One of the key concepts of WCAG 2.0 is testability. This is about ensuring that each success criterion can be tested either by a machine, or manually in such a way that at least 80% of the human testers would agree whether it is a success or a failure.
Testability Costing Too Much?

As I was unable to attend @Media this year, I still haven’t had the opportunity to meet Joe Clark ‘in the flesh’. However, I did hear from his blog that he’s retiring from web accessibility. He has other things to work on.
Well, I didn’t hear it from his blog straight away. Firstly I had to [...]

As many of you will already know, I’ve had a number of erm… disagreements with Mike Davies of Isolani. These have mostly come about because we fit into different ‘accessibility camps’: I believe accessibility shouldn’t stop at “enabling access to people with disabilities” but should also encompass cross-browser and cross-platform support where possible. Mike disagrees. [...]

What does WCAG 2.0 mean, then really, I mean when you really get down to it? Well, as it has morphed into a much more usable set of documentation, it’s much more likely that it will make it through to being a formal Recommendation, there is now more of a need to understand what it’s [...]

As the more astute of you will have noticed, I have already commented on the latest draft of WCAG 2.0 having written a review of WCAG 2.0 for Accessites just over a week ago. Why not pop over there to read it if you haven’t already?
If you can’t be bothered to read the review in [...]

I noted earlier today that Mike Davies from Isolani has picked up on a piece I wrote in October last year called Be Accessible, Don’t Meet Guidelines, in which I tried to argue that WCAG was not infallible, and that it was more important to recognise the real-world accessibility needs of website users than it [...]

A few days ago I pointed out that Crippled Monkey (of BBC Ouch! fame) was promoting Blogging Against Disablism Day 2007. While I may be late, at least according to my time zone I’ve got a few hours left to spare.
I plan to keep this as simple as possible, so here goes:

How do I define [...]

I noticed there is apparently a Blogging Against Disablism day on the 1st of May.
What are you doing on May Day? Let’s face it, dancing round a tall pole on the first day of May isn’t exactly the most accessible activity for most disabled people, so instead Crippled Monkey would respectfully suggest that you take [...]

Ah yes, the ongoing saga of whether or not WCAG 2.0 should include validity in there somewhere.
Well, according to the lastest minutes of the Working Group, they have finally got around to looking at it, and they have decided to refer the issue back to Committee.
They had previously dropped validity from their criteria, simply instead [...]

After offering my own thoughts on the Better Connected 2007 thing, where I mentioned some of the problems in trying to assess accessibility, particularly when it comes to measuring it across different websites. I’ve since volunteered to give someone else’s site a good going-over and do an accessibility audit for them — and provide them [...]
