This is one of the problem of WCAG 2.0 that we have also noticed in italian
government working group for accessibility. The definition of accessibility
supported regarding different assistive technologies in a real big problem,
especially if the conformance declaration isn't a voluntary declaration but
a law requirement.
I think that evalutation could be do by different people but with the same
"baseline" (same technologies for testing), otherwise I think is required
that any evalutator must evalutate the same pages for conformance.

Oggetto: Combining evaluations

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

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,
