Accessibility Testing Tools

A variety of tools are available to assist with accessibility evaluation efforts. Most of the tools listed here perform automated checks on content created in a given format. While these automated checks are useful and easy to administer, they do not report on all accessibility issues. For a full assessment, you should test the functionality of your site using manual tasks, keyboard testing, and other methods. View a model testing protocol.

The IT Accessibility group at Iowa maintains this list as a service to developers and other stakeholders; please contact to make suggestions or report changes to items listed here.
