Free CLSSBB: Certified Lean Six Sigma Black Belt Exam Questions and Answers
Certified Lean Six Sigma Black Belt is exam CLSSBB, part of GAQM certification from the Global Association for Quality Management, a private certification vendor. GAQM authors, sets and marks its own exams, and it is not an accredited certification body in the way ISACA, EC-Council or ISC2 are: it claims no ISO/IEC 17024, ANAB or UKAS personnel-certification accreditation anywhere, the ISO 9001 certificate it cites covers its own management system rather than its exams, and the ASIC listing it points to is a Membership tier that sits below ASIC's accreditation ladder — in a scope that covers institutions, not certification schemes. So a GAQM credential is vendor-set. The exams themselves run 40 to 100 multiple-choice questions in 60 to 120 minutes, usually at 70% to pass, AI-proctored, with vouchers valid eight months and two attempts included, and most carry no experience prerequisite.
