Guidance:

Purpose

The purpose of this success criterion is to ensure that readers with difficulty processing complex text have an alternative in simpler prose.

How to Meet

To meet this success criterion, publishers must either author their content so that it has a low readability score or provide alternative content in simpler prose for all text that uses complex language.

Whether this success criterion is attainable will depend on the nature of the publication. It may not be realistic, for example, for advanced textbooks and other works that deal with complex topics.
