Accessibility Principles

The W3C has specified three levels of accessibility in the WCAG Standards: Levels A, AA, and AAA. Most legal requirements specify compliance with Level AA of the WCAG guidelines. Since that is so, this document won't attempt to provide a listing of all Level AAA requirements. Also, keep in mind that some of the Level AA requirements aren't especially relevant to Process Director either, so we will concentrate on the Level AA requirements that are most relevant. Finally, remember that some requirements simply aren't related to the controls or other features of Process Director, but must be implemented manually, such as giving logical names to form controls, or to the link text you use for hyperlinks. Process Director will automatically implement accessibility standards where it can, but much of the burden remains upon you, as a form designer, to implement accessibility standards as part of your design.

So, with the above in mind, let's take a look at the WCAG standards, and see if we can't provide some helpful guidance.

The WCAG standards are defined by four principles, with guidelines for each principle that specifies how it should be implemented in a web application. The guidelines for each principle are linked below.

Principle 1 - Perceivable: This principle relates to making information and user interface components presentable to users in ways they can perceive.

Principle 2 - Operable: This principle relates to how user interface components and navigation operate.

Principle 3 - Understandable: This principle relates to making information and the operation of the user interface understandable to users.

Principle 4 - Robust: This principle relates to making content robust enough to be interpreted by a wide variety of user agents, including assistive technologies.
