WCAG 2.1 Implementation Report

This is the implementation report for Web Content Accessibility Guidelines (WCAG) 2.1. This report was prepared during the Candidate Recommendation of the guidelines, when implementability was tested by finding sites that meet the requirements, and evaluating to ensure they conform. Some sites were used to demonstrate implementation of specific success criteria only, while others were used to demonstrate implementation of full conformance at levels AA and AAA. Much more substantial testing was described in the WCAG 2.0 Implementation Report; only new and changed features were tested for WCAG 2.1. This implementation report demonstrates how the Candidate Recommendation Exit Criteria were met.

Success Criteria

The following table lists the new success criterion in WCAG 2.1. The data is taken from the set of sites that were chosen to be included in this report. "Implementations" is the number of sites that actively implemented the success criterion. Each number links to a page providing the data behind that number. Only documentation that there are at least two active implementations of each success criterion is required to exit Candidate Recommendation.

Success Criterion Level Implementations
1.3.4: Identify Common Purpose AA 10
1.3.5: identify Purpose AAA 5
1.4.10: Reflow AA 13
1.4.11: Non-Text Contrast AA 14
1.4.12: Text Spacing AA 13
1.4.13: Content on Hover or Focus AA 7
2.2.6: Timeouts AAA 2
2.2.7: Animation from Interactions AAA 2
2.4.11: Character Key Shortcuts A 5
2.4.12: Label in Name A 15
2.5.1: Pointer Gestures A 6
2.5.2: Pointer Cancellation A 11
2.5.3: Target Size AAA 4
2.5.4: Concurrent Input Mechanisms AAA 5
2.6.1: Motion Actuation A 4
2.6.2: Orientation AA 11
3.2.6: Status Changes AA 5

Conformance Levels

The following table lists information about the three conformance levels in WCAG 2.1: A, AA, and AAA. To meet a given conformance level, a site must satisfy all the success criteria at that level. A success criterion is satisfied by being actively implemented with sufficient techniques, or by virtue of being not applicable to the content of the site. The converse is also true, that there must be no failures of the success criterion requirements on the site.

To exit Candidate Recommendation, there must be documentation of eight implementations that conform to AA, and two that conform to AAA. Because AA sites also meet level A, separate documentation for that conformance level was not collected.

Conformance Level Sites that meet level
AA 7
AAA 3
