Why these credentials are trusted
Every level in the Lean Six Sigma family shares the same assurance model.
QA Verified
Every programme in this family 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 each published version. The public 'QA Verified' badge only shows while a valid sign-off is pinned to the current version.
Human-confirmed assessment
Where a level uses a project 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.
Public credential verification
Each credential carries a unique ID and a public verification page that anyone can check — no account required.
Verifiable, quality-assured credential
Each level awards a standalone, verifiable credential (framed at its own governed level) that you can prove to employers.
What does Level 3 mean?
Credentials in this family are pitched at Level 3 depth — RQF Level 3 equivalent — comparable to SCQF Level 6 equivalent in Scotland and EQF Level 4 equivalent across Europe. Each level reflects the depth of guided learning and assessment, giving learners across the UK and Europe a clear point of reference.
