CCSU Six Sigma Green Belt Certificate Program:

Green Belts are Six Sigma practitioners who do process and product improvement project work. The focus of Six Sigma is to reduce and control variation in our processes based on the importance to the customer and the business needs. This training makes extensive use of hands-on exercises, simulations, and sample datasets to practice the application and use of the Six Sigma methods and tools.

Students are required to have a project which may be advanced significantly during the training period through applying the newly learned methods. Students are also required to achieve a satisfactory passing score on the course final exam to demonstrate their proficiency with the Green Belt content. The structure and content of the final exam will be similar to the American Society for Quality (ASQ) Green Belt exam.

CCSU’s Six Sigma Green Belt Certification course, offers a certificate with the emphasis on application through a project. The project must be approved by the instructor.

Additional Information on Six Sigma Green Belt Testing


The Six Sigma Green Belt operates in support of or under the supervision of a Six Sigma Black Belt, analyzes and solves quality problems and is involved in quality improvement projects. A Green Belt is someone with at least three years of work experience who wants to demonstrate his or her knowledge of Six Sigma tools and processes.
Each certification candidate is required to pass an examination that consists of multiple choice questions that measure comprehension of the Body of Knowledge.
Computer Delivered – The CSSGB examination is a one-part, 110-question exam, and is offered in English only. 100 questions are scored and 10 are unscored. Total appointment time is four-and-a-half-hours, exam time is 4 hours and 18 minutes.


The IASSC Certified Lean Six Sigma Green Belt™ (ICGB™) is a professional who is well versed in the core to advanced elements of Lean Six Sigma Methodology, who leads improvement projects and / or serves as a team member as a part of more complex improvement projects lead by a Certified Black Belt, typically in a part-time role. A Lean Six Sigma Green Belt possesses a thorough understanding of all aspects of the Lean Six Sigma Method including competence in subject matters contained within the phases of Define, Measure, Analyze, Improve and Control (DMAIC) as defined by the IASSC Lean Six Sigma Green Belt Body of Knowledge™. A Lean Six Sigma Green Belt understands how to implement, perform, interpret and apply Lean Six Sigma at a high level of proficiency.
