1592 <http://trace.wisc.edu/bugzilla_wcag/show_bug.cgi?id=1592> RNID Comment on Conformance Validity Long post with Summarized with the following exerpts Therefore, I do not believe the following statement is correct: "When multiple people who understand WCAG 2.0 test the same content using the same success criteria, the same results should be obtained." This problem that the success criteria which should offer objectively "testable" conditions often fall short of that definition is acknowledged in other parts of the document or in editorial comments, where it states for example that "The use of "clearly" and "concisely" makes this untestable". In terms of credibility, it would be better if the guidelines would simply admit the subjective nature of certain criteria. CLOSE buy changing "When multiple people who understand WCAG 2.0 test the same content using the same success criteria, the same results should be obtained." To "When multiple people who understand WCAG 2.0 test the same content using the same success criteria, the same results should be obtained (with .8 inter-rater reliability or better)." THEN CLOSE with - the language cited has been removed from the guidelines and many success criteria that were not testable have been moved to advisory techniques. The sentence "When multiple people who understand WCAG 2.0 test the same content using the same success criteria, the same results should be obtained." was changed to "When multiple people who understand WCAG 2.0 test the same content using the same success criteria, the same results should be obtained (with .8 inter-rater reliability or better)."
