The ASQ CSSBB exam can be challenging, especially in the sections that are more difficult, typically the statistics sections.
To provide some assistance, I’m creating this page to provide practice questions and answers for you to learn how to pass the exam, and achieve your Six Sigma Black Belt from ASQ. If you’re pursuing the Green Belt exam, these videos will also help you prepare (although more than you’ll need to know).
There are 10 sections in the Black Belt Body of Knowledge:
I. Certification Overview
II. Enterprise-Wide Deployment
III. Process Management
IV. Team Management
VI. Measure Data
XI. Design for Six Sigma (DFSS)
However, some sections are more difficult than others. Instead of covering all the sections, I’m going to focus on the questions that are most challenging and need the most explanation.
As I build out this page, I’ll continue to add more questions and solutions. If you have a specific request, please contact us and let me know what question you’d like for me to create a video answer.
If you’d like to take a preparation course for the exam, we offer an online CSSBB course every few months.

More questions will be added in early 2024…
