There are many things that anyone can do to evaluate the accessibility of a webpage. However, a thorough evaluation requires much more than a quick test with an accessibility tool or two. During this workshop, discover the many steps needed to evaluate something as simple a single checkbox, and learn where you can find resources to help you evaluate your own web content.


A through web accessibility evaluation takes time and expertise. Even the evaluation of something as straightforward as a single checkbox may require several steps across multiple tools. The evaluator may need to check the HTML, CSS, ARIA, and possibly JavaScript during their tests.

During this session, participants will step through the thorough evaluation of a single checkbox as they work to answer several questions, including the following:

-Can the user easily interact with a mouse? A keyboard? Touch? Their voice? -Does the checkbox and text label have enough contrast? -Is any information presented using color alone? -Is all relevant information presented to screen reader users (including the type of form control, a text label, and other important prompts or descriptions)? -What happens if the user changes text size or spacing, or zooms content in the browser? -How about the accessibility of any error feedback?

Participants will be presented with techniques and tools to aid in the evaluation process and will learn where to find resources to aid them in their own evaluation efforts.


  1. A through web accessibility evaluation requires time and expertise.
  2. As demonstrated during the session, the evaluation of even a single element may require dozens of checks.
  3. Tools and resources are available to guide evaluators in their efforts.
