IASSC Green Belt Exam Registration: Fees, Steps, Results

Last checked: 10 November 2026. Prices and procedures can change, so check them on the online testing page on the IASSC website and the exam page on the PeopleCert website before you pay. This guide is independent: it is not affiliated with the International Association for Six Sigma Certification (IASSC), PeopleCert or any government body. It cannot register on your behalf.

In short: you buy an exam voucher, it arrives by email with instructions for booking a time, and you then sit the exam with an online proctor or at a test centre. There are no prerequisites.

Fees

These are the prices shown on the two pages on the day we checked. The price you see can differ by seller, region or tax, so go by the price shown at checkout.

Registration steps

1. Buy a Green Belt (ICGB) exam voucher from IASSC or PeopleCert. IASSC says the voucher arrives by email within minutes, with instructions for booking your exam.
2. Book your exam by following the voucher instructions. For online exams, IASSC says you can sit the exam in as little as 72 hours at no extra cost, or sooner for an extra fee. Test centres and accredited training providers are also options.
3. Prepare what is allowed: a standard or scientific non-programmable calculator (online exams have one built into the platform). Do not bring the Reference Document; it is available inside the exam.
4. Sit the exam: 100 questions in 180 minutes, with a pass mark of 70%. The syllabus allows an extra 45 minutes for non-native speakers, so ask about it when you book.

After the exam

• Results: PeopleCert says it announces final results within 2 business days after your answers are officially submitted, and holds results back if your profile is missing information.
• Certificate: IASSC issues a PDF certificate with a certification number and a badge, and adds you to its certification register.
• Validity: the certification stays "Current" for three years. To keep it, PeopleCert says you take the recertification exam (50 questions in 90 minutes, pass mark 70%).

Before you buy the voucher, try the free questions to see where you stand, then review the exam content and weights.
