Testing methodology is determined by the unit webmaster and site owners. The techniques described here are not exhaustive, but should help you to understand key accessibility issues that may affect your site.Recommended testing issues include:

  • ALT text: alternate text for images and other non-text elements
  • HTML heading structure: properly nested H1-H6 elements, describing the outline of a page
  • Keyboard accessibility testing: all content and interactivity are available via keyboard-only input
  • Forms labeling: label or title elements for all interactive form fields
  • Color contrast: sufficient color contrast for low-vision and color-blind users
  • Tables testing: proper table structure and relationships between table components

An automated site assessment, using the Functional Accessibility Evaluator or a similar tool, can also expose opportunities to improve accessibility prior to a University-sponsored assessment.

A variety of tools and techniques exist to help you assess the accessibility of your site, and to remediate, correct and adjust where necessary. Remember, accessibility is more like gardening than like construction--it is a continual process with the goal of moving ever closer to a product that can be used effectively by all.
