ATutor WCAG 2.0 Implementation

This document outlines ATutor's compliance with the W3C WCAG 2.0 recommendations.

ATutor is a Learning Content Management System used to design and deliver online courses. It is still possible for content authors to create inaccessible content should they choose to ignore recommendations made by the built-in accessibility checker, though ATutor will conform with the AA level, as well as most of the AAA level recommendations.

NA = Not applicable
NI = Not Implemented
**(NI) = Needs Implementing
? = Unsure if conformance is met (e.g. Colour contrast)
C = Conforms
