If you’ve used Behavior Style assessments before, there’s something new you’ll want to see.

We’re rolling out updated versions based on the new Behavior Style model we recently introduced—while still keeping the classic version available.

This short video gives you a quick overview of what’s changing.

Take a look...

Over 40 years ago, we introduced our Behavior Style model to help people better understand patterns of behavior.

Since then, the model has evolved—but the core idea has remained the same: Behavior Styles are about how people behave, not who they are.

Today, we’re introducing one of the most meaningful updates we’ve made to that model.

These changes make the model clearer, more intuitive, and easier to apply—especially for people encountering it for the first time.

In this video, we will walk you through what’s new and why we made these changes.

We're interested to hear what stands out to you after you’ve seen it.
