The document describes the C.H.A.N.G.E. program, which aims to increase HIV testing among people who don't know their status. It does this by training volunteers as "envoys" to encourage testing among their friends, family and social networks. Envoy volunteers receive coaching on confidentiality and discussing HIV testing. Their role is to help at least 10 people in their networks learn their HIV status through testing. The program offers incentives for envoys and those who get tested. It is run through the Compass organization to promote HIV education and awareness.
