WCAG 2.0 guidelines are categorized into three levels of conformance in order to meet the needs of different groups and different situations.
Level A sets a minimum level of accessibility and does not achieve broad accessibility for many situations. For this reason, UC recommends AA conformance for all Web-based information.
