Re: WCAG 3.0 public comment - 5.3 Overall Scores

Hello Alistair,



From my perspective, it was selected as a starting point based on initial tests with the assumption that it would change as we gathered more data and had broader and more in depth discussions (see the editor's note for Overall Scores<https://www.w3.org/TR/wcag-3.0/#overall-scores>).



We plan on discussing conformance and scoring in much more depth in the upcoming meetings and whether to keep this approach or move to something else is part of that conversation. If we decide to keep this approach, then the cutoff point would need to be determined based on testing and by consensus agreement.



Kind regards,



Rachael

    Hi,



    Please excuse my use of this email address - I’m in the process of getting a GitHub login, but just wanted to send some quick feedback as I read the document.



    Reading 5.3 Overall Scores in W3C Accessibility Guidelines (WCAG) 3.0, W3C Editor's Draft 03 August 2021. It states "Conformance at the bronze level requires no critical errors and at least 3.5 total score and at least a 3.5 score within each functional category."



    Seeing as a score of 2 is described as Fair, 3 is defined as Good, and a score of 4 is defined as Excellent.  Why was a score of 3.5 settled on?



    My comment is that 3.5 feels arbitrarily high, and a little odd given it does not equate to a named level.  It is almost so high that it’s not worth mentioning the Fair, or Good as being in any way worthwhile targets (although I do understand the average system).



    I wonder if there will be a perception issue with regard telling the user to immediately go further than Good.



    The question will undoubtedly be asked by some - isn’t “Good" good enough, and if not - why isn’t “Good" good enough?   The likely needs to be a very clear explanation of how / why 3.5 is a good choice.



    This may well have been covered intensely already, so apologies in advance.  Just thought I’d send the comment along.



    Very best regards



    Alistair
