IASSC geeft aan welke eisen gelden voor Lean Six Sigma Green Belt certificering ('Universally Accepted Lean Six Sigma Body of Knowledge for Green Belts'). De officiële toets bestaat uit een 3 uur durend - open boek - examen waarin 100 multiple choice vragen moeten worden beantwoord.
Ik ben zelf in opleiding voor Lean Grean Belt en gebruik de onderstaande 'Body of Knowledge (BOK)' als kapstok voor het verzamelen van alles wat ik moet weten voor het examen.
