Prepare for the exam
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.
*Note: In September 2022, along with the pilot of the new SSYB Body of Knowledge, the SSYB examination will increase by five questions for a total of 90 questions (80 scored, 10 unscored) for computer-delivered exams, and 80 questions (80 scored) for paper and pencil delivered exams.
What Happens if I pass/fail?
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.
The topics in this Body of Knowledge include additional detail in the form of subtext explanations and the cognitive level at which test questions will be written. This information will provide guidance for the candidate preparing to take the exam.
The subtext is not intended to limit the subject matter or be all-inclusive of what might be covered in an exam. It is meant to clarify the type of content to be included in the exam. The descriptor in parentheses at the end of each entry refers to the maximum cognitive level at which the topic will be tested. A complete description of cognitive levels is provided at the end of the document.
Please note: The new Certified Six Sigma Yellow Belt Body of Knowledge will be tested starting with the September 2022 testing window. Examination results for the September pilot examination will be sent out four to six weeks after sitting for the exam. Compare the 2015 and 2022 CSSYB BoKs

All computer-based exams feature a basic scientific calculator on-screen in the exam. Prometric Test Center Administrators can provide you with a hand-held basic calculator upon request.
Any silent, hand-held, battery-operated calculator with no programmable memory will be permitted. Programmable calculators tend to have graphing capabilities, the ability to store text/alphanumeric data by the input of the user, and a function (fn, F1, F2, etc.) button.
Calculators such as the Texas Instruments TI-89 or similar are absolutely not allowed because they are programmable.
Prometric will provide you scratch paper and pencils.
All ASQ exams are open book and all reference materials (including all forms of notes) must be bound and remain bound during the exam.
Bound refers to material permanently bound by stitching or glue and materials fastened securely in its cover by fasteners, which penetrate all papers (i.e., ring binders, spiral binders, plastic snap binders, brads, or screw posts).
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).
If you wish to change your exam appointment date or time, you must do so at least five days prior to your appointment using the Reschedule/Cancel option on Prometric's website, or by contacting Prometric's automated voice response system. There is a $100 fee for changing an appointment. Failure to appear for your exam appointment will result in a loss of all applications fees.
Items strictly prohibited in the exam area: hand-stapled materials, blank writing tablets or tablets containing blank pages, unbound tablets, unbound notes, slide charts and/or wheel charts (hand-held cardboard or plastic calculating devices with rotating or sliding pieces).
