Positive Peer Culture (PPC) is a milieu driven residential treatment model described in 1985's Positive Peer Culture by Harry Vorrath. His book described his pioneering model as primarily peer driven, with students holding one another accountable. Vorrath posited that this change can happen through “self worth, significance, dignity, and responsibility only as they become committed to positive values of caring and helping of others” (page xi). The key to a Positive Peer Culture model is the training that the staff receive and the common language that is spoken amongst the staff to the students. Many residential settings have pieces of PPC, but a program that is all PPC, lives and breathes the language and the values.
