Web Accessibility and Usability Standards

Note: Section 508, which is what Texas Administrative Code (TAC) §206.70 is based on, will be going through a refresh very soon. The new standards will likely be copied from Web Content Accessibility Guidelines (WCAG) 2.0. Both are shown here to give you an idea of the direction you should be going to meet the future standards.

The links under the WCAG 2.0 Comparison column offer great information on what each standard means and how to comply with that standard using one of the recommended techniques.

Standards as described in TAC §206.70
