Students with diverse cognitive, linguistic, and academic abilities benefit from accessible text. The Web Content Accessibility Guidelines (WCAG) establish numerous requirements (known as success criteria) to ensure that text is perceivable, operable, and understandable to all users. This guide discusses the essential criteria related to text accessibility. Following these guidelines when creating course content, such as documents, slides, and pages in a learning management system (LMS), will help you eliminate potential barriers for your learners.
