PHR – Practice Exams

One thousand five hundred original practice questions for the IASSC Certified Lean Six Sigma Green Belt (ICGB) — the working practitioner’s DMAIC credential from the International Association for Six Sigma Certification. The bank follows IASSC’s published Body of Knowledge across the five phases: Define (270 questions), Measure (360), Analyze (330), Improve (240), and Control (300) — at Green Belt depth throughout (the Improve phase is regression-only, per the published outline). Every question carries an explanation and a topic tag. The real exam mixes multiple-choice with true/false questions; this bank trains you with four-option multiple-choice questions throughout. This product prepares you for the examination only; it does not confer the certification.
