Voluntary Voting System Guidelines (VVSG)
1. A set of requirements and specifications that are used to test and evaluate the quality of voting systems. Machines are tested to meet the VVSG (Voluntary Voting System Guidelines) as a quality assurance measure. The VVSG tests machines to make sure they meet requirements in a number of categories, including but not limited to functionality, accessibility, and security. HAVA requires that the EAC (Election Assistance Commission) periodically update the VVSG.
