Lean Six Sigma Green Belt Certification

A Council for Six Sigma Certification (CSSC) Certified Lean Six Sigma Green Belt is an individual that possesses a thorough understanding of enhanced problem-solving skills, with an emphasis on the DMAIC (Define, Measure, Analyze, Improve and Control) model. The Green Belt Certification designation also reflects the knowledge by the individual to serve as a trained team member within his or her function-specific area of the organization. This focus allows the Green Belt to work on small, carefully defined Six Sigma projects, requiring less than a Black Belts full-time commitment to Six Sigma throughout the organization.



The Council for Sigma Certification (CSSC) offers 2 different paths to earning a Lean Six Sigma Green Belt Certification. Individuals who have already received training, and feel that they have significant understanding of the topics covered in the Green Belt Certification “Body of Knowledge,” can simply sit for our standard comprehensive examination.



Individuals who are instead using one of our free Self-Study Guides, either independently or in conjunction with a training provider, can sit for several short exams as they progress through the different sections (as opposed to a single large comprehensive exam).



As an added benefit, those seeking the second option towards Certification would be able to obtain the various levels of our standard certifications (White Belt, Yellow Belt, Green Belt, and Black Belt) as they progress through their certification journey, without incurring any additional examination fees.



Either path will award our official certification(s). Either path is an open-book and non-timed examination format.

We feel the Multiple Exam path to be the most beneficial option for those who are newer to the methodology, professionals looking for a solid refresher, or those candidates who would like to reduce their overall examination/certification costs.



To successfully obtain the professional designation of a CSSC Certified Lean Six Sigma Green Belt (CSSC-CSSGB) issued by The Council for Six Sigma Certification, candidates must successfully complete our CSSC Lean Six Sigma Green Belt Certification Exam and achieve a score of 280 points (or higher) out of a total 400 possible points.



There are no prerequisites for taking the CSSC Lean Six Sigma Green Belt Certification Exam. Once the examination assessment fee is paid, applicants will have 1 year to successfully pass the exam.


There is no project requirement for this Certification. However, this certification is a prerequisite for any individual wishing to pursue our Level II Green Belt Certification, which does have a project participation requirement.



After successfully fulfilling the certification requirements, candidates will receive an Official CSSC Lean Six Sigma Green Belt Certification issued by The Council for Six Sigma Certification, the most respected accrediting organization in the Six Sigma industry.



Our certifications have no expiration date. We strongly feel that certifications that require “renewals” only serve to increase the profits of the certification providers instead of benefiting the individual. Or put another way, a Masters Degree in Business does not expire… why would your professional certification?



Candidates who would like to obtain a more recent certification date can always resit for the certification exam at any time (often for less money than a provider would charge for a “renewal”).



Upon completion of the requirements, individuals are issued a Lean Six Sigma Green Belt Certification in an electronic form. All certifications contain a verifiable certification number and the certification holder is added to the Council for Six Sigma Certification Official Register.
