What Is Section 508

Section 508 is a 1998 amendment to the Rehabilitation Act of 1973 that requires by law that all federal agencies make their electronic content accessible to everyone, including those with disabilities. In order to meet standards, technologies must be determined to be as user-friendly and compatible for disabled users as they are for non-disabled users.


508 compliance not only encompasses the entirety of the federal government but also applies to any company, private or public, that does business with a federal agency or receives funding from them.


Since it was enacted, the amendment has undergone updates of its own to ensure everyone is properly accommodated for. As recently as January 2017 a round of revisions were made to keep up with the continual growth of digitalization. The revisions went into effect in January 2018.


Any company or agency that falls under 508 compliance must make all digital documents, website content, software, emails and apps accessible to people with disabilities. PDFs are not normally accessible by screen readers so they require availability in other forms.


Due to the varying nature of disabilities, flexibility is also heavily emphasized. Electronic data must be available in multiple forms, specific to each disability. Additionally, when government employees have valid requests for accommodation, agencies are encouraged to handle these cases personally rather than applying a universal standard.
