How often are WCAG standards updated to remain relevant?

The correct choice regarding how often WCAG standards are updated is that they are typically revised every two years. This two-year cycle allows for the standards to be reviewed and updated based on feedback from the accessibility community, advancements in technology, and changing web practices. By doing this, WCAG can ensure that the guidelines remain relevant and effective for promoting accessibility on the web.

Regular updates are crucial because the digital landscape evolves rapidly, and new challenges arise in making online content accessible to individuals with disabilities. By adhering to this biannual schedule, WCAG can incorporate the latest insights and innovations in accessibility, thereby enhancing the overall user experience for everyone.

This iterative approach also aims to balance the need for stability in widely recognized standards with the necessity of keeping pace with new developments, which ultimately benefits web developers and users alike.
