Biomedical Citizen Science Hub Accessibility Statement

The Biomedical Citizen Science Hub strives to serve all users including those with disabilities by way of guidance and best practices as well as specific disability support. While we make every effort to make sure that all pages designed and maintained by us are fully accessible, the accessibility of community contributed content is beyond our control. Members are encouraged to make content contributions to serve all including those with disabilities.  Resources are available to make contributions accessible. Biomedical Citizen Science Hub staff are available to answer questions and can be reached by submitting a support ticket, via a web form at contact us or directly via email at


HUBzero Accessibility - An Open Commitment

Biomedical Citizen Science Hub is powered by HUBzero®, a Purdue open-source project.  HUBzero® is committed to providing a website that is accessible to the widest possible audience, regardless of technology or ability. HUBzero is actively working to increase the accessibility and usability of our website and in doing so adhere to many of the available standards and guidelines. 


Guidelines, Standards and Testing

HUBzero® has been developed using the following:

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 ToolAChecker, 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.


Understanding Section 508

In 1998, Congress amended Section 508 of the Rehabilitation Act of 1973 to require that federal agencies make their electronic and information technology accessible to people with disabilities. Specifically, Section 508 requires that when federal agencies develop, procure, maintain, or use electronic and information technology, federal employees with disabilities and individuals with disabilities, who are members of the public seeking information or services from a federal agency, have access to and use of information and data that is comparable to that provided to individuals who do not have disabilities.

The legal requirements of Section 508 of the Rehabilitation Act of 1973 are defined by a series of laws, regulations, and standards as a result of the amendments instituted in 1998. In addition, the World Wide Web Consortium (W3C) works with organizations around the world to evolve strategies, guidelines, resources, recommendations, and ultimately new, improved standards to help make the Web more accessible to people with disabilities. The resulting W3C recommendations for standards may eventually become part of a revised set of standards for Section 508 law. provides information on the standards, regulations and laws pertaining to Section 508. The Web Accessibility Initiative is a body of the World Wide Web Consortium (W3C) dedicated to discussing and setting standards for Web accessibility.
