Six Sigma
Lean Six Sigma Yellow Belt
What does Level 3 mean?
This credential is pitched at Level 3 depth — comparable to SCQF Level 6 in Scotland and EQF Level 4 across Europe. It reflects the depth of guided learning and assessment, giving learners across the UK and Europe a clear point of reference.
Lean Six Sigma Yellow Belt for operational managers, supervisors and improvement practitioners. Focus on practical DMAIC application, process improvement, waste identification, process mapping, root cause analysis and continuous improvement. Avoid Black Belt statistical depth and advanced mathematical modelling. Use realistic workplace examples and decision-making scenarios. Prioritise practical application over theory and recall. Assess learners through application, interpretation and judgement rather than definitions alone.
Build practitioner-level capability in Six Sigma and earn a verifiable Level 3 credential you can prove to employers.

How the assessment & credential work
AI recommends, a human confirms. Every credential is quality-assured and independently verifiable.
QA Verified content
The programme content passes an automated quality rubric before it can be published — checking accuracy, coverage and assessment integrity.
Human SME sign-off
A subject-matter expert reviews and signs off the published version. The public 'QA Verified' badge only appears while a valid sign-off is pinned to the current version.
Human-confirmed AI assessment
Where a programme uses an assignment, AI produces a recommended grade against a fixed rubric and a human reviewer confirms or overrides it. AI never issues a credential on its own.
Verifiable Level 3 credential
On completion you earn a verifiable Level 3 credential with a unique ID that anyone can check on a public verification page — no account required.
CPD hours
This programme represents approximately 25 learning hours of CPD.
Evidence pack
Your work, assessment outcomes and supporting evidence are collated into an exportable portfolio — ideal for employers, auditors and competence reviews.
