• What Pre-requisites are Needed for a Six Sigma Green Belt?

    | Updated on April 6, 2023

    The eligibility requirements for the Six Sigma certification change depending on the belt level that you are aiming for. There are a total of 6 Sigma belts and you need to fulfill the requirements for each one before getting to the next belt.

    Each belt has a fresh set of requirements. In this article, let us explore the eligibility criteria for Six Sigma Certification, specifically for a Six Sigma Green belt.

    Why are Green Belts important?

    People with Green Belts in the Six Sigma program are given the responsibility of working on projects of a less complex nature that focus towards the improvement of processes.
    They are expected to dedicate less than half of their time to Six Sigma projects and the rest is reserved to their regular employment. The tasks and responsibilities of a Green Belt will change depending on the firm that hires them. Green belt certification is offered by Simplilearn, and it adheres to the norms and guidelines established by IASSC.

    Individuals are tasked with upgrading already established systems.

    The main task of Green belt holders is to work towards improving the overall quality of processes. This contributes to bridging the gap between the theory of Six Sigma and its execution in the actual world. These people play a significant role in either managing projects, reviewing the data, or enhancing it. In the end, they will become familiar with essential tools deployed during the process.

    Candidates for the Green Belt level will also receive education on how to apply DMAIC skills to a Six Sigma project.

    Let’s have a look at the many stages that you will go through, as well as the Six Sigma certification requirements that you will need to fulfill in order to move on to the next step in some of those stages.

    What are the Prerequisites to be a Green Belt?

    You need a working experience of at least three years to be eligible for the Six Sigma Green belt certification.
    The candidate’s main occupation needs to fall into one of the categories that are described in the body of knowledge for the Green Belt. Internships and part-time jobs do not count toward eligibility, and the hours you put in at either one do not build up to a full-time job’s worth of work.
    You should spend some time thinking about the career path you will take, so you can match the work you will receive during the Six Sigma training.

    We suggest writing down some objectives for your personal and professional life.

    A professional with extensive knowledge of the fundamental to advanced components of the Lean Six Sigma Methodology who, typically in a part-time capacity, leads improvement projects, and participates as a team member in more complicated improvement projects led by a Certified Black Belt. This professional is referred to as an IASSC Certified Lean Six Sigma Green Belt (ICGBTM).

    This certification is bestowed to successful candidates by the International Association of Six Sigma Certification Bodies (IASSC). IASSC’s guidelines are followed by each and every one of Simplilearn’s classes and programs. The IASSC Lean Six Sigma Green Belt Body of Knowledge states that a person who possesses a Lean Six Sigma Green Belt has a comprehensive understanding of all aspects of the Lean Six Sigma Method. This understanding includes a level of expertise in the topics that are covered by the phases of Define, Measure, Analyze, Improve, and Control (DMAIC).

    Exams Required to Obtain Certification

    The IASSC Certified Lean Six Sigma Green Belt Test is a proctored, closed-book exam that has a time constraint of three hours and comprises one hundred questions with multiple choice answers. Some copies of the test may include up to 10 more questions; however, these questions will not be evaluated. The examination is proctored in more than 8,000 testing facilities located in 165 different countries, as well as by thousands of IASSC Accredited Providers and through the PeopleCert Online Proctoring system. This examination is comprised of around twenty true/false and multiple-choice questions, one from each important part of the IASSC Lean Six Sigma Green Belt Body of Knowledge.


    A full-time experience of three to four years is required as the minimum experience. There is no way to get credit for internships or experience obtained through working part-time on projects. Candidates for the Six Sigma Green Belt certification need to have appropriate job experience, but in addition, they need to possess the following qualities:

    • Unyielding tenacity and resolve

    • A sensible and analytical mind.

     • A zeal for advancement and growth. 

    • Skills in the art of leadership.

    To be eligible to take the IASSC Certified Lean Six Sigma Green Belt Exam, you do not need to have finished any of the necessary classes first.


    The completion of Lean Six Sigma training from an approved school, a certified Lean Six Sigma trainer, or a corporate program is recommended for individuals who are interested in taking the exam; however, it is not required. Additionally, although having some level of practical Lean Six Sigma job experience and some level of project application experience is not required in order to take the exam, those who choose to do so do have some degree of both of these types of experiences. The IASSC provides candidates with the opportunity to take a Green Belt Evaluation Exam that is neither proctored nor official. You can try this test if you’re not fully prepared to take an official certification exam.

    Certification Professionals will be awarded the IASSC Green Belt Certification if all requirements are successfully completed. This certification is granted by the International Association for Six Sigma Certification, which is a verifiable independent third-party Certification Association that works within the Lean Six Sigma Industry.
