This one-hour timed exam is meant for current MindEdge-certified Six Sigma Green Belts to earn recertification. Recertification is required every three years. This recertification exam tests a practitioner's competency and comprehension of Six Sigma principles, strategies, tools, and techniques. The test includes 50 multiple-choice questions chosen at random from MindEdge's question database, and covers all aspects of the DMAIC methodology and its implementation. Questions are posed in several configurations that ask test takers to identify, calculate, analyze, and apply their knowledge to demonstrate their ability to perform as important members of improvement teams.
