Write content that is easily readable and matches the reading level of your intended audience. Word's Readability Statistics tool offers valuable insights, including average sentences per paragraph and the percentage of passive voice sentences.

The Web Content Accessibility Guidelines suggest writing at a lower secondary education level, a Level AAA guideline. However, this level of strict compliance may not be suitable for all documents. For instance, content for an advanced college chemistry class may exceed the reading level appropriate for high school freshmen.
