The results of these checker tools are provided for informational use only, and are based on an automated assessment and in some cases on user testing of the web page to rate its accessibility for users with disabilities. When it is based purely on automatic testing it covers only a subset of the possible tests derived from WCAG 2.0 - the remaining ones would need assessment by human experts. In addition web page compliance with such accessibility guidelines doesn't necessarily guarantee a successful experience for each web site visitor.
