After the training, you have the opportunity to be certified by us as a Lean Green, Black or Master Black Belt. You do this by taking a theory test on your knowledge of Lean. You will be given a theory test. You will also demonstrate your ability to improve processes by carrying out an improvement project using Lean techniques. You can register via this page for either your theory certification only or your practical certification or both at the same time.

Registration for the open certification is only valid for participants in the Lean Green Belt, Lean Black Belt and Lean Master Black Belt courses.

About our certifications

What does a certification look like?
 After the training, you have the opportunity to be certified by us as a Lean Black Belt. You do this by taking a theory test on your knowledge of Lean. You will be asked several open questions (at insight level, so no repeating rows) and a case study to work out.

You will also demonstrate through your practical assignment that you are able to improve processes with the help of Lean techniques by carrying out an improvement project. We advise you to also start your improvement project within your own team or department at the start of this training. This way we take your own practice as a starting point and help you to really get started with Lean in your daily work. We are happy to help you complete this training and your improvement project successfully! Experience shows that participants with coaching by one of our experienced Master Black Belts complete their projects faster and with greater impact and results. So it is a very good investment in yourself and your project to have yourself coached towards practical certification.

If you want to be certified as a Lean Black Belt, we recommend that you also purchase a minimum of 8 hours of coaching. In addition, you can purchase strip cards for an extra 4 hours if desired. Please contact us for more information about the different possibilities. In principle, the coaching can be scheduled per hour and is done online (via Teams or Zoom). If you wish to have coaching on location this is also possible but then the minimum commitment of the coach is 4 hours per appointment.

When did I pass?
A certification always consists of a theoretical and a practical part. For both parts you need to score at least a 5,5. In addition, the weighting is 50:50. So if you score a 7 for your theory and a 9 for your practical assignment, your final mark will be an 8. If, in the opinion of the examiner (always an experienced senior trainer / advisor) you meet the requirements, then you have passed without further ado (with the exception of the Master Black Belt, here there are always 2 examiners present). If you do not meet the requirements or if the examiner has doubts about certain parts, it is up to the examination board to assess and make a decision. If this leads to a "fail" assessment, you are entitled to a resit. In addition, the examiner will also indicate what is needed in order to still meet the requirements. So again, you don't necessarily fail without an end-to-end value stream analysis, but you do have a lot more to explain! Fortunately, we see that the vast majority of candidates pass at once. Only a small minority needs a resit. This should give you confidence: if you take Lean seriously, the chances are high that you will succeed!

Can I get coaching on my A3?
 If you want to be certified, we recommend that you also purchase a minimum of 6 hours (Green Belt) or 8 hours (Black Belt) of coaching. In addition, you can purchase strip cards for an extra 4 hours if desired. Please contact us for more information about the different possibilities. In principle, the coaching can be scheduled per hour and is done online (via Teams or Zoom). If you wish to have coaching on location this is also possible but then the minimum commitment of the coach is 4 hours per appointment.

Are there any costs associated with certification?
Yes, certification is optional. A Green Belt certification costs EUR600 and a Black Belt certification costs EUR 875 (theory+practice all-in). You can also purchase an all-in coaching+certification package from us. During your improvement project we will support you through coaching.

Within how many months after completion of my training can I certify?
That is up to you. After following the course you are free to decide whether you want to go for certification and if so, how soon. Certification consists of a theoretical and a practical part. Because you already had the theory part during the course, we advise you to complete your practical assignment within six months after completing the course and get certified.

How long will my certificate be valid?
Your certificate remains valid, there is no end date to the validity of the certificate.

Are LMI's training courses accredited?
The dictionary definition of accreditation: "The official recognition that an institution has met standards which make it eligible for membership of an association or society of equals". This system gives the customer a simple tool to determine the reliability of the service or product delivered. Because we are part of the Lean Global Network, founded by the founders of Lean Womack & Jones, we are accredited. You can't get any closer to the source! Our Master Black Belt Lean Postgraduate Program is accredited by the European Union, and the Universitat Polytechnic de Catalyuna (UPC) in Barcelona. The activities we perform with Nyenrode are accredited by EQUIS (EFMD) and the Ministry of Education.
