  • Functional Accessibility Evaluator (FAE) - The FAE evaluates a web page for its accessibility by referencing the ITAA Web Accessibility Standards which are based on the WCAG 1.0 and Section 508 guidelines. The results of the evaluation are broken into 5 categories: Navigation and Orientation, Text Equivalents, Scripting, Styling and HTML Standards. The judging of the overall performance in each category is a percentage, divided between Pass, Warn and Fail – thus enabling you to focus on the specific areas with most problems. You evaluate a single page or multiple pages.

  • Vischeck - Shows you what your web pages look like to someone who is color blind. You can use Vischeck online with either an image file or running it through your web page, or you can download and use it on your computer.


  • WAVE - Web Accessibility Tool -  The tool reports accessibility violations by annotating a copy of the page that was evaluated and at the same time, providing recommendations on how to repair them. Rather than providing a complex technical report, WAVE shows the original Web page with embedded icons and indicators that reveal the accessibility information within your page.
