Validates foundational knowledge of Six Sigma fundamentals, the DMAIC phases, basic quality tools and supporting improvement projects.
A good CSSYB course covers the five sections of the ASQ Body of Knowledge and the basic Six Sigma tools, and leaves you with a bound reference for the open-book exam. We compared the main options on coverage, format and price.
Most people should start with Quality Gurus' Udemy course, which follows the CSSYB outline for $130. Choose ASQ's own e-learning if you want structured lessons from the exam owner with a pre-test and post-test, and add the ASQ Handbook to either as your exam-day reference.
| Course | Best for | Format | Price |
|---|---|---|---|
 CSSYB Exam Preparation e-learning | Official ASQ lessons | Interactive | $424 |
 Certified Lean Six Sigma Yellow Belt Training | Low-cost video course | Video | $130 |
| ASQ CSSYB Handbook, 2nd edition | Open-book reference | Book | $150 |
ASQ's self-paced online course reviews the five Body of Knowledge sections in about 8 hours. A pre-test points your study at weak sections and a post-test checks your progress, with 365 days of access from the exam owner.
Great fit if you want structured lessons from the exam owner
Poor fit if you want a cheaper video course; choose Quality Gurus
About 7 hours of video in 80 lectures that follow the CSSYB section order, with short activities such as FMEA and RPN practice. It was last updated in October 2025 and costs under a third of ASQ's course.
Great fit if you want a low-cost video course that follows the ASQ outline
Poor fit if you want ASQ's own materials and tests; choose the ASQ e-learning
A 312-page hardcover that explains the Body of Knowledge section by section, updated for the 2022 CSSYB BoK. Bound references are allowed in the exam, so the same book works for study and on exam day.
Great fit if you learn well from reading and want one reference for study and exam day
Poor fit if you learn better from video or want exam practice; choose Quality Gurus
For most people, Quality Gurus' Udemy course at $130. ASQ's own e-learning is the choice if you want lessons from the exam owner.
No full course here is free. Quality Gurus' free practice tests show where you stand, and since the exam is open book, ASQ's $60 study guide as your reference is the lowest-cost route.
ASQ's course is about 8 hours and Quality Gurus' about 7 hours. Plan for about 25 hours of preparation in total, including practice.
No. CSSYB has no education or work experience requirement.
