APMG International Lean Six Sigma Green Belt Sample Questions

Updated on 15 October 2026. What’s new: the theory exam fee is USD $512, and full Green Belt status also needs a practical assessment of two projects.

Meena, an operations lead at a packaging plant, passes the APMG Lean Six Sigma Green Belt theory exam on a Tuesday and changes her CV to "Green Belt" that evening. The certificate that arrives reads Green Belt Theory. Full status takes a second step: a practical assessment of two real improvement projects. The theory part is 60 multiple-choice questions in 180 minutes, open book, with 63% to pass.

That gap between "passed the exam" and "certified Green Belt" is the detail most short summaries of this credential skip, and it changes how you plan. This guide takes the route in the order you will meet it: what you must pass, how the paper behaves, what the syllabus covers, how to use the books you may carry in, what the project assessors look for, what the route costs in time and money, and what each half of the credential is worth on a CV.

What do you have to pass to be a certified APMG Green Belt?

Two things, in this order. First the Lean Six Sigma Green Belt theory exam, which APMG's booking page lists as version 3.2. Then a practical assessment, in which you submit two Lean Six Sigma projects that show real savings. APMG's own candidate guidance calls it a two-step process: pass the theoretical exam, then pass the practical assessment.
