CSSC MBB

The exam consists of 150 multiple-choice and true/false questions from the major sections of the CSSC Six Sigma Black Belt Body of Knowledge. It is open-book, and you have 4 hours to complete it. You can take it online or at designated testing centers worldwide. The passing score is 540 out of 600 points (90%).

The exam is challenging because it requires a 90% score and covers the entire Black Belt Body of Knowledge at an expert level. However, it is open-book, so with thorough preparation using the free Self-Study Guide and solid project experience, candidates can succeed. The project component also demands demonstrated proficiency.

You have 3 attempts to pass the exam with the required minimum score. If unsuccessful after 3 attempts, you must pay the examination assessment fee again. Once the fee is paid, you have 1 year to successfully pass the exam.

Once you pay the examination assessment fee, you have 1 year to pass the exam and complete the project requirement. The exam itself takes 4 hours. Project review takes 7-10 business days. If a project is rejected, you can modify and resubmit up to 3 times within 1 year of payment.

You must hold a CSSC Six Sigma Black Belt Level III issued by The Council for Six Sigma Certification and have a minimum of 4 years' previous experience executing Six Sigma projects in a Black Belt capacity (or equivalent). You will need to submit a signed Six Sigma Work Experience Affidavit.

You must submit 3 completed Six Sigma projects following either DMAIC or DMADV methodology. These projects must be completely separate from any project submitted for Black Belt Level II or III. Projects are graded pass/fail by Master Black Belts and typically take 7-10 business days to review.

Yes, you can submit either a 'live' sponsored project or a 'hypothetical' project. If submitting a hypothetical project, you will be graded primarily on the steps taken rather than the actual data submitted. The main purpose is to demonstrate your ability to carry out a Six Sigma project from creation to final stages.

Start by studying the free CSSC Self-Study Guide thoroughly, focusing on the entire Black Belt Body of Knowledge. Practice with sample questions to get used to the format. Since the exam is open-book, organize your reference materials for quick access. Also, ensure your project experience is solid, as the project component tests practical application.

Common failure modes include underestimating the breadth of the Body of Knowledge, not achieving the 90% threshold, and submitting projects that lack clear DMAIC/DMADV steps or sufficient detail. Projects are often rejected for missing key criteria such as project charters, analysis tools, or control plans. Thorough preparation and careful project documentation are essential.
