36 CFR Part 1194 - Proposed Information and Communication Technology (ICT) Standards and Guidelines NPRM - Preamble

A. Proposed 508 Standards

The proposed standards replace the current product-based approach with a functionality-based approach. The proposed technical requirements, which are organized along the lines of ICT functionality, provide standards to ensure that covered hardware, software, electronic content, and support documentation and services are accessible to people with disabilities. In addition, the proposed standards include functional performance criteria, which are outcome-based provisions for cases in which the proposed technical requirements do not address one or more features of ICT.

The four major changes in the proposed 508 Standards are:

• Broad application of WCAG 2.0: The proposed rule would incorporate by reference the Web Content Accessibility Guidelines (WCAG) 2.0, a voluntary consensus standard developed by ICT industry representatives and other experts. It would also make WCAG 2.0 Success Criteria applicable not only to content on the “World Wide Web” (hereafter, Web), but also to non-Web electronic documents and software (e.g., word processing documents, portable document format files, and project management software). By applying a single set of requirements to websites, electronic documents, and software, this proposed provision would adapt the 508 Standards to reflect the newer multifunction technologies (e.g., smartphones that have telecommunications functions, video cameras, and computer-like data processing capabilities) and address the accessibility challenges that these technologies pose for individuals with disabilities.

• Delineation of covered electronic “content”: The proposed rule would also specify that all types of public facing content, as well as eight enumerated categories of non-public facing content that communicate agency official business, would have to be accessible, with “content” encompassing all forms of electronic information and data. The existing standards require federal agencies to make electronic information and data accessible, but do not delineate clearly the scope of covered information and data; as a result, document accessibility has been inconsistent across federal agencies. By focusing on public facing content and certain types of agency official communications that are not public facing, the proposed rule would bring needed clarity to the scope of electronic content covered by the 508 Standards and, thereby, help federal agencies make electronic content accessible more consistently.

• Expanded interoperability requirements: The existing standards require ICT to be compatible with assistive technology – that is, hardware or software that increases or maintains functional capabilities of individuals with disabilities (e.g., screen magnifiers or refreshable braille displays). But, because this requirement has given rise to ambiguity in application, the proposed rule would provide more specificity about how operating systems, software development toolkits, and software applications should interact with assistive technology. These proposed requirements would allow assistive technology users to take full advantage of the functionalities that ICT products provide.

• Requirement for RTT functionality: The proposed standards would require real-time text (RTT) functionality wherever an ICT product provides real-time, two-way voice communication. RTT is defined in the proposed rule as text that is transmitted character by character as it is being typed. An RTT recipient can read a message while it is being written, without waiting for the message to be completed; this is different from other message technologies such as “short messaging service”, or SMS, which transmit the entire message only after typing is complete. This proposed requirement would have an impact on federal agencies as well as ICT providers, federal employees, and members of the public.
