WCAG 2.2 is the current version, published in October 2023. It builds on WCAG 2.0 (2008) and 2.1 (2018), adding nine new success criteria with a stronger focus on cognitive accessibility and mobile interaction.
There are three levels of conformance:
- Level A — the most basic accessibility features
- Level AA — the standard referenced in most legislation worldwide, including in Australia. This is what you should aim for.
- Level AAA — the highest level, aspirational for most sites
What’s new in 2.2? The additions that matter most for nonprofits: interactive elements must be at least 24×24 pixels (easier to tap on mobile), keyboard focus can’t be hidden behind sticky headers or chat widgets, login processes can’t rely on cognitive tests like CAPTCHAs, and if a user has already entered information during a session, you shouldn’t ask for it again. These are sensible, practical requirements — most of them are just good UX.
