The 21st Century IDEA was signed on December 20, 2018 and impacts the accessibility of federal government agencies' websites and digital services, among other requirements. If you represent an executive agency that creates a new website or digital service intended for public, according to the law, you have 180 days from enactment to ensure that site, application or service is accessible to individuals with disabilities according to Section 508 of the Rehabilitation Act of 1973. Existing websites and digital services must comply within one year of enactment.
