WCAG Levels
WCAG Level A
The minimum baseline — 31 success criteria addressing the most critical barriers. Includes alt text (1.1.1), keyboard access (2.1.1), page titles (2.4.2), and error identification (3.3.1). Level A alone is not sufficient for legal compliance. (WCAG 2.2 marks 4.1.1 Parsing as obsolete, so it is no longer counted.)
In plain terms
The most basic accessibility level — the bare minimum. Important, but not enough on its own to satisfy most laws.
Why this matters
Level A covers the most fundamental barriers — the ones that make content completely unusable for some people. Meeting only Level A isn't enough for the law, but failing it means basic, severe exclusion.
