The overall goal of the Illinois workNet Portal is to create web content that meets the needs of all users and is accessible to the broadest possible range of users by being compatible with a wide range of assistive technologies. In an effort to address these needs, the standards to which web content is developed in the Illinois workNet Portal are based on the Amendment to the Workforce Rehabilitation Act: Federal "Section 508," the World Wide Web Consortium (W3C), and the Illinois Information Technology Accessibility Act.
For accessibility testing, we recommend a variety of tools including:
Accessibility Checklist 
The following tests can be used to check accessibility during development. Final testing will still need to be performed by experienced testers using assistive technologies, but these techniques will help catch and correct most accessibility errors early in the development process.
The Functional Accessibility Evaluator (FAE) 
is an easy to use tool. Simply type or paste in your URL and click Evaluate. The Firefox Accessibility Extension allows the FAE to run on dynamically generated pages. Note: Firefox is required to use this add-in. Download Firefox 3.0 online.
Instant Eyedropper allows you to determine the web color code for any pixel on your screen. This tool is used in conjunction with other programs that check color contrast accessibility.
Snook’s Luminosity Contrast Checker checks color accessibility.
Juicy Studio’s Luminosity Contrast Checker checks color accessibility.
