The CLSSBB-001 exam is the official GAQM exam behind the GAQM: Lean Six Sigma certification, validating the skills measured by the GAQM Certified Lean Six Sigma Black Belt (CLSSBB) credential. It sits at the Advanced / Black Belt level of the GAQM certification program. It also connects to Certified Lean Six Sigma Yellow Belt (CLSSYB), Certified Lean Six Sigma Green Belt (CLSSGB), Certified Lean Six Sigma Master Black Belt (CLSSMBB), so the knowledge you build here carries over to those tracks as well.

The CLSSBB-001 exam contains 100 questions to be completed within 120 minutes. Before exam day, divide the available time by the question count to work out a comfortable per-question pace, and mark any item that eats into it so you can return later instead of getting stuck. Timed sessions in the PrepAwayPDF test engines make that pacing automatic — run at least two full-length mock exams under the clock so time pressure never becomes the reason you drop points.

The passing score for the CLSSBB-001 exam is 70% (70/100 correct answers), and the official registration fee is USD 220 (voucher price). Retakes are not discounted — every new attempt means paying the full fee again — so it pays to measure yourself before you book. Work through the 252 practice questions on PrepAwayPDF, sit a timed practice test, and schedule your exam only when your scores are consistently comfortable. That simple habit is the cheapest exam strategy there is.

No formal prerequisites; e-course recommended but not mandatory. Requirements can change when GAQM revises its certification program, so confirm the current eligibility rules on the official exam page before you register.
