This is the Russian Riso-Hudson Enneagram Type Indicator (RHETI) Version 2.5 in booklet form. It features a newly revised edition of the highly popular questionnaire found in Discovering Your Personality Type along with scoring materials and brief descriptions of the nine types. The type descriptions have also been revised and updated to provide concise information to help in confirming one’s personality type. The RHETI offprint is ideal for workshops, presentations, group settings, or for working with clients.

In this new edition of the RHETI, refinements have been made to about 10% of the questions, thereby increasing the reliability and usefulness of the test as a whole. Version 2.5 is about 70-75% accurate for determining basic type, slightly more accurate than version 2.0. This is also the version that has been independently scientifically validated. Rather than just indicating your basic type, however, the RHETI produces a full personality profile across all nine types. This provides you with a unique portrait, indicating the relative strengths and weaknesses of the nine types within your overall personality.
