Every level in the Lean Six Sigma family shares the same assurance model.
Every programme in this family passes an automated quality rubric before it can be published — checking accuracy, coverage and assessment integrity.
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.
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.
Each credential carries a unique ID and a public verification page that anyone can check — no account required.
Each level awards a standalone, verifiable Level 3 credential you can prove to employers.
Every credential in this family 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.
The Lean Six Sigma family is a progressive set of Level 3 credentials: Yellow Belt → Green Belt → Black Belt. Each level is a standalone, verifiable credential — start at the level that matches your experience and stack the rest over time.
