WCAG by level

Here are all the guidelines grouped by conformance level.

To be clear, accessibility is not a checklist or a tool, and doing everything exacly as documented here will not always guarantee an accessible, or compliant site. It's important to note that how you deliver accessibility is unique and completely dependant on your particular site content, and users.

Level A

Level A represents the lowest level of conformance and includes the most basic of web accessibility features. Every page on the internet should start by meeting this basic level of conformance.

Level AA

Level AA represents a midrange level of conformance, and includes the biggest and most common barriers for disabled users. In order to meet AA, you need to make sure you are also meeting Level A.

Level AAA

Level AAA represents the highest level of conformance and accessibility. Contrary to popular belief, level AAA is not always hard or impossible to meet. There are many technical reasons why items will be designated as AAA, but what I have experienced over time is a lot of these are just included as part of good design and usability.
