If you are looking forward to a career opportunity in Quality Management under manufacturing, pharmaceutical, healthcare, technology or service industry, it is most likely that your prospective employer will prefer your resume if you are Six Sigma or Lean Six Sigma qualified.

If you are considering a career move in the arena of quality management then you can take up the Six Sigma Green Belt certification while if you are an experienced professional working on Six Sigma projects for more than three years and look forward to manage Six Sigma projects full-time, you should consider taking up a Six Sigma Black Belt certification.

As the world is moving towards Lean Six Sigma, and most organizations adopting the collaborative approach of Lean and Six Sigma for quality management, it is recommended to take up a Lean Six Sigma Green Belt for beginners. If you already have a Six Sigma Green Belt (SSGB) or Lean Six Sigma Green Belt (LSSGB) or don’t have any of these but have enough experience in Lean Six Sigma projects you can take up the Lean Six Sigma Black Belt (LSSBB) to master the art of managing Lean Six Sigma-based projects.


If you look forward to mentor and train professionals, consult on projects, and involve yourself in strategy building for an organization, then the Master Black Belt (Six Sigma Master Black Belt or Lean Six Sigma Master Black Belt) certification is recommended for you.

Choosing the Right Accreditation Body             

Global Accreditation Brings Credibility

As there is no official body designated to solely conduct Six Sigma and Lean Six Sigma trainings and grant certifications to qualified professional, many companies have developed their own guidelines and offer trainings and certifications. However there are two accrediting bodies that are the most noted and recognized by the leading global organizations and bodies.

American Society for Quality (ASQ), a global community of people dedicated to Quality & Six Sigma, ensures that professional training and certifications are conducted according to global industry standards. It is advisable to ensure that your Six Sigma training partner provides courseware accredited by or in accordance with the guidelines laid by ASQ. Please note that ASQ does not offer certification/accreditation for Lean Six Sigma, but offers certification/accreditation for all the levels of Six Sigma.

International Association of Six Sigma Certification (IASSC), similar to ASQ, is a reputed, third-party certification body that facilitates and delivers all Lean Six Sigma certification examinations for professionals who qualify eligibilities.

Choosing Your Training Partner

Six Sigma and Lean Six Sigma both involve highly technical methods & tools, need thorough knowledge, and expertise in application of relevant concepts. In case you pick just any training and certification company for your training, there’s a good chance that you will not get standard training and industry related guidance.

Some pointers to keep in mind before enrolling to any training and certification institution:

Organization’s Accreditation

While choosing the training partner, make sure you choose one which is duly accredited by either ASQ or IASSC. The right accrediting body would depend on your course choice (Six Sigma or Lean Six Sigma). Choosing the right accredited training partner would ensure that the training you are receiving is in accordance with the guidelines laid by the accrediting body. Also, you do not miss on any topics included in examination blueprints.

Mode of Training

You should consider a training partner that offers training in a mode that is suitable to you and you have options to choose from. Some training partners offer trainings under classroom workshops, instructor-led online classroom and online self-learning options. In such a situation, you have an option to choose the best fit according to your liking. We at Simplilearn believe that, instructor-led online classroom training is preferred by professionals over classroom workshops or an online self-learning course as it gives professionals a flexibility to attend a classroom session from experts from the ease of their home.

Training Duration

Some training partners offer you multiple duration option for the trainings. Some are crisp for a duration of one or two days, while other are more elaborated and spread across 4-5 day. Based on your pre-preparation level you can choose between the two.

You can consider Simplilearn as your training partner, as it offers you the flexibility to choose from various learning modes and has trained more than 200,000 professionals. Also, it is accredited by IASSC and ASQ for the respective course offerings.

Certification Eligibilities, Examinations and Responsibilities
