth considerably more than claiming AAA and missing.


Evidence, not assurances

A conformance claim is only as good as the record behind it. What survives scrutiny is a per-criterion statement of how the site was tested, by whom, and what remains open. That is the document we produce, because it is the one a procurement officer can actually use.
