Test Your Site
This page provides information about accessibility testing tools that can be helpful in detecting accessibility concerns on websites and web applications. We recommend you test against both Section 508 and WCAG 2.0 to ensure long-term conformance with accessibility guidelines and create the best experience for users of the site or application.
AMP (Accessibility Management Platform) is MU’s automated accessibility testing tool by SSB Bart Group. AMP can assist with measuring the accessibility of University affiliated websites, web applications, and electronic documents.
This free tool is available for students, faculty, and staff on the Columbia campus.
To access AMP, log into the AMP tool and choose the “Sign on with University User ID” link.
To learn more about, AMP go to help.missouri.edu and search for “AMP“.
SSB Bart has also produced a series of short videos that include demos of assistive technology and discussion of common accessibility challenges. You can view them on SSB Bart’s YouTube Channel.

The Web accessibility evaluation checkers listed above can perform automated testing of the web pages and provides information about whether the accessibility guidelines are met and reports the issues. Automated testing needs to be combined with manual testing to complete the process for accessibility checking. Screen readers are programs used by people with visual impairments that provide an auditory representation of what is on the screen. Testing with a screen reader can help achieve manual testing.
- JAWS screen reader (free download) – Job Access With Speech (JAWS) is a commonly used robust screen reader for Microsoft’s Windows and has a free demo mode. To perform testing of web pages use Internet Explorer and Firefox. To get started, we recommend WebAIM’s Using JAWS to Evaluate Web Accessibility guide.
