The National Longitudinal Study of Adolescent to Adult Health (Add Health) is committed to ensuring accessibility of its website and related tools for our professional and community users. We embrace this value by:

  • Following principles of accessible web design
  • Incorporating accessibility into all phases of the design and implementation process
  • Ensuring usability through ongoing quality assurance mechanisms like expert reviews of the programming and design, user testing, and feedback
  • Staying current with new technology and trends

We will, when possible, exceed federal and industry accessibility standards to assure that tools are truly usable regardless of hearing, visual, motor, or communication ability. Standards for accessibility are defined by Section 508 of the Federal Rehabilitation Act and also by the Web Content Accessibility Guidelines at Conformance Level “Double-A” as outlined by the World Wide Web Consortium’s Web Accessibility Initiative.

Our true measure of accessibility is determined by the end user. We strive to incorporate relevant user feedback into our ongoing updates and welcome suggestions on how we can make improvements for our users.
