If I am enrolled in the Black Belt Program can I receive the Yellow Belt, Green Belt, or Lean/DFSS (Green Belt) Certification along the way?

If enrolled in our Black Program, our Black Belt Letter of Acknowledgment will list the skills that were covered in the Yellow Belt, Green Belt, and Lean/DFSS sections of your program. However, if you would like, you may request a Yellow Belt, Green Belt, and/or Lean/DFSS Green Belt Certificate by emailing Customer Care after meeting the following requirements.

  • Yellow Belt: Successful 70% passing rate of Black Belt Exams 1-5
  • Green Belt: Successful 70% passing rate of Black Belt Exams 1-8
  • Lean/DFSS Green Belt: Successful 70% passing rate of Black Belt Exams 1-9*

We will provide these additional certificates at no additional charge and the request will not delay your progress in the Black Belt Program.

*Please note: If using “The Six Sigma Handbook: The Complete Guide for Green Belts, Black Belts, and Managers at All Levels, Revised and Expanded Edition” by Thomas Pyzdek (Publisher: McGraw-Hill; 2nd revised edition (March 20, 2003)) the “9th exam” will be “Exam XVI”.


Originally developed by Bill Smith at Motorola in 1986, the Six Sigma Training program was created using some of the most innovative quality improvement methods from the preceding six decades. The term "Six Sigma" is derived from a field of statistics known as process capability. The term 6 Sigma refers to the ability of manufacturing processes to produce a very high proportion of output within specification. Processes that operate with "six sigma quality" over the short term are assumed to produce long-term defect levels below 3.4 defects per million opportunities. Six Sigma's goal is to improve overall processes to that level of quality or better.
