Lean Six Sigma World is an ILSSI-accredited Lean Six Sigma training and certification academy that helps professionals, students, and organisations master process improvement and build careers that last. From White Belt to Black Belt, our internationally recognised certifications are taught by experienced Master Black Belt trainers who have led real improvement projects across manufacturing, healthcare, finance, IT, supply chain, and more.
We exist to make world-class Lean Six Sigma education accessible, practical, and genuinely career-changing, wherever you are in the world.
Our mission
In the words of Dr. A. P. J. Abdul Kalam, “All of us do not have equal talent, but all of us have an equal opportunity to develop our talents.” That belief sits at the heart of what we do. Our mission is to give every learner the same opportunity for self-reinvention and career success that Lean Six Sigma can unlock, by teaching the method clearly, honestly, and in a way you can apply the very next day at work.
What we offer: Lean Six Sigma certification, White Belt to Black Belt
We deliver ILSSI-accredited Lean Six Sigma certification across four belt levels, each building on the last:
- White Belt Certification: the foundations and language of Lean Six Sigma, built for complete beginners.
- Yellow Belt Certification: become a confident, useful contributor on improvement projects.
- Green Belt Certification: learn to lead your own Lean Six Sigma projects from start to finish.
- Black Belt Certification: master advanced tools, lead complex projects, and mentor others.

Frequently asked questions
Is Lean Six Sigma World certification accredited?
Yes. Lean Six Sigma World is a division of ILSSI, the International Lean Six Sigma Institute in Cambridge, England, so our certifications are ILSSI-accredited and recognised internationally.
Which Lean Six Sigma belt should I start with?
If you are new, start with White or Yellow Belt. Choose Green Belt if you want to lead your own projects, and Black Belt once you have some project experience. Most people begin with Yellow or Green depending on their goal.

Yes. All of our Lean Six Sigma courses are available online and self-paced, so you can study around your work and life and complete your certification at your own speed.
