How much accessibility testing do I really need to do?

Long Story Short

I've created an Accessibility Audit Checklist (http://checklist.garcialo.com)

• Still work in progress (everything can and probably will change)
• WCAG 2.0 Level AA
• Includes coverage for a couple of automated testing tools
• Will hopefully get it on Github soon; the above URL will still work

Overview

First the good stuff, then the boring stuff.

1. Let's look at the checklist
2. Some thoughts on automated accessibility testing
3. How did I put the checklist together?
4. What problems are there with the checklist?
5. Why did I create the checklist?
6. What's next?
