It is positioned at the Professional level. The exam validates the knowledge and skills expected of candidates preparing for IASSC Certified Lean Six Sigma Green Belt.

                                                                      Related certifications include:

                                                                      • IASSC Certified Lean Six Sigma Black Belt

                                                                      The ICGB exam includes 100 questions and allows 180 minutes. Before test day, divide the available time by the number of questions in a timed practice set to establish a steady per-question pace. If a difficult item starts consuming too much time, mark it for review and move forward instead of losing momentum. A full timed practice session can help you decide when to move on, when to return, and how much buffer to reserve for a final check.

                                                                      The passing score for ICGB is 385 out of 500, and the official exam fee is USD 295. Because a retake requires paying the exam fee again, use timed practice results as a readiness check before scheduling your next attempt. If your performance remains inconsistent, continue reviewing weak domains and repeat a timed session before booking the exam.

                                                                      No formal prerequisites or prior certification requirements. Six Sigma training or project experience is recommended but not mandatory.
