Six Sigma Green Belt certification requirements
The six sigma green belt certification requirements at ASQ are short. You must have worked in a full-time, paid role, and you need three years of on-the-job experience in one or more of the areas of the Certified Six Sigma Green Belt Body of Knowledge. ASQ grants no educational waivers for this exam, so a degree does not replace any of the three years.
Note what is missing from the list: there is no training requirement, no minimum education and no completed project. The requirements for six sigma green belt certification are about practical work in the field, not about courses.
- 3 years of on-the-job experience in one or more areas of the Green Belt Body of Knowledge
