While this page focuses on the practice test and the final exam, remember that the real journey involves understanding the full course and body of knowledge. The exam will require you to not only know the theories but also demonstrate your ability to apply them to practical scenarios. The computer-based delivery (CBT) ensures standard testing and often immediate results.
The actual ASQ CSSBB examination is a challenging, standard test designed to thoroughly evaluate your comprehension of the body of knowledge. Here is what you must be prepared for:
Format: The exam consists entirely of multiple-choice questions. It is a computer-delivered exam (CBT). A limited number of translated paper-based exams may be available, but the standard and widely accessible format is computer-based.
Question Count: A total of 165 multiple-choice questions. Out of these, 150 questions are scored, and 15 are unscored "pre-test" questions, used by ASQ for validation and not affecting your score. You will not know which questions are pre-test, so treat all questions with the same focus.
Time Limit: You are allowed 4 hours and 30 minutes (270 minutes) to complete the entire examination. This includes time for a tutorial and administrative tasks, but the pure testing time is 4 hours and 18 minutes. Manage your time wisely, as you have just under 1.5 minutes per scored question, plus the pre-test questions.
Passing Score: ASQ uses a scaled score system. The range of possible scores typically goes from 200 to 750, with a passing score generally established at 550 or higher. This is not a simple raw percentage but rather a weighted, scaled score based on the difficulty of the specific questions you answer and overall standard setting.
Rules & Materials: The CSSBB exam is a special kind of open book exam. However, there are very strict rules about what materials are allowed. You are generally permitted to use specified official ASQ materials like the The Certified Six Sigma Black Belt Handbook or other authorized books. Critical Rule: No handwritten notes, tabs, or annotations of any kind are allowed within your materials. You cannot bring any additional loose notes, notebooks, or unauthorized electronic devices. Only official texts are permitted and must be presented for inspection at the testing center.
Results: For computer-based tests, you will receive a general "Pass" or "Fail" notification on your screen immediately after completing and submitting your exam. A more detailed official score report, particularly with failure, will follow by email within a few business days.
Passing the ASQ CSSBB exam is a significant achievement and requires structured and intensive preparation. Here are effective strategies and how to proceed:
Utilize Official ASQ Resources: The most reliable materials are from ASQ itself. These include The Certified Six Sigma Black Belt Handbook, study guides, and the official CSSBB Question Bank. The Question Bank is especially valuable as it contains hundreds of practice questions similar in style to the real exam, allowing you to test your knowledge in timed simulation modes. Remember to prepare the specific authorized materials you plan to use in the open-book format, ensuring they meet all annotation rules.
Master the DMAIC Phases: Deeply understand every step and tool in the DMAIC methodology. Focus not just on what they are, but how and when to apply them and what they mean in a real-world project context.
Take Practice Exams Under Conditions: Practice is key. Use reliable CSSBB practice tests (like the official question bank and reputable third-party sources) and take entire exams under strict time limits, simulated exam conditions (quiet space, no distractions), and, crucially, using only your allowed open-book materials. Review your results in detail, understand the logic behind correct answers, and focus additional study time on areas where you are weak.
Consider a Prep Course: Many organizations (ASQ sections, universities, private training providers) offer virtual or in-person CSSBB prep courses. These provide structured learning, expert guidance, and often additional study materials.
Form a Study Group: Collaborating with other candidates can be highly motivating and allow you to learn from different perspectives and discuss challenging concepts.
Focus on Application and Statistics: While general concepts are important, the CSSBB exam heavily emphasizes the practical application of statistical tools. Ensure you can solve complex problems and interpret the results effectively. Practice using your allowed calculator (ASQ has a list of approved calculators - typically non-programmable statistical calculators, check the current policy).
Manage Time and Stress: During study and the exam, break down long study sessions, take regular breaks, and practice relaxation techniques. On exam day, manage your time carefully, mark difficult questions to return to, and trust your training.
Regularly Review the Body of Knowledge (BoK): The official CSSBB BoK is the definitive guide to what will be on the exam. Periodically review it to ensure you have covered all topic areas and have a strong grasp of the material.
Register Early and Plan for Testing Windows: ASQ has specific testing windows throughout the year. Be aware of the dates and registration deadlines to plan your study schedule effectively.
ASQ Registration: Your journey begins by submitting an application and fees through the official ASQ website (asq.org). ASQ will review your application and, once approved, send you an eligibility email.
Exam Delivery: All computer-based CSSBB exams are administered by a leading test delivery partner, which is typically Prometric.
Testing Options: You generally have two options for taking the CBT exam:
Prometric Test Centers: You can select from hundreds of professional Prometric testing centers located globally. You will need to schedule your appointment at your chosen center through the Prometric online scheduling tool once you have your eligibility details.
Remote Proctoring (Online): Prometric also offers an online remote proctoring option for the CSSBB exam (often through their "ProProctor" system). This allows you to take the exam from the comfort of your home or office on your own computer, with a remote proctor monitoring you via webcam and other security measures. You must have a strong and stable internet connection and meet all other hardware and software requirements. Note: Remote proctoring may not be available in all regions or locations, particularly where local in-person testing is mandated (e.g., China).
Paper-Based Testing (Limited): Very limited translated paper-based exams may be available in specific locations and languages. This is not the typical format and has very strict rules and schedules.
Find Your Center/Schedule: After you receive your eligibility information from ASQ, you will go to the Prometric website, locate a test center (if choosing in-person), and select an available date and time within your approved testing window. Follow all of Prometric's identification, scheduling, and reschedule policies.
Day of Exam: Be sure to bring valid, government-issued photo identification. At a test center, you will be given a secure environment and access to your allowed materials (subject to rigorous check). If testing remotely, you will be guided through a check-in process and environmental scan before beginning the exam under live proctoring.
