Accessibility

We believe this site has Level AA Conformance inline with the W3C Web Content Accessibility Guidelines 1.0, including all Priority 2 checkpoints defined in the Guidelines. The Web Content Accessibility Guidelines 1.0 explain how to make Web content accessible to people with disabilities. Conformance to these Guidelines will help make the Web more accessible to users with disabilities and will benefit all users.

Please note that use of this logo is not conditional on an automated test. There is as yet no tool that can perform a completely automatic assessment on the checkpoints in the guidelines, and fully automatic testing may remain difficult or impossible. For instance, some checkpoints rely on an interpretation of what "important" information is, or whether the text equivalent for a non-text element is accurate.

It is also possible for automated accessibility checkers to register "false negatives" or "false positives" due to the type of mark-up on a page. For these reasons, the logos on this page are used to indicate only a claim of conformance made by the author of a page, not a machine-validated conformance.
