Evaluating Web Page Accessibility

This month is the 25th anniversary of the Americans with Disability Act, which is a federal legislation designed “to [eliminate] discrimination against people with disabilities.” Often times students with disabilities can be left out of online curriculum, which is why it is important to evaluate if your webpage is accessible. In an a recent article George Williams discussed how you can evaluate your webpage for accessibility, he noted the best way to engage in accessibility testing is with actual people. However there are also a number of helpful tools that can automatically check your site for the most important accessibility issues:

  • Wave Toolbar
    WAVE can help you evaluate the accessibility of your web content. WAVE is easy to use, you simply enter the web page address or browse to a file on your computer and select WAVE this page. WAVE will then provide you with a report section at the top of your page with embedded icons and error indicators. RED icons indicate accessibility errors and GREEN icons indicate accessibility features.
  • HTML_CodeSniffer
    HTML_CodeSniffer Is a client-side JavaScript application that checks an HTML document or source code for violations of a defined coding standard. It can be extended by developers to enforce custom coding standards by creating your own “sniffs”. This bookmarklet can work with almost any browser.
  • Tota11y
    Tota11y helps visualize how your site performs with assistive technologies. Testing for accessibility is often tedious and confusing, but tota11y aims to reduce this barrier by helping visualize accessibility violations. Your file will have a small button in the bottom of your corner document, once you click on the button you are able to see the accessibility problems your web page may have.
  • Pa11y
    Allows you to check the accessibility of web pages your own or others. If you are more interested in fixing issues rather than hunting them down you can use pa11y-dashboard.

You can also look at W3C web accessibility evaluation tools list. Over 40 tools listed are software programs or online services that can help determine if the webpage is accessible. All these tools will help evaluate webpage accessibility to ensure everyone can enjoy your webpage.
