    Exam

    What is the format of the IASSC Yellow Belt exam?

    The IASSC Yellow Belt exam is a closed-book test with multiple-choice and true or false questions covering the five DMAIC phases. It can be taken online with proctoring or at an authorised test centre.

    How many questions are on the exam and how long is it?

    The exam has 60 questions and an allotted time of two hours. Some exam forms include up to six additional unscored pretest questions that do not count toward your result.

    What score do I need to pass the Yellow Belt exam?

    You must achieve a minimum of 230 points out of 300. Questions are spread roughly evenly across the five DMAIC phases, so broad awareness across all areas is the best preparation strategy.

    How and where do I take the exam?

    You can sit the IASSC exam online through the on-demand proctored system or at a Pearson VUE test centre, available in Thailand and across the world. You purchase the exam voucher through the official IASSC ordering system.

    What if I do not pass on the first attempt?

    If you do not pass, you can prepare again and retake the exam. Our training includes practice questions and mock assessments to build your readiness, and our team can support your revision before you resit.

    Will I learn Lean tools as well as Six Sigma?

    Yes. The course introduces Lean concepts integrated within DMAIC, including the seven wastes, 5S, Kanban and Poka-Yoke, alongside core Six Sigma metrics and process mapping techniques.

    Are practice questions and mock tests included?

    Yes. The programme includes practice questions and mock assessments aligned to the 60-question IASSC exam format, helping you identify weak areas and build confidence before exam day.

    Is the courseware aligned to the latest IASSC syllabus?

    Yes. The courseware is mapped to the current IASSC Lean Six Sigma Yellow Belt Body of Knowledge, so you study exactly the concepts the exam evaluates.

    Can a complete beginner follow the course?

    Absolutely. The Yellow Belt is an entry-level credential with no prerequisites, and the training is built for people new to process improvement. Trainers explain each concept from first principles.
