We have two types of certificates, namely type A and type B. Each serves a different student group's needs. You'll find a sample of A and B below.

  • Certificate type A is awarded after finishing any of our Lean Six Sigma courses completely (including all quizzes). You can get certificate type A for Lean Management, for Lean Six Sigma White Belt, for Lean Six Sigma Green Belt and for Lean Six Sigma Black Belt.

  • Certificate type B is for those who finish all 4 of our Lean Six Sigma courses and also pass our exam. The exam can be taken remotely and is free. These 4 courses should be ours (given that is a free service for our own students) and taken in the order below. ​​

Both type A and B are free. There are no fees. It's an extra service we provide. Full details about the procedure is to be found in the last lecture of each course.  



Based on our experience so far (100,000+ students from 170+ countries), our training, its body of knowledge and certification is accepted across the world. The standards are Dutch, but these are generally accepted across the world. Lean Six Sigma certifications are normally given for life. That principle also applies to our certificates and thus the certificates do not expire.
