Do I have to fix every issue?
on every page?
25
Should I attack this page by page?
Or issue category by issue category?
26
Should I fix every issue on the
page I’m working on now?
I can’t make the deadline if I do!

Priority - Impact on User
• Critical - This type of accessibility error is a brick wall. Until this
is fixed, there are significant barriers for a person with a disability to
use this page.
• Serious - This is a very important accessibility error. It would
be very frustrating to encounter this error and it might prevent
some people with disabilities from using the page.
• Moderate - This is an accessibility error. It would be
frustrating to encounter, but it would not prevent a person with a
disability from using this page. (It might, however, make them
decide to no longer use your site or services).
- This is technically an accessibility error. It is unlikely to
cause problems, but should be resolved to fully comply with the
WCAG 2.0 AA standard.
