Web Development Tools


The World Wide Web Consortium (W3C) via the Web Access Initiative (WAI) has published the Web Content Accessibility Guidelines (WCAG) 2.0 Level of Conformance AA which have been adopted by Iowa State to guide web development that is accessible.  Their Quick Reference Guide is useful in helping developers identify guidelines applicable to their projects.

For Rich Internet Applications, the W3C has put forth standards- the Accessible Rich Internet Applications (WAI-ARIA) Recommendation 1.0 - that help inform behaviors, focus, element definition, and other aspects of rich UIs to make them accessible.

If you adopt any of these code examples or tools, or have any established workflow or tools that inform your accessible development, we would like to hear from you.  The Office of Digital Access is working to identify viable tools and workflows for the various platforms and development workflows on campus.  We will appreciate your feedback and collaborate in this effort.
