Lean Six Sigma Black Belt Certification

An individual with a comprehensive mastery of the full Six Sigma Body of Knowledge is an AEC Certified Lean Six Sigma Black Belt. Furthermore, this person is well-versed in the theories and principles of Six Sigma (as well as the related systems and technologies). In addition, the Black Belt Certification credential indicates that the bearer has a solid grasp of team dynamics, leadership, and how to effectively delegate tasks to team members. Last but not least, this person exhibits a thorough comprehension of the DMAIC model in line with Six Sigma principles, a foundational understanding of lean enterprise concepts, and the ability to recognize “non-value-added” operations with ease.

Different Paths of Lean Six Sigma Black Belt Certification:

There are two ways to become a Lean Six Sigma Black Belt Certified using the AEC Certification. Those who feel they have a solid comprehension of the subjects included in the “Body of Knowledge” for the Black Belt Certification and have already completed training can take our usual thorough exam.

Instead of taking a single, large comprehensive exam, those who are using one of our Self-Study programs can take multiple short exams as they move through the various sections, either on their own or in tandem with a training provider.

Additionally, as they advance through their certification journey, individuals pursuing the second option towards Certification will be able to earn the different levels of our standard certifications (White Belt, Yellow Belt, Green Belt, and Black Belt) without having to pay any additional examination fees.

We will grant our official certification(s) via either route.

For applicants who would like to lower their overall examination/certification fees, experts seeking a thorough refresher, or those who are less experienced with the approach, we believe the Multiple Exam path to be the best choice.
