disc personality test validity and reliability

If DISC gives us a snapshot of who we are in terms of behavior, our assessment on Core looks at what we value when it comes to behavior and environment. To add on to DISC’s high predictability, we have two other assessments, Core (Individual Values) and Drive (Individual Motivations), that aim to bolster some of the areas that DISC does indeed miss when it comes to understanding people. So if DISC has about an 80–90% validity, what about the part that’s not there? How do we fill that gap? We’ve spent a lot of time in these articles talking about DISC - and I reiterate again just how much we believe in DISC’s power - but we know that DISC alone cannot tell you everything about a person. But the reason DISC isn’t the only assessment we use is because we do see that while it gives you a snapshot of a person’s behavioral profile, it can be so much clearer. We’re not oblivious to that, and that’s why DISC does sit among our three assessment battery: we recognize just how powerful of a tool DISC is. It’s arguably the most widely used assessment globally when it comes to hiring, recruiting, and team-building. Whichever side of the debate you’re on, the fact of the matter is that DISC has been around for almost a century, is used by almost three-fourths of Fortune 500 companies, and is utilized by all branches of the U.S.

I understand seeing both sides, and I welcome the discourse of doubt - and we also hope our results can show you otherwise. But there are also articles like this which aim to serve as a deterrent to the usage of DISC. Scholarly articles are abound (such as this one) that show time and time again that DISC is extremely effective. What does this mean? This high validity means that DISC’s metric of predictability in human behavior is extremely consistent.

Of personality assessments, DISC consistently comes in as one of the most validated assessments, with studies putting its validation at 90%. After all, how are you going to find the right answers when you’re not even asking any questions? By sitting down and asking can I learn more or can I get better with these results? The answer then becomes a resounding YES!īefore I take a jab at DISC, let me start by saying that DISC is one of the three foundational assessments in our assessment battery for a reason. We’ve consistently stressed that it’s not the test alone that will give you all the answers. In tandem, many folks are subject to DISC, Myers Briggs, and a myriad of other tests and while results are being thrown at them, the root of why these tests are being administered are never explained. A lot of folks who haven’t taken assessments roll their eyes at personality assessment tools.
