In 2011, the Rorschach Performance Assessment System (R-PAS), a new scoring system for the Rorschach, was introduced. The R-PAS builds on the prior accomplishments of the Exner Comprehensive Scoring system but also corrects some of its limitations. After four decades in use, there was a good deal of data on the Exner system, which permitted careful assessment of the construct validity of the many measures included in this older system. In this way, the variables that had not shown much clinical utility could be removed, creating a more streamlined and rigorously tested scoring system. Moreover, new norms for the scores were introduced based on extensive analysis of several large international datasets. This allows a tester to convert an individual’s scores into percentile ranks based on larger and more diverse samples than were used before.
