Digital accessibility severity and prioritisation

Use the Digital accessibility severity prioritisation guide to categorise digital accessibility issues based on impact on users and prioritise fixes to ensure compliance with Web Content Accessibility Guidelines (WCAG).

Classifying accessibility issues will help allocate resources to ensure the most impactful barriers are removed first and improve usability. Meeting these guidelines ensures everyone can use our digital services and platforms.

Severity categoryDescription
Critical Must fix issues that make the website or app unusable for some users with disabilities. If not fixed, some users won't be able to use the website or app at all.
High Website or app is very difficult to use for some users.
MediumWebsite or app is inconvenient but not impossible to use, hard to complete tasks and likely to be confusing.
LowWebsite or app is mostly usable, but these issues result in some inconvenience. It's not impossible or significantly harder to use, complete tasks and understand, but users are likely to experience frustration, and it will not be completely easy to use or meet the WCAG standards. These need to be fixed but are not urgent.
