Success Criterion 3.1.5 (Level AAA)
Does your site or application provide supplemental content, or lower level reading versions, for content that is above the lower secondary education level?
Why is this important
People with reading and cognitive disabilities may not be able to understand difficult or complex content that is written above a lower secondary education level (over 7 to 9 years of school).
Whom does it benefit?
As a person with dyslexia who has trouble recognizing words,
I want more readable content that is easier to decode
so that I can comprehend the information being presented.
As a person with cognitive disabilities,
I want supplemental content provided for sections of text that are more complex
so that I can better understand the information that is being presented on the web page.
What should you do?
- Write clear and concise content using short, common words and short sentences.
- If the reading level of the content is above a lower secondary education level (over 7 to 9 years of school), provide supplemental content or a lower level reading version of the content.
How do you do it?
- Create well organized sections, paragraphs and heading structures. Write short paragraphs using concise sentences. Use simple words when appropriate.
- Measure the reading level of selected passages from a page. Names and titles that cannot be changed (e.g. names of people and book, movie, and document titles) should not be included in this measurement.
If content is above the lower secondary reading level, provide supplemental material or alternative content that
is easier to decode and understand, such as:
- a text summary written at a lower level than the original content
- images to represent or help explain some of the more complex text
- a lower reading level version of the entire block of content
- audio version of the content
