Similar to previous rulings of the ADA, which led to more accessible buildings, all state and local government web content and mobile apps must also be made accessible to the public. But how is accessibility measured online?
The Justice Department decided to rely on a widely accepted standard for accessibility known as WCAG, or the Web Content Accessibility Guidelines–specifically WCAG 2.1, Level AA.
This documented set of rules and recommendations has been used for years now as a measure for accessibility compliance. It includes topics such as setting proper color contrast, requiring text to accompany images, keeping text legible and much more.
Most automated tools for measuring accessibility also rely on WCAG standards, such as the free WAVE or aXe plugins, or Google Lighthouse. Paid site monitoring tools such as SiteImprove or DubBot also use WCAG standards. If you've not do so before, try running your site through one of these tools and you can discover some areas of improvement for your own organization!
The "2.1" in the new rule simply refers to a version of WCAG (most recent is 2.2), while "Level AA" refers to the strictness of how the rule is applied. Level AAA is the most restrictive, while Level A is the least.
