Accessibility Testing and Technical Solutions

Knowbility provides a wide range of accessible web design and development services to help you get your web site and technology products up to compliance standards. Over the past eighteen years, we have helped literally hundreds of corporations, education institutions, government agencies and nonprofit companies achieve their accessibility goals through testing, training, strategic planning and policy development services.

Our experts are internationally recognized for their role in creating the worldwide standard for web accessibility implementation and training. When we work with you on a project, our goal is to teach-as-we-go. We want your team to incorporate good accessibility practices into your processes and become independent, i.e. able to sustain accessibility into the future.


Knowbility's team of web accessibility professionals is, arguably, the most knowledgeable in the field. They do testing right. They maintain the highest standards and will make sure you know how to make your site truly accessible.

Accessibility Testing and Auditing

Knowbility performs Expert Manual testing to show you what the accessibility barriers are on your site or app and how to remove them. First, we do a preliminary review of your site to determine sample screens to test. Sample screens will have elements that should be made accessible wherever they occur throughout the site. Choosing sample screens eliminates redundancy in testing and reporting and reduces cost. If you have areas of your site that you're particularly concerned about, let us know and we'll be happy to include them in our testing.

After we’ve chosen sample screens, one of our accessibility expert looks at each of them and reports the accessibility barriers/errors according to WCAG 2.0 AA and Section 508 standards. Our experts are often assisted by native screen reader users to help parse problematic issues and determine best approaches for accessibility and usability.

Report Documentation

Test results are presented in a two-part report showing the sample screens with Pass/Fail status for WCAG 2.0 AA compliance checkpoints, along with an Issues Summary document with discussion of the accessibility errors, what each means and how to fix it (to the code level when necessary). After we deliver the accessibility report, we do a Q&A type conference call to explain the issues and fixes so your team is confident and comfortable implementing those technical solutions.


After your team has followed our report recommendations we are happy to go back and re-rest the sample pages (at ½ the testing rate) to make sure there are no remaining accessibility errors/barriers, i.e. you did the fixes right.


If, after re-testing, all of the accessibility issues discovered during the first test have been remediated properly, that is there are no accessibility barriers on those sample screens, we will issue a letter of validation stating that fact. These letters of validation have been used many times in structured settlements and are perfectly sufficient for legal purposes
