How do I register?


Registration for exams goes through the accredited exam/education centres. You can find their details on the exam centres page.

When do I have to register for an exam?


In order to be able to provide all the service needed, we need some time to prepare the exam documentation and get these to all exam centres. Therefore, we have registration deadlines. To know the deadline for your exam centre and your chosen exam date, please contact your exam centre or look at their website. all details concerning the exam centres can be found here.

Can I take an exam in another country?


YES! As a candidate you are free to choose the location where you pass your theoretical tests. This may vary over your curriculum.

Can I go straight to Champion level?


NO! The IIBLC® certification program is a gradual program. This means that you need to go through the different levels if you want to reach the Champion in Lean Certificate.

Do I have to take all the exams to obtain a certificate?


You have to pass the exams associated with the level you want to obtain. You can stop at any level. The exams associated with a certain level are described in the respective pages: Green Belt in LeanBlack Belt in Lean and Champion in Lean and in the general info about the Certification program.

When can I take an exam?


The exam dates are published on the respective pages of the desired level: Green Belt in LeanBlack Belt in Lean and Champion in Lean. You can also find them on the websites of the exam centres.

When do I receive my certificate?


As soon as all the theoretical exams of a certain exam date are processed, we send the results to the exam centre you registered for that particular exam. They will then send it to you. This will include your certificate in case of a positive Green Belt exam. If you passed a theoretical exam for the Black Belt or Champion in Lean, you will only receive a letter with your result and the certificate will be sent to the exam centre you registered for that particular theoretical exam after your practical part has been assessed as satisfactory. It is therefore very important that the exam centre always has your current details!

Who will judge my practical test?


A member of the Content Committee will judge the practical test. However, the judge will never be a fellow countryman of the candidate.

Why is the exam multiple choice?


The theoretical exams are in the form of multiple choice questions to make sure that no interpretation of answers is possible in any way. This kind of questioning ensures a fast, unambiguous method for both answering and correcting the exams. This will also allow us to get your results faster back to you.

How do I know whether I passed?


As soon as we have the results, for either the theoretical or practical test, we send them to the exam centre where you registered for that exam. They then send it to you. You will get a letter with the actual score and, if applicable, your certificate.

Can I view the errors that I made in my exam?


NO! In order to keep the confidentiality of our exams, you will not get detailed feedback per question. However, we give you info on your scoring in the different main domains of the exam.

What does CGBL®, CBBL®, CChL® mean?

What if I cannot take the exam I subscribed for?

Why are the exams on the same day in each country?


This allows for the candidate to take the exam in any location and it ensures the confidentiality of the exams.
