Voluntary Product Accessibility Template (VPAT)

Last Updated: Nov 17, 2017

The Voluntary Product Accessibility Template (VPAT) is a standardized form developed in partnership by the Information Technology Industry Council (ITI) and the U.S. General Services Administration (GSA) to document a product’s conformance with key regulations of Section 508 of the Rehabilitation Act. The following VPAT document describes how the accessibility features of the VisibleThread product lines help federal agencies address the requirements of Section 508 Standards. The purpose of this is to assist Federal contracting officials and other buyers in making preliminary assessments regarding the availability of commercial “Electronic and Information Technology” products and services with features that support accessibility.
