Updated on 29 September 2026. What’s new: iassc lists the green belt exam at usd $350 and needs no work experience to sit it or to hold the certificate

The ICGB is the IASSC Certified Lean Six Sigma Green Belt exam: 100 closed-book questions in 180 minutes, a 70% pass mark and a USD $350 fee, with no prerequisites to sit it. About 20 questions come from each of five sections, Define, Measure, Analyze, Improve and Control, so no phase can be skipped. This guide sets out the paper, the topics inside every section, how to choose the right hypothesis test and a six-week study plan.

People searching for the ICGB meaning are usually asking two things at once. The letters stand for the IASSC Certified Lean Six Sigma Green Belt, and IASSC is the International Association for Six Sigma Certification, an independent body that certifies knowledge rather than training. It does not run courses. It sets a Body of Knowledge, writes the exam and issues the certificate, which is why the same exam can be reached after a classroom course, a company programme or plain self-study.

Two buttons sit on the SHRM application screen, and one question settles which you press: is the HR work you do today operational or strategic? SHRM-CP is built for professionals who carry out general HR duties; SHRM-SCP is built for those who set HR strategy and policy. Both exams run to 134 questions inside the same four-hour appointment. What changes is the level of judgement each one expects from you.

That single distinction decides more than which exam fee you pay. It decides which half of the SHRM Body of Applied Skills and Knowledge you are scored against, how the situational-judgement questions are marked, and whether the credential you end up holding actually describes the job you do. Choose wrongly and you either sit an exam pitched above your daily work, or you earn a credential that undersells the role you already hold.

This guide is not a pass-first-time playbook. It answers the questions that come before and after that: which of the two credentials belongs on your signature, why the competency half of the exam behaves so differently from the knowledge half, what the three-year recertification cycle really asks of you, and what the letters change about a career once you have them.

SHRM-CP or SHRM-SCP - which one is your exam?

SHRM runs two credentials for the same profession, not a beginner version and an advanced version of one qualification. Both are earned by examination, both draw on the same body of knowledge, and neither expires faster than the other. They differ in the altitude at which they expect you to work.

The ITIL 4 Foundation exam is one of the most important exams in your IT Service Management career.

Updated on 22 September 2026. What’s new: updated for ASQ's 2026 CMQ/OE Body of Knowledge, tested since the July 2026 window, with current exam fees.

You can run every audit on the calendar and still learn about next year's strategy after it has been signed. The ASQ Certified Manager of Quality/Organizational Excellence (CMQ/OE) is built to close that gap. Its real benefit is not a line on a CV. It is tested proof, across seven management domains, that you can argue budgets, risk, suppliers and people in the language a leadership team already uses, and that is what gets quality invited in when decisions are made.

This article treats benefits in the practical sense: what the credential changes in how senior people read your work, who is allowed to apply, what the exam asks under ASQ's 2026 Body of Knowledge, and how to prepare while still doing the job. One clarification first, because the two are often mixed up. CMQ/OE is not the Certified Construction Quality Manager (CCQM), which ASQ aims at construction projects. CMQ/OE is ASQ's general management and leadership credential for quality professionals in any sector, from a ten-person service firm to a multinational manufacturer.

The Lean Six Sigma Black Belt Foundation certification generally takes between 1 to 3 months to study for and complete, depending on the organization you get your certificate through.

Lean Six Sigma Black Belts are mainly involved in analyzing, structuring, and measuring performance issues. Their roles are very separate from the other lean six sigma positions. Black Belt professionals are expected to lead continuous improvement projects and have comprehensive training in enhancing results through Lean concepts and advanced statistical analysis techniques. Lean Six Sigma Black Belts can comprehend team dynamics and assign roles and responsibilities, and they can appreciate and assign roles and responsibilities to team members in a project.

Lean Six Sigma Black Belts are the ones who lead struggles to decrease variation in processes to improve results. They are the ones who teach and advise business leaders and personnel on how to reduce variation, make better choices, and improve outcomes.
