In 1974, John Exner published the Comprehensive Scoring System for the Rorschach, in which he reworked earlier scoring systems into a comprehensive and systematic approach. He also provided considerable empirical research for his results, showing perfectly respectable reliability and validity. His system has been revised and updated multiple times. While there are still criticisms leveled at Exner’s approach, many of them legitimate, he has undeniably provided a scientifically supported system with which to score the Rorschach.
