Heading Levels – Skipped or Nested (MS Word)
When headings are used correctly in MS Word, assistive technologies are not only able to convey the document’s structure, but also allow users to navigate through the document.
The Purpose of this checkpoint is to ensure that heading levels have been not been skipped. For example, a heading 1 cannot be followed by a heading 3 (without a heading 2 in-between).
CommonLook Office will display a warning message for each instance of skipped heading levels. To correct the problem, close CommonLook Office by clicking “Close and Return to Word” (the first button on the left side of the Ribbon) and edit the document to ensure no heading levels are skipped.
Note: Heading 1 should be used for the document title, Heading 2 is used to designate major sections in the document such as chapters, and Heading 3 is used for subsections within a particular chapter or major section.
