How accurate is the Birkman assessment?
Moreover, how accurate is the DISC assessment?
Validity studies of our DISC show that 75% of the people say our report is 95% to 100% accurate. 90% say they are 90% to 100% accurate. Very rarely do we hear people say our DISC report is less than 80% accurate. If people don't say it's at least 90% accurate, it may be time to change assessments.
Likewise, are there any accurate personality tests?
Personality assessments are valid and reliable. Personality tests are sold on the promise that they are valid (they measure what they say they will measure) and reliable (they produce consistent results). “Many studies over the years have proven the validity of the MBTI instrument,” says the Myers & Briggs Foundation .
The closer to one, the more accurate the predictive power of the assessment. A robust assessment tool, such as the Hogan Assessment suite (HPI, HDS, and MVPI) has a predictive validity of . 54.
