Accessibility Checker
Use Word’s built-in accessibility checker to check for common issues. Note, that these tools may not catch all possible accessibility issues.
In the Accessibility pane select Keep accessibility checker running while I work checkbox to see a real-time accessibility message in the bottom status bar. Click Accessibility: Investigate at any time to open the Accessibility pane.
Checker Results
Like any automated tool, Word’s accessibility checker will not catch all accessibility issues. Here is a summary of what it does look for and how well it catches those issues:
| Element checked | Reliability of checker |
|---|---|
| Structure and use of heading styles | Poor.
Will show if there are no headings on a long document but doesn’t flag issues on shorter documents. A single heading is enough to pass the checker even though the document remains inaccessible. It cannot test the logic of the heading structure. Use View > Navigation Pane > Document Map/Headings to verify heading structure. |
| Colour | Moderate.
Can find poor colour contrast but cannot tell if colour has been used as a sole indicator for information. |
| Use of images | Moderate.
Will find images that have neither Alt text, nor are marked as decorative as well as those where the Alt text is just the file name. But it cannot identify whether the Alt text is appropriate or even meaningful. It will find images that are not in line with the text. In-line images may not be as aesthetically pleasing but they are easier for screen readers to find. |
| Links | Poor.
It does not check for link text. |
| Plain English | Poor.
It does not check for this, but you can check yourself by switching on the readability stats as described in the section on Understandable Content. |
| Tables | Fair.
It finds whether the table has the Header row marked. It may warn if tables have split or merged cells. |
| Miscellaneous | Poor.
Does not check text justification, videos for captions, or form labels. |
