Accessibility

Websites built with accessibility in mind are flexible in meeting different user needs, preferences and situations. Though these methods can increase usability for everyone who uses the web they are often legally required to be implemented in a specific effort to prevent discrimination against people with disabilities.

See the tracker under Accessibility Compliance in Moodle 1.8 and Compliance with Italian Legislation on Accessibility for more information on what we are doing for Moodle 1.8.
