The CLSSBB-001 exam is the official GAQM exam behind GAQM Certified Lean Six Sigma Black Belt (CLSSBB) — passing it earns you the GAQM: Lean Six Sigma certification, a credential positioned at the Advanced / Black Belt level. It is built for candidates who want to validate the skills measured by GAQM Certified Lean Six Sigma Black Belt (CLSSBB). Depending on your track, the exam is also linked to the Certified Lean Six Sigma Yellow Belt (CLSSYB), Certified Lean Six Sigma Green Belt (CLSSGB) and Certified Lean Six Sigma Master Black Belt (CLSSMBB) certifications, so one pass can move you toward more than one GAQM credential.

The CLSSBB-001 exam presents 100 questions to be completed within 120 minutes. That pace leaves little room for second-guessing: read each question carefully on the first pass, flag the ones you want to revisit, and keep moving instead of stalling on a single item. Before exam day, run at least one full timed session in the ValidVCE desktop or online test engine with a comparable question load — a steady rhythm under the clock is a trainable skill, and it is often what separates a pass from a near miss.

To pass the CLSSBB-001 exam you need 70% (70/100 correct answers), and the official registration fee is USD 220 (voucher price). Keep in mind that a failed attempt means paying that fee again in full — retakes are not discounted. Given the cost, self-test before you book: if you can score comfortably above the passing mark on two or three consecutive timed ValidVCE practice tests, your budget is far better spent on the exam itself than on a retake.

No formal prerequisites; e-course recommended but not mandatory. Because GAQM revises its certification programs from time to time, treat this as a starting point rather than the final word. Confirm the current eligibility requirements on the official GAQM exam page before you register.
