Description of the WAVE accessibility evaluation tool

WAVE - http://wave.webaim.org/ - is tool that helps web developers evaluate the accessibility of their content. WAVE uncovers underlying page information related to accessibiity, allowing it to be evaluated in context. WAVE checks for compliance with standard guidelines, as well as issues not identified in the guidelines. The absence of errors DOES NOT mean that a page is accessible; only a human being can determine that. WAVE is provided by WebAIM, an organization within the Center for Persons with Disabilities at Utah State University.


  1. Errors, Features, and Alerts - RED icons indicate accessibility errors. GREEN icons indicate accessibility features. You can view a brief overview of what each icon or indicator means by mousing over it. To get a more in-depth description select the Icons Key tab at the top of the page.
  2. Structure/Order - Number indicators show the reading/navigation order of the page. Follow the numbers to determine if the order makes sense and is logical.
  3. Text-only View - Only the underlying text of the page, including alternative text for images. Visual styling is removed. Shows what a screen reader would likely read.
  4. Outline View - Shows only the headers within your page. The structure should be logical and appropriate.
