Mapping of WCAG 2.0 to Functional Performance Criteria

The Web Content Accessibility Guidelines (WCAG) success criteria (SC) and the Revised Section 508 Standards share the same objective: to make information and communication technology (ICT) accessible to individuals with disabilities. The revised Section 508 references WCAG 2.0 Level A and AA. The mapping in the table below relates each WCAG SC to the disabilities that may be impacted by non-conformance. In the table, the column headers (columns 2 through 9) represent the disabilities identified by the Section 508 Functional Performance Criteria.

Please note that the information provided in this table is intended solely as informal guidance and is neither a determination of your legal rights or responsibilities, nor a statement of the official views of the U.S. Access Board, the GSA Office of Government-wide Policy IT Accessibility Program, or any other federal agency.
