This paper discusses Model Coherency one of fifty dimensions of human service quality measured by PASS 3 (Wolfensberger and Glenn, 1975). It is written mostly for people who are learning about PASS 3 in an introductory training workshop. The only effective way to learn about Model Coherency – like the rest of PASS 3 – is continuing practice in analysis of human services; reading this will help, but it won’t substitute for guided practice with your team.
