The Voluntary Product Accessibility Template (VPAT) is a document which evaluates how accessible a particular product is according to the Section 508 Standards. It is a self-disclosing document produced by the vendor which details each aspect of the Section 508 requirements and how the product supports each criteria.

Creating this document ensures easier adoption by organizations and agencies which require software to comply the United States' Rehabilitation Act of 1973 aka section 508 compliance.
