An Open Commitment

Our web site is built on the HUBzero® software platform. The HUBzero team is committed to creating websites that are accessible to the widest possible audience, regardless of technology or ability. If you find accessibility problems with our site, please report them so we can take corrective action.

Guidelines, Standards and Testing

Our site has been developed according to the following standards:

Section 508

This website endeavors to meet or exceed the requirements of Section 508 of the Rehabilitation Act.

WCAG 2.0

This website endeavors to conform to level AA standards, and where possible strive for AAA, as defined by W3C's Web Content Accessibility Guidelines (WCAG) 2.0. These guidelines provide web authors and designers with recommendations to help provide website content that is accessible to all users.

Coding Standards

Pages on this site have been authored to be compliant with current W3C standards for HTML (XHTML 1.0 Strict) and CSS. Standards-compliant code helps to ensure that visitors using assistive technologies (such as screen readers) are able to access the site contents.

Additional Testing

In addition to reviewing for compliance with the standards noted above, we periodically test with such technologies as the Web Accessibility Evaluation Tool, AChecker, and try to test with a range of assistive technologies (e.g., JAWS and WindowEyes screen readers). We also appreciate any input from third parties and assistive technology users from the community.

Contributed Content

While we make every effort to make sure that all pages designed and maintained by us are fully accessible, the accessibility of some contributed content is most often beyond our control.
