Green Belt Training & Certification: Course Details & Requirements
Course Format
Our intensive three-day programme is available in multiple formats to suit your learning preferences. You can choose from classroom-based training at our dedicated facilities, live virtual sessions, or in-house training at your company. All formats provide the same comprehensive content and certification path.
Prerequisites & Requirements
While prior Yellow Belt certification is beneficial, it’s not mandatory for Green Belt training. Basic statistical knowledge and some project experience are helpful, but our course is designed to support professionals at various experience levels. Our pre-course materials will help you prepare for the training.
Certification Journey
To achieve the International Lean Six Sigma Institute (ILSSI) Green Belt certification, you’ll complete a two-hour exam with 100 multiple-choice questions to demonstrate your understanding of key concepts and tools. You’ll also have the opportunity to apply what you have learned through a workplace improvement project. Our instructors provide guidance throughout your certification journey, with ongoing support available as you implement your new skills.

Is Lean Six Sigma Green Belt Training Right for You?
Whether you’re a project manager seeking to enhance your process improvement capabilities or a department leader looking to drive efficiency, Green Belt certification will transform your problem-solving and team leadership approach. The skills you’ll gain are particularly valuable if you’re responsible for delivering measurable improvements in your organisation.
Quality professionals and process improvement specialists will find our Green Belt training especially beneficial, as it provides the advanced statistical tools and methodologies needed to tackle complex challenges. For operations managers and business analysts, the course offers a structured approach to identifying, analysing, and solving operational inefficiencies.
Likewise, if your role involves managing teams, analysing data, or implementing change, Green Belt certification will equip you with the expertise to lead significant improvement projects. You’ll develop the strategic thinking and leadership skills needed to drive sustainable change, whether you’re optimising existing processes or implementing new ones across your organisation.
