What is the Lean Six Sigma Green Belt Online Training?
The Lean Six Sigma Green Belt online training is a self-paced, 85-hour certification course for professionals in Australia who want to lead process improvement projects. You complete professionally narrated eLearning modules, interactive quizzes and five DMAIC phase tests, and on successful completion you are awarded your Green Belt certificate by Lean Sigma Experts Australia, the training provider behind Six Sigma Online Training Australia.
Green Belts learn to define problems, measure and analyse process performance, deliver medium to high impact improvement projects and achieve measurable cost savings. The course covers the full DMAIC model together with Lean enterprise concepts, so you can identify and remove non-value-added activities across your organisation, customers and suppliers.
Because the course is fully online, you study at your own pace, anywhere in Australia: Sydney, Melbourne, Brisbane, Perth, Adelaide or remote. Your access runs 24/7 for 12 months from the date of purchase, and you can stop and restart from exactly where you left off.

Your certificate, and the optional global exam pathway
On successful completion of the course you are awarded your Lean Six Sigma Green Belt certificate, issued by Lean Sigma Experts Australia (LSEA). It confirms you have completed training that rigorously meets the international standards and practical competencies embedded in the Lean Six Sigma body of knowledge. There is no external exam requirement.
This self-paced course is built to the body of knowledge of the Council for Six Sigma Certification (CSSC). That means you finish fully prepared to sit the external CSSC certification exam, if and when you want it. This is an advantage, not an obligation:
- Most learners use the LSEA certificate as their professional credential. It is backed by CSSC accreditation and a globally aligned body of knowledge.
- If you later want a third-party, internationally portable credential, the streamlined exam-only CSSC certification route is open to you, and this training qualifies you for it.
- As an accredited training organisation, we can advise you on the exam process whenever you are ready.

Frequently asked questions
Do I receive a certificate when I complete the course?
Yes. After completing all eLearning modules and quizzes and passing the five DMAIC tests at 80% or higher, you are awarded your Lean Six Sigma Green Belt certificate, issued directly by Lean Sigma Experts Australia (LSEA).
Do I have to sit an external exam to get certified?
No. The LSEA certificate is awarded on completion of the training. There is no external exam requirement.
What is the optional external exam pathway?
This self-paced course is aligned to the Council for Six Sigma Certification (CSSC) body of knowledge, so you finish fully prepared to sit the CSSC exam-only assessment if you want a third-party, internationally recognised certification. It is a separate, optional process you choose after training, not part of the course.
Do I need the external exam for roles in Australia?
For most roles, the LSEA certificate together with the CSSC-aligned body of knowledge is sufficient. The external CSSC exam mainly matters if an employer specifically requires a third-party credential, or you intend to work in markets where independent certification is expected.

The course is rated at 85 learning hours and you have 12 months of access. Because it is self-paced, most learners complete it comfortably within a few months alongside full-time work.
What are the assessment requirements?
You must complete all eLearning modules and quizzes, and pass all five DMAIC phase tests with a score of 80% or better.
Are there any entry requirements?
There are no formal prerequisites. If you are unsure whether Yellow Belt, Green Belt or Black Belt suits you best, take the Six Sigma Programme Eligibility Quiz on this site.
Is this lean six sigma training recognised in Australia?
