Accessibility at NSF

The U.S. National Science Foundation is committed to making its websites accessible to individuals with disabilities by meeting or exceeding the requirements of Section 508 of the "Rehabilitation Act."

What is Section 508?

Section 508 is a federal law that requires agencies to provide individuals with disabilities equal access to and use of electronic information and communications technology comparable to those who do not have disabilities, unless an undue burden would be imposed on the agency.

Section 508 applies to all electronic content, including documents, webpages, presentations, data, social media content, blogs, certain emails, systems and IT tools.

You can learn about Section 508 and its technical standards at

Our commitment

NSF's accessibility specialists work to ensure that NSF websites are, to the maximum extent feasible, accessible to individuals with disabilities. We aim to comply with the World Wide Web Consortium Web Content Accessibility Guidelines (WCAG 2.1 A/AA).

You should be able to do the following on NSF websites:

  • Use a screen reader to read the content of a webpage by using the tab, space and arrow keys on your desktop, laptop or mobile device keyboard.
  • Easily distinguish pieces of information on a webpage through seeing or hearing.
  • Access all information through HTML or an alternative, accessible format (such as a DOC, XLS or 508-compliant PDF file).
