Announcements and Meetings

ATAG 2.0 is a W3C Proposed Recommendation. This is the last step in the W3C Process before becoming an official W3C Recommendation (standard). (21 July 2015)

ATAG implementation testing now shows 100% of the features meeting the exit criteria. Tools tested include: WYSIWYG editors, CMS tools, app development tools, non-text media tools, social-media tools. (15 June 2015)

ATAG 2.0 has been published with updated Candidate Recommendation exit criteria. This simplifies the exit criteria, reduces the testing burdent and shortens the timelines for completion. (4 June 2015)

ATAG now has implementations of 96% of the success criteria. We are now also working to vet tests and ensure we have two independent evaluations of each implementation. (6 April 2015)

ATAG Test Harness Implementation Scorecard view of testing results to date is fixed. Feature (success criteria) test results are now visible. (24 Feb 2015)

ATAG Tester Training session for testing volunteers. Slide deck from training. (30 January 2015)
