The Help America Vote Act (HAVA) of 2002 (Public Law 107-252) was signed into law by President Bush on October 29, 2002. Section 231 of HAVA requires the Director of NIST to provide for the accreditation of laboratories that conduct testing on the hardware and software of voting systems. In response to the HAVA, the National Voluntary Laboratory Accreditation Program (NVLAP) has established a program for laboratories that test voting systems.
