It’s relatively easy to find user testers through social media groups, disability and accessibility mailing lists, university accessibility services, or organizations that serve people with disabilities. People with disabilities tend to be receptive to testing when you are improving accessibility, and are often willing to refer you to other potential testers.
It is important that user testers be screened for particular characteristics, including good understanding of web technologies, as well as proficiency using their respective AT. This is necessary, in most cases, to ensure that issues that testers’ experience during testing are attributable to problems with the web content or application being tested, and not the result of inexperience with the Web or limited expertise with the AT being used.
There are a number of questions that you can ask that will help gauge a user tester’s level of knowledge.
The two main categories of questions to cover in screening user testers are:
- Web Knowledge
- Assistive Technology Expertise
