    Exam

    What is the format of the Green Belt exam?

    The IASSC Green Belt exam is closed book and uses multiple-choice and true or false questions across the five DMAIC phases. It is delivered through online proctoring on demand or at a Pearson VUE test center, so you can choose the option that suits you.

    The exam has 100 questions, with up to 10 additional unscored pretest questions on some forms. You have 3 hours to complete it. Questions are spread roughly evenly across the Define, Measure, Analyze, Improve and Control phases.

    What is the passing score for the Green Belt exam?

    You need a minimum of 385 points out of 550 to pass. Because the questions are balanced across all five DMAIC phases, the best approach is broad mastery rather than focusing on a single area.
