Level A and Level AA Success Criteria and Conformance Requirements in WCAG 2.0 – Web Content
Accessibility Guidelines, W3C Recommendation, December 11, 2008, IBR approved for: Appendix A (Section 508
of the Rehabilitation Act: Application and Scoping Requirements)

Evaluation Method
The evaluation was performed through manual testing, following official documentation of the Section 508 standards andthe WCAG 2.0 conformance requirements, and by using accessibility testing toolkits such as Axe by Deque Systems(https://www.deque.com/axe/) and ANDI by the Accessible Solutions Branch of the Social Security Administration(https://www.ssa.gov/accessibility/andi/).
Evaluation Terms
The terms used in the Conformance Level information are defined as follows:•

Supports – The functionality of the product has at least one method that meets the criterion without known
defects or meets with equivalent facilitation.

•

Partially Supports – Some functionality of the product does not meet the criterion.

•

Does Not Support – The majority of product functionality does not meet the criterion.

•

Not Applicable – The criterion is not relevant to the product.

•

Not Evaluated – The product has not been evaluated against the criterion. This can be used only in WCAG 2.0
Level AAA.

Note: When reporting on conformance with the WCAG 2.0 Success Criteria, the application was, in part, evaluated basedon the following conformance requirement: the presence of full pages, complete processes, and accessibility-supported
methods of use, as documented in the above-referenced WCAG 2.0 Conformance Requirements.
