Automated Accessibility Checkers

A Word of Caution
Automated, accessibility testing tools provide a good baseline check for accessibility of HTML web pages, PDFs and Microsoft Office 2010 documents, but the documents still need a human to check the pages and ask these questions:
- Are headings used to give the document structure?
- Are embedded media and any interactive widgets on the page, keyboard accessible?
- Does the ALT text for images and graphics clearly represent the meaning the instructor wants to convey with the image?
- Is the navigation easy to follow and understand?
Microsoft Word 2010 and 2013 and Microsoft PowerPoint 2010 and 2013 for Windows have built-in accessibility checkers. It's a great way to do a automated check on your document, but it doesn't catch everything. It can't think, so it can't tell you if something should be formatted as a heading for example. So make sure to do a manual check in addition to using this tool.
Microsoft Office 2010 and 2013 Accessibility Checker
Please Note: The accessibility checker only checks .docx files
- Go to the File tab.
- Select Info from the sidebar menu.
- Click on the Check for Issues button.
- Select Check Accessibility from the drop-down list.
The Accessibility Checker panel will open to theright of the document. The accessibility checker provides you with a list of errors, warnings and tips. When you click on an error or warning, instructions on how to fix it appear below in "Additional Information".
There are a few different web page accessibility checkers, but in order to check web pages that require a log-in, such as D2L does, you will need a browser based checker, such as the Web AIM WAVE accessibility add-on for the Firefox browser.
- Download & Install the WAVE toolbar
- Open the D2L page in its own window by clicking on the Open in a new window icon.
- Right-click on the page in the new window, and select WAVE, then choose "Errors, Features, and Alerts" to see what accessibility errors you have on the page.
- Error icons in green, red, yellow and blue will appear on the page. If you hover over an error icon, more information on the error will appear.
- Return to the original D2L page, and open the D2L editor to repair the problems you found.
There's a lot more you can do with this toolbar too, but this is how you do an accessibility error check with it. For more information on the toolbar, see the Web AIM website.
