Below are some great resources for learning about the accessibility laws and standards we should abide by. Of these laws and standards, ASCIT recommends WCAG 2.0 level A and AA conformance but encourages WCAG 2.1 level A and AA conformance. Section 508 of the Rehabilitation Act of 1973 was recently updated to harmonize with WCAG 2.0 A and AA, so conforming to either WCAG standard will significantly decrease your chances of violating accessibility laws.
The official government website for Section 508 offers a rundown of the regulations and policies that have resulted from the law. There are also numerous other resources, including tools for implementing the policies, websites and resources for evaluating compliance, online training, examples of similar State legislation, and more.
