As the Transparent Language Online system updates existing functionality and develops new capabilities, we methodically address the support of accessibility for learners with special needs. Transparent Language Online has not been tested for WCAG 2.0 compliance by third-party experts, although good programming practices and our own on-going internal testing, we are working to support more and more aspects of WCAG 2.0 compliance. Our team is building knowledge of these standards, so that where feasible we can support the broadest possible access to our learning system. Below is a listing of the WCAG 2.0 criteria for software application and web sites with our current assessment of Transparent Language Online status for each criteria.
