Policy Statement

It is the policy of the University that University Websites be accessible, including:

  • New or substantially revised content. All content that is created or undergoes substantial revision after the effective date of this Policy is required to conform to the Accessibility Standard. In addition, Site Owners who manage University Websites that are maintained, upgraded, or updated by vendors are required to ensure that the vendor-provided design, code, and content meet the Accessibility Standard when the contract is entered into or renewed.
  • Existing content. Existing content that does not meet the Accessibility Standard must be brought into compliance over time through a process overseen by the Accessibility Committee. As part of this process, the Accessibility Committee will prioritize important institutional University Websites and those that are most highly trafficked. Site Owners must follow the requirements and deadlines of the Accessibility Committee regarding this process. If the University receives a request by or on behalf of a person with a disability for access to existing content that is not accessible, the University will provide such content in an accessible format unless an exception is approved by the Accessibility Committee (see below).

When meeting the Accessibility Standard is not technically feasible or may require extraordinary measures due to the nature of the information or the purpose of the University Website (i.e., it would create an undue burden by fundamentally altering the nature of the existing content), the Site Owner may, with the agreement of the responsible dean, vice president, department chair, or director (see below), request an exception from the Accessibility Committee. Insufficient funds of a particular unit will not be considered a valid reason for an exception except in extraordinary circumstances. Exception requests may only be approved by the Accessibility Committee.

University Websites must provide a clear link to the Office of Disability Services on all pages and must provide an accessible method for reporting problems accessing the website or any of its content.

Roles and Responsibilities

Deans, vice presidents, department chairs, and directors are responsible for ensuring that University Websites within their areas of responsibility meet the Accessibility Standard.
