This post is a follow-up to our original announcement, on May 30, 2012, about Adaptive Testing.
Beginning July 21, 2012, Everything DiSC assessments will use Adaptive Testing (AT) and a new, more sophisticated scoring algorithm to give participants the most precise DiSC® style assignment possible.
AT is more aligned with contemporary psychological testing—it’s frequently used in aptitude tests, so you may be familiar with the AT assessment method. With AT, respondents are presented with questions and their responses determine the next questions they’re given.
How is the Everything DiSC® AT assessment better than the 79-item assessment?
In addition to thorough beta testing of the Everything DiSC® AT measurement, we hired two independent agencies to perform multiple rounds of analysis focused on construct validity. Two of the most well-respected academic assessments in the psychological community were used to establish construct validity of the Everything DiSC AT assessment: NEO PI-R™ and 16PF®. The agencies also compared the construct validity of the Everything DiSC AT assessment to the Everything DiSC 79-item assessment and the DiSC Classic 28-item assessment.
