 Starting in the early 1980s, Dr. Wolfensberger's teaching of normalization also shifted to Social Role Valorization, which led to a new service evaluation tool called PASSING (Wolfensberger & Thomas, 1983, 2007).In PASSING, there is no Model Coherency rating, but most of the constituent parts of model coherency are assessed by separate ratings.So, as PASSING began to be disseminated, PASS itself fell rapidly by the wayside, and the teaching and learning of model coherency also greatly diminished.
