The Lean Six Sigma Green Belt Refresher course has been designed to reacquaint participants on the Lean Six Sigma fundamentals and its application and is intended for previously certified Green Belts looking to recertify and/or return to executing Lean Six Sigma project. Students are trained and tested on their understanding and ability to apply the tools and techniques of all elements of the Lean Six Sigma DMAIC methodology.

Acuity Institute’s courses are conducted online and use a multi-media format that includes audio from experts, examples of successful performance improvement, interactive simulations and quizzes, and the most current and robust tools and techniques available. This is a “self-paced” online course and can be accessed at any time—and—anywhere, which provides the most flexibility in completing the course. On average, students complete the course in 25 hours (average completion time, actual time may vary).

Upon completion, students will be able to move seamlessly from the training environment back into the workplace and begin leading Lean Six Sigma projects.

Here's what learners had to say about this course


For many of Acuity’s courses, we have assembled a Toolkit, which contains a complete, user-friendly set of the templates included in the course. The toolkit assists practitioners in keeping focused on their project work and not creating “templates”. For ease of use, the templates can be downloaded directly to your computer and are yours to keep and utilize in future projects. The templates have been developed in common formats (MS Word, MS Excel or MS PowerPoint).

SigmaXL Statistical Software

Project leaders will find that data is an important part of Lean Six Sigma projects and statistical analysis software is an indispensable tool at the Black Belt level. Acuity Institute is one of the few Lean Six Sigma Training and Certification organizations who include both the licensed software and detailed instructions for using statistical analysis software in their Lean Six Sigma certification program.

Acuity Institute provides its Black Belts and Green Belts with a full version of SigmaXL statistical analysis software (a perpetual license, which means it is yours to keep), that is a $299 value on its own. SigmaXL is a leading provider of user-friendly Microsoft Excel Add-ins for statistical and graphical analysis. It is powerful but easy to use software that will enable students the ability to apply statistical and data analysis techniques taught in the Lean Six Sigma Black Belt and Green Belt Programs.

If your organization currently uses Minitab statistical software, instructions for this software are also included for each exercise. If you require a Minitab license, please contact us to inquire about cost and details on obtaining a license for this software option.
