Review a list of references that provide the basis for the exam questions. These items give you a better idea of the material covered in the exam. ASQ offers many books and training opportunities to help you prepare.
The CSSGB Question Bank provides sample exam questions based on the CSSGB Body of Knowledge. Includes simulated timed exam and review modes.
The ASQ CSSGB Handbook is a companion guide to your exam's Body of Knowledge. The handbook can be used during your open-book exam!
The ASQ CSSGB Study Guide is intended to help you determine your readiness for the exam, using example questions as a self-assessment tool.
Each certification candidate is required to pass an examination that consists of multiple choice questions that measure comprehension of the Body of Knowledge.
Computer Delivered - The CSSGB examination is a one-part, 110-question exam, and is offered in English only. 100 questions are scored and 10 are unscored. Total appointment time is four-and-a-half-hours, exam time is 4 hours and 18 minutes.
Paper and Pencil - The CSSGB examination is a one-part, 100-question, four-hour exam and is offered in Mandarin in certain locations. View available translated exams, dates and locations here.
All examinations are open book. Each participant must bring his or her own reference materials. Use of reference materials and calculators is explained in the FAQs.
For more information about examination delivery options, including online, remote proctored examination, please visit the computer-based testing page.
If taking the exam CBT you will get your result immediately after submitting the exam. Within 3-5 business days you will receive an email confirming the result. ASQ will also send you a separate email with details on how-to claim your digital certificate and badge through the Accredible platform. Learn more about ASQ digital credentials.
ASQ communicates exam results for exams with updated or new Bodies of Knowledge (pilot exams) within five weeks.
If you do not pass your CBT exam you will receive a summary of your performance via email within 3-5 business days from your initial exam. For 2 years from your previous attempt you can apply at a significantly reduced "retake rate". (Please see Exam Results FAQs for additional details.)
Results for Paper-based tests will be slightly delayed.
Included in this body of knowledge are explanations (subtext) and cognitive levels for each topic or subtopic in the test. These details will be used by the Examination Development Committee as guidelines for writing test questions and are designed to help candidates prepare for the exam by identifying specific content within each topic that can be tested.
Except where specified, the subtext is not intended to limit the subject or be all-inclusive of what might be covered in an exam but is intended to clarify how topics are related to the role of the Certified Six Sigma Green Belt. The descriptor in parentheses at the end of each subtext entry refers to the highest cognitive level at which the topic will be tested. A complete description of cognitive levels is provided at the end of the document.

Calculators such as the Texas Instruments TI-89 or similar are absolutely not allowed because they are programmable.

Manually or hand-stapled documents that are not securely fastened in their covers are not allowed.
Before you enter the exam room, the Test Center Administrator (TCA) will inspect all references. "Post-Its" will be permitted as book tabs only (must be attached prior to entering the test center).
