Informational only — not financial or career advice. Exam fees and certification requirements change, and the figures here are accurate only as of the listed verification date. Confirm the current fee and rules directly with the certifying body before you register or budget. We report the official-body exam fee for a single attempt; it excludes prep courses, materials and retakes, and is not the total cost of certifying.
The Lean Six Sigma Green Belt credential, commonly administered through ASQ's Certified Six Sigma Green Belt (CSSGB) program, has published prerequisites that typically include a minimum of three years of work experience. The single-attempt exam fee through ASQ is approximately $438 for non-members, though alternative certification providers may offer lower-cost examination options ranging from $99 to $300. The credential issued by ASQ does not expire and has no mandatory renewal cycle, meaning the certification remains valid indefinitely once earned.
Eligibility requirements, examination fees, and renewal policies are established and may be updated by the issuing body. The fee information stated here is accurate as of June 2026 and is subject to change. Candidates should verify current prerequisites, fees, and all renewal terms directly on ASQ's official certification page or the official website of the specific issuing organization before registering for the examination. This information is provided as a factual overview only and does not constitute guidance on whether to pursue the certification.
