The Riso-Hudson Enneagram Type Indicator (RHETI® version 2.5)
The Riso-Hudson Enneagram Type Indicator (RHETI® version 2.5) is the world’s most popular Enneagram-based test. It is a scientifically validated, forced-choice personality test with 144 paired statements. The test takes about 40 minutes to complete.
The RHETI® version 2.5 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.
The RHETI® results are available in a PDF format and include your scores for all nine types in a full-spectrum profile, as well as the Expanded Type Descriptions (of over 2,500 words each) for your top three scores. These type descriptions have been revised and updated to provide the most comprehensive type summaries available.
