This article offers guidance on ways to create Microsoft Word documents to make them more accessible to users with disabilities. Because many files are often viewed electronically, governments and industries around the world are implementing policies that require electronic and information technology to be accessible to people with disabilities. For example, the amended Section 508 of the United States Rehabilitation Act of 1973 requires Federal agencies to make all of their electronic and information technology accessible.
Starting with Microsoft Office 2010 a new tool for Word, Excel, and PowerPoint called the Accessibility Checker is available that you can use to check your Word documents for any issues that might make it challenging for a user with a disability. To learn more, see Accessibility Checker.
