Certification Process

The training

The training consists of a series of online modules that you will complete in sequence. Each module consists of a lesson, a quiz, and an assignment.

Lessons were developed and are presented by Thomas Pyzdek and are highly interactive. Quizzes are multiple-choice and because they are self-scoring, you will receive immediate feedback as soon as you submit it. Assignments must be submitted so that your assigned instructor can grade them and provide you with feedback.

To be clear, even though the program is self-paced and 100% online, you will have a Pyzdek Institute certified Master Black Belt going through your work, grading your assignments, providing you with feedback, answering questions, etc. Once all the required activities in the training are completed with satisfactory grades, you will be awarded a Lean Six Sigma Green Belt Bronze certificate. This certificate of completion is published on a public database and you may include it on your resume.

A Comprehensive Exam

Once training is completed, you must pass a comprehensive proctored exam. This means that you must take the exam on a computer that has access to a webcam and a microphone. The exam is open book and open notes; however, it is proctored because we must authenticate you before the exam begins. The proctor will be able to see you and your desktop while you take the exam. No other person is allowed in the room while you complete the exam.

When you pass the exam, you will be awarded a Lean Six Sigma Green Belt Silver certificate. At this point you become a trained Lean Six Sigma Green Belt, but not a certified one yet.

In order to receive a full Lean Six Sigma Green Belt certification, you must complete a real-world project. This project will be reviewed and graded by a Master Black Belt. You will gain access to a project management software with all necessary tools and templates while you work on your project.

You will then begin by submitting a project idea to a steering committee for review. Once the idea your approved, you may begin working on your certification project.

During these Tollgate Reviews, you will receive the necessary feedback on your progress, as well as guidance for the next phase (e.g. we will help you choose the correct tools to use during the next phase).

Once your project is graded satisfactory, you will make a live presentation via to Thomas Pyzdek and your instructor (you may also invite your senior leaders if you find it convenient). It is at this point that we will fully certify you as a Lean Six Sigma Green Belt.
