Three Black Belt programme routes
The hours apply to the selected GLSS programme. The 50-hour upgrade builds on Green Belt; the 120-hour Manufacturing and 100-hour Services programmes include foundations from scratch.
| GLSS programme | Programme hours | Starting point | Project requirement |
|---|---|---|---|
| Green Belt to Black Belt | 50 hours | Previous Green Belt learning, reviewed by GLSS. | Classroom or real project required. |
| Black Belt Manufacturing | 120 hours | Start from scratch. No prerequisites. | Classroom or real project required. |
| Black Belt Services | 100 hours | Start from scratch. No prerequisites. | Classroom or real project required. |
Classroom or real project required for every Black Belt route. Agree the project topic, scope, deliverables and support with GLSS. A classroom project does not automatically meet an external certification body’s completed-project requirements.
PeopleCert’s January 2026 syllabus recommends 120 accredited BB training hours and specifies no formal exam entry criteria. Discuss how the selected GLSS programme, previous learning and any further instruction align with your chosen certification.
