What's the Best Enneagram Test?
RHETI - 27% accurate. (Since this is the upgraded version, I wonder how inaccurate was the RETI that I took? That one scored me as a type 3. I LOL'd at the inaccuracy of the result when I read up on the type 3 to see if it fit me.)
WEPSS - 33% accurate. (From the website: "The WEPSS is a standardized, reliable, and valid Enneagram inventory, the only one published by a major psychological test company and reviewed in Buros's Mental Measurements Yearbook, a respected authority in the testing field." No wonder they charge you to take it!
SEDIG - 58% accurate. This is a one-question-per-type inventory, but the "questions" are basically one paragraph essays. I found a copy of it here:
Probability that true type is among top 3 scores for the three tests listed above:
RHETI - 63%
WEPSS - 93%
SEDIG - 83%
