Success Criterion 3.1.4 (Level AAA)
Does your website/application allow users to access abbreviations and acronyms in an expanded form?
Why is this important
Abbreviations and acronyms can have multiple meanings and pronunciations that are inconsistent with the usual language rules, which can confuse users and may also not be conveyed correctly through assistive technology. It is important that the meaning of the abbreviation is clear to the user and that they can access it’s expanded form.
Whom does it benefit?
As a person with low vision relying on a screen
I want to be able to understand the meaning of an abbreviation without context
so that I can read through the information being presented without having to trace back through what I have already read for clarity.
As a person who has trouble decoding words
I want to be able to easily identify the word and it’s meaning
so that I can read through the information being presented without being tripped up by abbreviations.
What should you do?
- Review your content for abbreviations and acronyms
- Include access to the extended form of the abbreviation or acronym
- Enable users to search your content/web application/website to find the expanded form of the abbreviation or acronym when it’s not provided in context
