There is no single body assigned to give Six Sigma certificate to the quality profession. Some of the Six Sigma training and Certification providers are ASQ, GreyCampus, AcoSixsigma, Acknowledge Benelux, BMGI, PIM Training & Consulting, etc.
But to become a Six Sigma Green Belt Certified from any of the certification providers, you need to follow some process. Six Sigma Green Belt certification involves learning the appropriate subject matter, passing a written proficiency examination and displaying competency in a hands‐on environment. The materials can be purchased from almost any Six Sigma training and consulting company, but many of them undergo classroom training to attain knowledge related to all methodologies. You can check the above list to get training providers.
Once you complete the training, you will have to pass the written examination that consists of multiple-choice questions that measure the understanding of the Green Belt Body of Knowledge. The examination will be conducted by the Training company itself. The Six Sigma Green Belt Certification exam consists of 100 multiple‐choice questions with a time duration of four hours. It is offered in the English language only.
Once you e pass the exam with 50% or above then you need to complete one or two quality projects related to Green Belt concepts. Six Sigma Green Belt certification requirements vary from company to company.
