Think we're just another testing tool vendor? Not quite. At Tenon, we're committed to ensuring your web accessibility efforts are successful. That includes supporting you as you add Tenon into your design, development, QA, content, and compliance efforts.

Accessibility Testing, Consulting, Training, and Development


Effective accessibility testing involves more than just finding problems, but offering direct and clear guidance on how to fix the problems found. Our testing methodology is rigorous, accurate, and thorough, offering unprecedented efficiency. Our goal isn't just to find accessibility problems, but to assist you in bringing your system in compliance as quickly as possible.


If you sell ICT products and services such as software, hardware, or web-based products to the Federal Government, chances are they're going to ask you for a VPAT. It is also often the case that State Governments and, increasingly, higher education customers will ask for one. The VPAT is a document in which you disclose the state of your product's compliance with the technical provisions of Section 508.

Creating a VPAT requires a thorough review of your product by a skilled reviewer who understands both your product and Section 508 & WCAG. Generally it isn't a good idea to write your own VPAT unless you have skilled accessibility SMEs in house.

We have done dozens of VPATs over the years and, after thorough review, can ensure that your VPAT deliverable is clear, accurate, and honest.


Tenon's founder, Karl Groves, has trained hundreds of developers, designers, QA staff, and project managers on accessibility in 5 different countries on 3 different continents. No single person delivering accessibility training has the depth and breadth of experience in web development and accessibility as Karl Groves.

We offer training on design, development, and testing. Training can be delivered in-person or online and we also offer pre-built video training modules that are SCORM-compliant.


Effectively ensuring you're successful in accessibility requires more than just auditing and remediation. It requires new approaches, policies, procedures, and practices.

We have the experience necessary to assist customers handle high-risk situations like lawsuits, demand letters, and OCR complaints. We have experience helping to guide our customers in adding accessibility to policy, program/ project management, and procurement.


All of Tenon's Web Development staff have at least 10 years experience in development. We have the knowledge necessary to both develop and remediate modern web systems to ensure they're accessible.

One of the biggest differences between Tenon and other accessibility consulting firms is that every single person involved in testing and consulting also writes code every single day. This means we can also write the code for your product, ensuring it is accessible.
