In the beginning of the Six Sigma movement, the martial arts belt system was adopted as a way to show knowledge and progression through the methodology. The belt colors that became most popularized are:
- White Belt – Overview of tools and methods
- Yellow Belt – White Belt + Most common improvement tools
- Green Belt – Yellow Belt + statistical analysis (with software) and advanced quality methods
- Black Belt – Green Belt + advanced statistical analysis, improvement deployment and mentoring Green Belts
- Master Black Belt – Black Belt + numerous Black Belt projects, large complex projects, and mentoring Black Belts and Executives
Our Green Belt program includes all White and Yellow Belt training content.
WHITE BELT
Before deciding to pursue a certification program, you might consider starting at the White Belt level.
We do not offer a White Belt certification, only a White Belt training certificate. We don’t offer certifications unless there is some application of the learning to a real-life project.

We are currently finalizing our Yellow Belt program. We are testing it out with a group of nonprofits in early 2026. Contact us if you are interested in offering a Yellow Belt training to your organization.
