When an online course is accessible, it means that all students, including those with disabilities are able to access course content. If there are any online components that are impossible to make accessible, there should be an equivalent alternative so that students with disabilities are not denied access to course content.
A course provider initially develops or adapts an existing online course so it is accessible to all students. The TXVSN Accessibility Guidelines document helps course providers break requirements down to achievable objectives, but a course provider may need to provide training for its course developers in the requirements of Section 508 of the Rehabilitation Act of 1973, Web Content Accessibility Guidelines (WCAG), and other accessibility standards. TXVSN provides training with the free online course On Target for Accessibility.
