This document is an ICT Accessibility Requirements Statement issued by the Department of Agriculture Forest Service per the Revised Section 508 of the Rehabilitation Act, establishing accessibility standards for software procurement.

The statement establishes technical criteria for NRE FS Software requiring conformance to E207.1 General standards for software components transmitting information or having user interfaces. Software must comply with E207.2 WCAG Conformance standards at Level A and Level AA Success Criteria, with the term "software" substituted for "Web page" or "page" when applying WCAG 2.0 Level A and AA requirements to non-Web software. Non-Web software requiring multiple steps to accomplish activities must conform to WCAG 2.0 as specified in E207.3. Web applications without access to platform accessibility services must conform to Level A and Level AA Success Criteria per E501.1 Scope. Additional technical requirements include software interoperability with assistive technology (E502.1 General); documented accessibility features (502.2); no disruption of accessibility features (502.2.2); and programmable object information including role, state, properties, boundary, name, and description (502.3.1). Software must support programmable modification of object information and values (502.3.2 and 502.3.5), label and hierarchical relationships (502.3.6 and 502.3.7), text content and modification (502.3.8 and 502.3.9), focus cursor tracking and modification (502.3.12 and 502.3.13), event notification (502.3.14), and user preference settings for color, contrast, font type, font size, and focus cursor (503.2). Functional performance criteria require software to provide alternative modes of operation for users without vision, with limited vision, without perception of color, without hearing, with limited hearing, without speech, with limited manipulation, with limited reach and strength, and with limited cognitive, language, and learning abilities.
