 The first version of PASS ("Program Analysis of Service Systems)" was an early 1970 unpublished mimeograph edition aimed to direct money, which was available for new service development in Nebraska, to those proposals most in accord with normalization (Wolfensberger, 1999).The first published edition of PASS, sometimes called "PASS" 2, followed Wolfensberger's move from Nebraska to Canada's National Institute on Mental Retardation (NIMR) and NIMR's publication of Wolfensberger's seminal book, "The Principle of Normalization in Human Services," in 1972.PASS says, in effect, that a program guided by the principle of normalization must consider several important sub-ideas.
