Social role valorization (SRV) is a method for improving the lives of people who are of low status in society. (In countries of the British commonwealth, the third word in the term is usually spelled valorisation, but the abbreviation is the same.) SRV was formulated in 1983 by Wolf Wolfensberger. He developed SRV as his successor to the earlier Principle of Normalization In Human Services, which originated in Scandinavia in the early 1960s (Nirje, 1969) and which he then promulgated throughout North America, as well as in England, France, and Australasia.
