Accessible Websites & Web Apps
Preparing to Test for Accessibility
Components of an Accessibility Test
- Keyboard Navigation
- Non-Visual Navigation with a screen reader
- Alternate Visual Access (low vision/colorblind)
- Usability (cognitive/learning disability)
- Non-Audio Access
Step 1: Pre-Test Planning: Web Accessibility Testing Checklist
What portions of the Web Content Accessibility Guidelines (WCAG) apply to your website/application?
Steps 2: Documenting Your Test: Web Accessibility Evaluation Report
How can I record my accessibility findings to share with those who complete the accessibility remediation?
- Build web accessibility testing early in to your development process and ongoing maintainence.
- Become familiar with implementing the standards:
- Testing Web Content for Accessibility - overview of methods in testing
- Manually navigate your pages and forms without a mouse, using only your keyboard. Lose The Mouse Challenge
- Gain the user's perspective on typical design issues. WebAIM
- Test with automated web accessibility toolbars to catch some of the errors. These will typically catch anywhere from 10-30% of the errors, sometimes more. Ensure you get "Errors" down to zero and review alerts as well.
- WebAIM WAVE Browser Extension- Chrome (contrast checking option included) help documentation
- WebAIM WAVE Browser Extension - Firefox
- Siteimprove Accessiblity Checker for Chrome, help documentation
- WebAIM WAVE online checker
- Most automated tools can catch color contrast issues but a manual review of the results is usually needed to confirm no false positives.
- Use different approaches for evaluating websites for accessibility. The World Wide Web Consortium (W3C) Accessibility Evaluation Resources
- Use a disability simulator that helps designers ensure that their content and applications are accessible and usable by the visually impaired. aDesigner is a tool that web authors can use to ensure that the webpages they create are accessible to individuals who are blind or visually impaired. aDesigner disablity simulator
- The Paciello Group offers resources for testing an inclusive design groups. The Paciello Group
- JAWSInspect - This is a fee based checker to simplify testing for screenreader accessibility, without using a screen reader.
- Learn about mobile device accessibility guidelines. Mobile/App Accessibility
Testing web sites and applications using assistive technologies offers you a lot of benefits. You get to learn some of the tools that people with disabilities use to navigate technology, which is incredibly informative. You also get better insight into the true, functional accessibility of the site or application.

Want a demonstration of what IS and is NOT an accessible web page?
Here are websites that show the differences, both in presentation and in structure, between accessible and inaccessible web pages. Use these to practice your website accessibility testing and experiment with different AT devices.
