Dear EvalTF,

Although we mostly agree that "Accessibility support must be uniform throughout a single website", there are a few comments in the latest survey [1]. I would like to discuss this a bit more on the list, specifically a bit more about combining evaluations.

In WCAG it is not a problem if you are a person with a disability and you have to use multiple user-agents, assistive technology and other tools and configurations to use a single web page. We do not change this in WCAG-EM: If you want to evaluate using multiple  versions of user agents, tools and screenreaders, that is ok. We only say that this should then be uniform throughout the single website evaluation. For the next single website, you can use another configuration, other tools, assistive technology etc.. This may be depending on the evaluation commissioner, the budget, time etc.

The question is: Can we combine two evaluations by two different evaluators (using different configurations for evaluation) of two different parts of a single website into one accessibility evaluation statement for the single website?

Both results of the evaluators are of course valid. but can they be combined if they use different configurations and are about different parts of a single website?

Kindest regards,
