(The content of the page was last updated by Giorgio Brajnik on 2011)
The purpose of this method is to fill a gap concerning evaluation of web accessibility. In fact, the most often used method is the standards review (or conformance testing) coupled with WCAG 1.0/2.0 guidelines or Section 508 requirements (or other similar principles). On the other side there are methods that are used less often, like user testing. Both methods can be used for assessing accessibility levels, but there are shortcomings in both cases.
