So, what’s up? …
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
3
Plan and prioritize
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
4
What are you testing?
•
•
•
•
•
A video gallery?
A site? Is it responsive?
A page?
A mobile app?
Is it for an official review or just a quick check
for potential problems?
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
5
How much time do
you have?
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
6
Prioritize again
• Do you only have to test or are you
responsible for remediating the problems?
• Do you need to tell people how to fix the
problems?
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
7
Use checklists and other resources
• Create or find a checklist for your specific
needs:
– 25 Ways to Make Your Website Accessible (check
for the items listed), by Dennis Lembree
– Accessibility Quick Check, Tom Jewett
– WCAG 2.0 Checklist, WebAIM
– Video and Audio Accessibility Checklist
– Course Accessibility Checklist

After you test …
Think about what tools you like
best—what appeals to me may
not appeal to you.
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13

How about a quick test now?
• Just for a few minutes, let’s see what we
accessibility problems we can find on a
popular site.
• I’m going to use a few tools that I like:
– WAVE Toolbar
– Web Developer Toolbar, by Chris Pederick
– Juicy Studio Accessibility Toolbar
– Paciello Group Web Accessibility Toolbar
– No assistive technologies (?!)

Accessibility remix!

12
Consider another perspective and
approach …
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
13
Consider another perspective and
approach … create an
accessibility team from people
you already have on staff.
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
14
Share the work based on roles
instead of correcting your
colleagues’ work.
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
15
This makes your entire team
responsible and accountable for
their own work.
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
16
Talk with management.
(See Carol Smith’s Negotiate for the User.)

4 keys to building in
accessibility
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
19
Understand disabilities
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
20
Train your colleagues according
to each of their roles.
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
21
Teach them …
• … that we need to test and plan for
accessibility throughout each project's
lifecycle.
• ... how to choose technology that's accessible.
• ... the importance of accessible platforms.
• ... to not just do what the cool kids are doing
for the sake of doing it.
• … development principles (good, clean,
accessible code).
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
22
Teach them …
• ... accessible design principles.
• ... how people who have low-English proficiency,
dyslexia, cognitive impairments, etc. need plain
language and other principles.
• … that we need to conduct usability testing with
people with disabilities.
• … how people with disabilities use their assistive
technologies—and that successfully using one
assistive technology on a project doesn't mean
blanket accessibility.
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
23
Divvy up the standards
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
24
Give them tools.
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
25
The roles overlap.
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
26
Create a policy
• Write an in-house policy (not an accessibility
statement for the public).
– Developing Organizational Policies on Web
Accessibility, W3C-WAI
• Get management support to make it stick.
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
27
It won’t all happen overnight.
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
28
What doesn’t work
•
•
•
•
Putting the work before relationships
Disinterest from upper management
Thinking our process won’t evolve
Allowing the accessibility program to be
personality driven—it must outlive you
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
29
What you’ll gain
• Save money by not making costly
accessibility fixes later.
• You’ll have a solid process that fights the
“accessibility is time consuming and
expensive” issues.
• You’ll have a fluid process—stands
despite staff changes, work demands,
etc.

Now, back to you …

Keep calm and test quickly

Sample process
Tailor this to your needs and to each project.
1. Document this entire process and testing.
2. Choose who should work on the project, and
assign tasks/roles to everyone according to
their skills and strengths.
3. Plan/gather requirements with the decision
makers, stakeholders, designers, developers,
content providers, etc.
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
35
Sample process
4. Determine which standards and guidelines
are appropriate for your project (WCAG 2.0,
Mobile Best Practices, ATAG, CVAA, iOS
Accessibility Standards, etc.).
5. Put accessibility requirements in any vendor
requests for proposals and/or contracts.
6. Determine your users’ top tasks.
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
36
Sample process
7. Review the information architecture.
8. Analyze the resulting wireframes.
9. Conduct usability testing with paper
prototypes (wireframes).
10.Choose and test the color scheme.
11.Assess the design mockups.
12.Review the final written content.
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
37
Sample process
13.Conduct more informal user testing (test the
mockups, content, information architecture).
14.Review the templates (including ARIA);
validate/remediate the (semantic) code.
a. Just because your code validates doesn’t mean
your project is accessible—validate anyway!
b. Just because your site doesn’t validate doesn’t
mean it’s inaccessible—validate anyway!
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
38
Sample process
15.Review the style sheets; validate/remediate
the styles.
16.Test with automated accessibility tools.
17.Review the scripting (JavaScript, AJAX,
jQuery, YUI, whatever); add more ARIA, if
needed.
18.Test again with automated tools.
#QuickA11yTesting | #A11y | @AccessForAll | #AHG13
39
Sample process
19.Test with assistive technologies.
20.Test on mobile devices and e-readers.
21.Test with real people, including several
people with different disability types—don’t
forget to test the written content, too.
22.Continue to improve and test after the
launch (since browsers and software change).
